Medical Uses of Baking Soda in Daily Life

14. Diaper Rash Relief Baking soda’s gentle anti-irritant properties make it a useful home remedy for soothing mild diaper rash in babies. Its alkalinity can help… Diana Yasinskaya - August 11, 2025

According to a recent survey by the Statista Research Department, nearly 60% of households in the United States report using baking soda for medical or health-related purposes. Most commonly, its applications involve the digestive system—such as relieving heartburn—and the integumentary system, including soothing skin irritations. However, distinguishing between safe home remedies and medical situations requiring professional attention remains a significant challenge. As baking soda’s popularity grows, understanding when and how to use it safely is essential for optimal health outcomes.

1. Heartburn Relief

Baking soda, or sodium bicarbonate, acts as an antacid by neutralizing excess stomach acid. When heartburn strikes, it causes a burning sensation in the chest caused by acid refluxing into the esophagus. Mixing half a teaspoon of baking soda in a glass of water is a common home remedy for occasional heartburn, providing quick, temporary relief. This solution works by increasing the pH in the stomach, thus counteracting acidity and easing discomfort. However, baking soda is not intended for frequent or long-term use, as overuse can disrupt the body’s acid-base balance and cause side effects such as metabolic alkalosis or increased sodium intake. Individuals with chronic heartburn or underlying health issues should exercise caution. According to the Mayo Clinic, persistent heartburn may signal a more serious condition, like gastroesophageal reflux disease (GERD), that requires professional evaluation. If heartburn occurs more than twice a week, is severe, or is accompanied by symptoms such as chest pain or difficulty swallowing, it is important to seek medical advice rather than relying solely on home remedies like baking soda.

Baking soda is frequently used as a gentle remedy to ease the discomfort caused by mouth ulcers, also known as canker sores. Its mild alkalinity neutralizes acids in the mouth, helping to reduce irritation and promote healing. Compared to commercial mouth rinses, which may contain alcohol or artificial additives, a baking soda rinse offers a simple and low-cost alternative for mild cases. To prepare a rinse, dissolve one teaspoon of baking soda in half a cup of warm water, then swish the solution in the mouth for 15-30 seconds before spitting it out. This can be repeated several times daily but should not be swallowed. The UK National Health Service (NHS) recommends saline or baking soda rinses for minor mouth ulcers, noting their ability to soothe pain and keep the area clean. However, if ulcers persist for more than three weeks, recur frequently, or are accompanied by other concerning symptoms, it is important to consult a healthcare professional to rule out underlying conditions. While baking soda rinses can be beneficial, they should be used with caution and never as a substitute for medical diagnosis or treatment when symptoms are severe or persistent.

3. Toothpaste Alternative

Baking soda’s mild abrasive properties make it an effective alternative to commercial toothpaste for removing surface stains and plaque from teeth. Its ability to neutralize acids in the mouth can also help reduce the risk of tooth decay by balancing oral pH. Many whitening toothpastes incorporate baking soda as a key ingredient, leveraging its gentle abrasiveness to polish away discoloration and brighten enamel. However, using pure baking soda should be approached with care; overuse can wear down tooth enamel and irritate gums. The American Dental Association (ADA) recognizes the cleaning effectiveness of baking soda, but recommends limiting its direct use to a few times per week rather than daily. To use, dampen a toothbrush, dip it in a small amount of baking soda, and brush gently for about two minutes, avoiding excessive pressure. It is important not to replace fluoride toothpaste entirely, as baking soda does not provide the cavity protection that fluoride offers. If you experience increased tooth sensitivity or gum irritation, discontinue use and consult a dental professional. Baking soda is most beneficial when used occasionally as part of a broader oral hygiene routine.

4. Denture Cleaner

Baking soda is widely valued for its ability to remove stains and neutralize odors from dentures, making it a practical and inexpensive alternative to commercial cleaning tablets. Its gentle abrasive action helps lift plaque, food particles, and surface discoloration without scratching the denture material. Unlike some commercial cleansers that may contain harsh chemicals or strong fragrances, baking soda is non-toxic and unlikely to irritate sensitive oral tissues. According to the Centers for Disease Control and Prevention (CDC), regular cleaning is essential for denture wearers to prevent infections and maintain oral health. To clean dentures with baking soda, dissolve one to two teaspoons in a cup of warm water and soak the dentures for 15-30 minutes. After soaking, use a soft toothbrush dipped in baking soda to gently scrub all surfaces, then rinse thoroughly under running water. While commercial effervescent tablets may offer additional antibacterial ingredients, baking soda is effective for routine cleaning and odor control. However, it does not disinfect dentures, so periodic use of specialized cleansers is still recommended. Always consult your dentist for personalized cleaning advice, especially if your dentures have metal components or special coatings.

5. Breath Freshener

Baking soda effectively neutralizes odors in the mouth, making it a useful option for freshening breath. Unlike mints or chewing gum, which primarily mask unpleasant smells with flavor and fragrance, baking soda targets the source by neutralizing acidic compounds produced by oral bacteria. This chemical action helps eliminate instead of merely covering up bad breath, leading to a cleaner, fresher mouth. A simple baking soda mouth rinse can be made by dissolving half a teaspoon of baking soda in a glass of warm water and swishing the solution around the mouth for 30 seconds before spitting it out. This process can be repeated as needed, particularly after meals or in situations where brushing is not possible. According to the American Dental Association, regular oral hygiene and neutralizing mouth rinses can help control bad breath more effectively than flavored products alone. However, persistent halitosis may signal underlying dental or medical issues, such as gum disease or digestive problems, and should be evaluated by a dentist. Baking soda rinses are best used as a supplement to, rather than a substitute for, comprehensive oral care and professional dental checkups.

6. Skin Irritation Relief

Baking soda is often used to alleviate mild skin irritations, thanks to its anti-inflammatory and soothing properties. When applied to itchy rashes or insect bites, baking soda can help reduce redness, swelling, and discomfort. Compared to calamine lotion, which works by drying out oozing skin and providing a cooling effect, baking soda offers a gentle, natural alternative for minor irritations without added dyes or medications. For localized areas, mix one to two teaspoons of baking soda with a small amount of water to create a thick paste and apply directly to the affected skin for 10-15 minutes before rinsing with cool water. For more widespread itching, such as from sunburn or contact dermatitis, add half a cup of baking soda to a lukewarm bath and soak for 15-20 minutes. The American Academy of Dermatology recommends baking soda baths for relief from itching and irritation. However, baking soda should not be used on broken skin or chronic wounds, and persistent or severe symptoms may indicate a more serious condition requiring medical attention. Always discontinue use if irritation worsens or an allergic reaction develops.

7. Itchy Insect Bite Soothe

Baking soda is a popular home remedy for relieving the itch and discomfort associated with insect bites. Its alkalinity helps neutralize the acidic components of insect venom, which can reduce local irritation and swelling. While antihistamine creams work by blocking the body’s allergic response and reducing inflammation, baking soda provides a simple, drug-free alternative for mild bites. To use, mix one tablespoon of baking soda with just enough water to form a thick paste, then apply it directly to the bite for 10-15 minutes before rinsing off with cool water. This method can be repeated up to three times daily as needed for symptom relief. According to the Centers for Disease Control and Prevention (CDC), baking soda is an effective option for soothing minor bites from mosquitoes, fleas, or ants. However, if a bite becomes increasingly red, swollen, or painful, or is accompanied by signs of an allergic reaction such as difficulty breathing or widespread hives, immediate medical attention is necessary. Baking soda should not replace prescribed treatments for severe reactions or infections but can be a helpful addition to at-home first aid for minor bites.

8. Sunburn Relief

Baking soda is often used as a home remedy to provide cooling and anti-itch effects for mild sunburns. Its alkaline nature can help neutralize the skin’s pH, reducing itching and soothing inflammation caused by overexposure to ultraviolet rays. While aloe-based gels are a popular commercial solution known for their hydrating and anti-inflammatory properties, baking soda offers a non-greasy, easily accessible alternative, especially for those who may be sensitive to topical gels or fragrances. For sunburn relief, dissolve half a cup of baking soda in a bathtub filled with cool or lukewarm water, then soak for 15-20 minutes. This bath can provide generalized comfort, relieve itching, and help the skin feel cooler. Avoid scrubbing the skin or using hot water, which can worsen irritation. According to the American Academy of Dermatology, soaking in a baking soda bath and applying a cool compress can offer symptomatic relief for mild sunburns. However, if blistering, severe pain, fever, or dehydration develops, medical attention should be sought promptly. Baking soda baths are best used as a supportive measure alongside hydration and sunburn-specific aftercare.

Baking soda is a commonly used home remedy to calm skin irritation resulting from contact with poisonous plants such as poison ivy or poison oak. Its alkaline nature can help neutralize the acidic oils (urushiol) left on the skin, thereby reducing itchiness, redness, and inflammation. While hydrocortisone creams are often recommended as the gold standard for treating allergic reactions from these plants due to their strong anti-inflammatory effect, baking soda offers a fragrance-free and readily available alternative for mild symptoms. For localized rashes, mix three teaspoons of baking soda with one teaspoon of water to form a paste and gently apply it to affected areas. Leave the paste on for 10-15 minutes before rinsing off with cool water. For more widespread reactions, add one cup of baking soda to a cool bath and soak for 20-30 minutes to help soothe the skin and relieve discomfort. The Centers for Disease Control and Prevention (CDC) recommends baking soda paste or baths as supportive measures for minor plant-induced rashes. However, if symptoms are severe, widespread, or involve the face or genitals, or if there is any sign of infection, it is essential to seek medical attention promptly.

10. Athlete’s Foot Relief

Baking soda is known for its mild antifungal and drying properties, making it a popular home remedy for alleviating the discomfort associated with athlete’s foot. This common fungal infection thrives in moist environments, leading to itching, burning, and flaking between the toes. Baking soda works by absorbing excess moisture and creating an environment less favorable for fungal growth, similar to some over-the-counter antifungal powders. While it does not fully eradicate the fungus, it can help control symptoms and reduce odor. To use, dissolve three to four tablespoons of baking soda in a basin of warm water and soak the feet for 15-20 minutes daily. After soaking, dry the feet thoroughly, especially between the toes, to minimize moisture. According to the American Academy of Dermatology, keeping feet dry is a crucial part of athlete’s foot management, and baking soda soaks can be a useful adjunct to proper foot hygiene. However, persistent or severe cases may require topical or oral antifungal medications. If symptoms worsen or fail to improve after a week of home treatment, or if there are signs of secondary infection, professional medical advice should be sought.

11. Body Odor Neutralization

Baking soda is widely recognized for its ability to absorb and neutralize unpleasant body odors, especially in areas prone to sweating such as the underarms and feet. Its alkaline nature helps counteract the acidic byproducts of bacterial metabolism, which are responsible for most body odor. Unlike commercial deodorants that often contain fragrances and aluminum-based compounds to mask or block perspiration, baking soda provides a simple, fragrance-free alternative that targets the source of odor. To use, sprinkle a small amount of dry baking soda directly onto clean, dry skin in the underarm or on the feet, or mix with a little water to form a paste for more even application. Allow it to sit for a few minutes before dusting off any excess. The Cleveland Clinic notes that natural deodorants containing baking soda are increasingly popular among individuals seeking to avoid synthetic chemicals. However, frequent or excessive use may cause skin irritation in sensitive individuals. If redness, itching, or a rash develops, discontinue use and try gentler alternatives. For those with persistent or strong body odor, consulting a healthcare professional is recommended to rule out underlying medical conditions.

12. Minor Burn Soothing

Baking soda can provide mild analgesic and anti-inflammatory effects for minor, superficial burns, such as those from brief contact with hot objects or liquids. Its alkaline composition helps reduce stinging and soothe inflamed skin. While immediate cooling under cold running water remains the gold standard for first aid—helping to dissipate heat and minimize tissue damage—baking soda may offer additional comfort once the initial cooling is complete. To use, dissolve one to two teaspoons of baking soda in a cup of cool water, soak a clean cloth in the solution, and gently apply it as a compress to the affected area for 10-15 minutes. This may help reduce itching and promote a sense of relief. According to the NHS, only minor burns that do not break the skin or cause blistering are suitable for home management; more serious injuries require professional assessment. Baking soda should never be applied to open wounds or severe burns, as it may interfere with healing and increase infection risk. Always monitor for signs of worsening, such as increased pain, redness, or fluid drainage, and seek medical attention if these occur.

13. Splinter Removal Aid

Baking soda can be an effective aid in the removal of small, shallow splinters by causing the skin to swell slightly, which may help push the splinter to the surface and make extraction easier. Unlike using tweezers or needles, which require direct manipulation and can be painful or risk infection if not properly sterilized, the baking soda method is less invasive and suitable for children or those with sensitive skin. To use, mix one-quarter teaspoon of baking soda with enough water to form a thick paste. Apply the paste directly over the area with the embedded splinter and cover with a clean adhesive bandage. After about 24 hours, remove the bandage and rinse the area. The splinter may have moved closer to the skin’s surface, making it easier to remove with sterilized tweezers if necessary. According to the American Academy of Dermatology, this method can be repeated if the splinter does not come out on the first attempt. However, if there is significant redness, swelling, pain, or if the splinter is deeply embedded, seek medical help to prevent infection or further injury.

14. Diaper Rash Relief

Baking soda’s gentle anti-irritant properties make it a useful home remedy for soothing mild diaper rash in babies. Its alkalinity can help neutralize acidic irritants in urine and stool, thereby reducing inflammation, redness, and discomfort. While zinc oxide creams remain the standard treatment—forming a protective barrier over the skin to prevent further irritation—baking soda can provide temporary relief, especially in between diaper changes or when commercial products are unavailable. For a soothing bath, dissolve two tablespoons of baking soda in a warm infant bathtub or a few inches of water in a regular tub, and allow the baby to soak for 10-15 minutes. After the bath, gently pat the skin dry and avoid rubbing to prevent further irritation. The American Academy of Pediatrics recommends gentle cleansing and air exposure for diaper rash, and baking soda baths may complement these practices. However, baking soda should not be applied directly to broken or oozing skin, and baths should be limited to avoid altering the skin’s natural balance. If the rash persists for more than a few days, worsens, or is accompanied by blisters or fever, consult a pediatrician promptly.

15. Chickenpox Itch Reduction

Baking soda baths are a well-established remedy for alleviating the intense itching associated with chickenpox, a highly contagious viral infection characterized by a widespread, blistering rash. Baking soda’s alkaline properties help to soothe inflamed skin and reduce irritation, providing temporary relief during the healing process. This approach is similar to oatmeal baths, which are also recommended for their anti-itch and moisturizing effects, but baking soda baths are particularly valued for their simplicity and accessibility. To prepare, add one cup of baking soda to a bathtub filled with lukewarm water and stir until dissolved. Soak the affected child or adult for 15-20 minutes, ensuring all areas of the rash are submerged. After bathing, gently pat the skin dry—avoid rubbing to prevent further irritation or blister rupture. The Centers for Disease Control and Prevention (CDC) recommends using soothing baths, such as those with baking soda or colloidal oatmeal, to manage chickenpox symptoms. While these baths help control itching, they do not speed up recovery or prevent complications. Persistent fever, signs of skin infection, or difficulty breathing require immediate medical evaluation. Baking soda baths are best used alongside other supportive care measures.

16. Urinary Tract Infection Symptom Relief

Baking soda may offer temporary relief from the burning sensation associated with urinary tract infections (UTIs) by alkalinizing the urine, which can help reduce acidity and irritation during urination. This home remedy involves dissolving half a teaspoon of baking soda in a glass of water and drinking it once or twice daily for a short period. In contrast, cranberry juice and supplements are more commonly used to prevent UTIs by inhibiting bacterial adhesion to the urinary tract lining, though evidence for their effectiveness is mixed. While baking soda may ease discomfort, it does not treat the underlying infection. The NHS and other health authorities strongly advise seeking medical attention for UTI symptoms, as untreated infections can lead to serious complications such as kidney infections. Frequent, painful urination, blood in the urine, fever, or back pain should never be ignored. Baking soda should not be used as a routine or long-term solution, especially for individuals with heart, kidney, or blood pressure issues, due to its high sodium content. Always consult a healthcare provider for proper diagnosis and treatment, as antibiotics are often required to clear UTIs safely.

17. Vaginal pH Balancing

Baking soda’s alkaline properties can help temporarily balance vaginal pH in cases of mild external irritation, such as itching or discomfort caused by minor pH fluctuations. By neutralizing excess acidity, baking soda may provide short-term relief for external vulvar symptoms. This approach differs from commercial feminine washes, which often contain fragrances, detergents, or antiseptics that may further disrupt the natural vaginal flora or cause irritation. To use, dissolve one to two tablespoons of baking soda in a basin of warm water and sit in the solution for 10-15 minutes as a sitz bath. This method can help soothe mild irritation but should not be performed more than a few times weekly. According to the American College of Obstetricians and Gynecologists (ACOG), the vagina is self-cleaning and routine use of douches or baking soda solutions internally is discouraged, as it can disrupt the natural balance and lead to infections. Persistent odor, itching, unusual discharge, or pain should always be evaluated by a healthcare provider to rule out infections or other underlying conditions. Baking soda sitz baths are best reserved for occasional, mild symptoms and never as a substitute for medical care.

18. Body Detox Bath

Body detox baths featuring baking soda have become increasingly popular in wellness circles, often touted as a way to “draw out toxins,” improve skin clarity, and promote relaxation. These baths typically involve dissolving half a cup to one cup of baking soda in a tub of warm water, sometimes combined with other ingredients like Epsom salt, essential oils, or apple cider vinegar. While Epsom salt (magnesium sulfate) is believed to soothe sore muscles and reduce inflammation, baking soda is claimed to help neutralize acids on the skin and support overall cleansing. However, scientific evidence supporting the concept of detoxification through topical baking soda baths is limited. According to the Healthline and the WebMD, the body’s primary detox organs are the liver and kidneys, which efficiently eliminate waste products without external assistance. Baking soda baths may provide a soothing, softening effect for the skin and can help relieve mild irritation or itching, but they do not “detox” the body in a medical sense. Individuals with sensitive skin or underlying health conditions should consult a physician before trying detox baths at home.

19. Nail Fungus Management

Baking soda’s mild antifungal properties make it a popular home remedy for managing nail fungus (onychomycosis), a common condition characterized by thick, discolored, or brittle nails. While not as potent as prescription antifungal lacquers or oral medications, baking soda can help control moisture and inhibit fungal growth, which thrives in damp environments. Prescription lacquers, such as ciclopirox or efinaconazole, penetrate the nail and directly target the fungus, offering higher cure rates but often requiring prolonged use and medical supervision. To use baking soda as a supportive measure, dissolve four to five tablespoons of baking soda in a basin of warm water and soak affected nails for 15-20 minutes daily. After soaking, thoroughly dry the nails, as moisture can worsen fungal infections. The American Academy of Dermatology notes that while home remedies like baking soda may provide minor symptom relief and help prevent recurrence, persistent nail fungus typically requires professional treatment for complete eradication. If nails become increasingly thickened, painful, or do not respond to home care, seek medical evaluation. Combining baking soda soaks with good foot hygiene can help limit the spread of nail fungus but is not a substitute for medical therapy.

20. Callus and Corn Softening

Baking soda can be an effective aid for softening calluses and corns, which are areas of thickened skin that develop in response to repeated friction or pressure—commonly on the feet or hands. Its mild alkalinity helps to break down and loosen the bonds between dead skin cells, making thickened areas easier to exfoliate. While pumice stones are a standard tool for physically removing calluses and corns after soaking, baking soda soaks can enhance the process by softening the skin beforehand and reducing discomfort during exfoliation. To use, dissolve three tablespoons of baking soda in a basin of warm water and soak the affected area for 15-20 minutes. After soaking, gently rub the callus or corn with a pumice stone or foot file to remove softened skin. The American Academy of Dermatology recommends regular soaking and gentle exfoliation as part of callus and corn management. However, individuals with diabetes or poor circulation should consult a healthcare provider before attempting home treatments, as they are at higher risk for complications. Baking soda soaks are best combined with proper footwear and protective padding to prevent recurrence.

Baking soda’s mild anti-inflammatory and soothing properties can offer relief for people experiencing eczema flare-ups, characterized by dry, red, and itchy patches of skin. By helping to neutralize skin acidity and reduce irritation, baking soda soaks may temporarily alleviate itching and discomfort. This approach is less potent than prescription creams—such as topical corticosteroids or calcineurin inhibitors—which directly target inflammation and immune responses. However, baking soda is a gentle home remedy suitable for mild symptoms or as a supplementary measure. To prepare a soothing bath, add one-quarter cup of baking soda to a tub of lukewarm water and soak for 10-15 minutes. After bathing, gently pat the skin dry and apply a fragrance-free moisturizer to lock in hydration. The National Eczema Association notes that while baking soda baths can help some individuals, others may experience irritation, so bath frequency and concentration should be adjusted according to individual tolerance. Avoid using hot water, as it can worsen eczema, and never apply baking soda directly to broken or severely inflamed skin. Persistent or severe eczema should be managed in consultation with a dermatologist for comprehensive care.

22. Psoriasis Symptom Relief

Baking soda baths may help relieve the discomfort associated with psoriasis, a chronic autoimmune condition that causes thick, scaly patches of inflamed skin. Baking soda’s alkaline properties can help reduce itchiness and soften scales, providing temporary respite from irritation. This method is gentler than coal tar baths, which are often prescribed for moderate to severe psoriasis due to their ability to slow skin cell growth and reduce scaling, but which can be messy, odorous, and sometimes irritating to sensitive skin. To use baking soda for psoriasis relief, add half a cup of baking soda to a lukewarm bath and soak for 15-20 minutes, ensuring affected areas are submerged. After the bath, gently pat the skin dry and apply a heavy, fragrance-free moisturizer to help retain moisture. The National Psoriasis Foundation recommends soothing baths, including those with baking soda, as a complementary strategy to ease symptoms between prescription treatments. However, baking soda should never be applied to cracked or bleeding plaques, and frequent use may lead to excessive dryness. Persistent or worsening symptoms should prompt consultation with a dermatologist for tailored medical management.

23. Dandruff Reduction

Baking soda is sometimes used as a natural remedy for dandruff due to its gentle antifungal and exfoliating properties. Dandruff, often caused by an overgrowth of the yeast Malassezia or buildup of dead skin cells, results in itching and flaking of the scalp. Baking soda can help by exfoliating dead skin and reducing fungal activity, thereby minimizing flakes and itchiness. In contrast, medicated shampoos—such as those containing zinc pyrithione, selenium sulfide, or ketoconazole—are specifically formulated to target the underlying fungal cause and provide more consistent, long-term relief. To use baking soda for dandruff, wet your hair and scalp thoroughly, then gently rub a small amount of baking soda (about one tablespoon) onto the scalp using your fingertips. Let it sit for 1-2 minutes before rinsing thoroughly with water. This method can be used 1-2 times per week, but overuse may dry out the scalp. The American Academy of Dermatology cautions that persistent or severe dandruff may require medicated treatments. If irritation, redness, or worsening symptoms occur, discontinue use and consult a dermatologist for personalized advice.

24. Hair Clarifying Rinse

Baking soda is a popular at-home solution for removing product buildup and excess oil from hair, thanks to its mild abrasive and alkaline properties. Over time, hair can accumulate residues from styling products, conditioners, and environmental pollutants, leading to dullness and heaviness. Baking soda acts as a clarifying agent by breaking down and lifting away these deposits. Compared to commercial clarifying shampoos, which may contain stronger detergents and are specifically formulated to deep-clean hair, baking soda offers a gentler and more affordable alternative, though it should be used sparingly to avoid over-drying the scalp and hair. To make a clarifying rinse, mix one tablespoon of baking soda with one cup of warm water and stir until dissolved. After wetting your hair, pour the solution over your scalp and hair, gently massaging it in for 1-2 minutes. Rinse thoroughly with water and follow with a conditioner to restore moisture. According to the American Academy of Dermatology, occasional clarifying treatments can help maintain healthy hair, but frequent use of strong cleansers or baking soda can cause dryness or irritation. Use baking soda rinses no more than once every two weeks for optimal results.

25. Oral Thrush Relief

Baking soda is sometimes recommended as a supportive home remedy for the relief of oral thrush, a common yeast infection caused by Candida species in the mouth. Its antifungal and pH-neutralizing properties can help create an environment less favorable for fungal growth, providing mild symptom relief. While prescription antifungal rinses or lozenges—such as nystatin or clotrimazole—are the standard treatment and directly target the pathogen, baking soda rinses may help reduce discomfort in mild cases or as an adjunct to medical therapy. To prepare a rinse, dissolve half a teaspoon of baking soda in one cup of warm water and swish the solution gently in the mouth for 30 seconds before spitting it out. This can be repeated several times daily. The Centers for Disease Control and Prevention (CDC) notes that while gentle rinses may help with symptoms, persistent or severe thrush requires professional evaluation and appropriate antifungal medications. Swallowing baking soda solution is not recommended, especially for young children or those with kidney or heart conditions. If white patches, soreness, or difficulty swallowing continue, seek prompt medical advice for targeted treatment.

26. Sore Throat Gargle

Baking soda gargles are a traditional remedy known for their soothing and anti-irritant effects on sore throats. The alkaline nature of baking soda helps neutralize acids in the throat, reduce inflammation, and create an environment less hospitable to bacteria and viruses. This can provide temporary relief from pain and scratchiness. While saltwater gargles are also widely recommended for sore throat relief due to their ability to draw out fluids and reduce swelling, baking soda offers an additional pH-balancing effect, and the two are often combined for enhanced benefit. To prepare a soothing gargle, mix one-quarter teaspoon of baking soda and one-quarter teaspoon of salt in a cup of warm water. Stir until dissolved, then gargle with the solution for 30 seconds before spitting it out. This can be repeated up to three times a day. The Mayo Clinic lists baking soda and saltwater gargles among simple home remedies for mild sore throats. However, persistent or severe symptoms—especially those accompanied by high fever, rash, or difficulty swallowing—require prompt medical evaluation to rule out strep throat or other serious conditions.

Baking soda is commonly included as an additive in nasal irrigation solutions to help relieve symptoms of sinus congestion, allergies, or sinusitis. Its alkaline properties work in tandem with saline to gently cleanse nasal passages, reduce irritation, and thin mucus. Compared to using saline alone, the addition of baking soda can further buffer the solution, making it less likely to sting sensitive nasal tissues and providing an added soothing effect. A typical homemade rinse involves mixing one quarter teaspoon of baking soda and one quarter teaspoon of non-iodized salt in one cup of distilled or previously boiled and cooled water. This solution can be used in a neti pot, squeeze bottle, or bulb syringe to irrigate the nasal passages. The American Academy of Otolaryngology-Head and Neck Surgery recommends this method for maintaining nasal health and providing symptom relief. It is essential to use only sterile or properly boiled water to avoid introducing harmful microorganisms into the sinuses. Sinus rinses should not be performed more than once or twice daily, and individuals with chronic nosebleeds or certain medical conditions should consult a physician before use. Discontinue if irritation or discomfort persists.

Baking soda rinses are a popular remedy for easing the discomfort of canker sores (aphthous ulcers) inside the mouth. Their effectiveness is attributed to baking soda’s ability to balance oral pH and neutralize acidic irritants, thereby reducing pain and promoting a less favorable environment for bacterial growth. This differs from benzocaine gels and other topical anesthetics, which provide direct numbing of the sore but do not address underlying acidity or oral hygiene. To make a soothing rinse, dissolve one teaspoon of baking soda in half a cup of warm water. Swish the solution in the mouth for 15-30 seconds, focusing on the affected area, then spit it out. This can be repeated up to four times daily as needed for relief. The American Dental Association acknowledges that baking soda rinses can help reduce irritation and keep the ulcer area clean. While these rinses can be very effective for mild or occasional sores, persistent, unusually large, or very painful canker sores may require evaluation and prescription medication. Avoid swallowing the rinse, and discontinue use if irritation or allergic reaction develops.

Baking soda is an effective solution for removing persistent odors from the hands after handling pungent foods such as garlic, onions, or fish. Its odor-absorbing and mildly abrasive properties help neutralize and lift away lingering compounds that water and regular soap may not completely remove. In comparison, lemon juice is often used for the same purpose due to its acidic content and fresh scent, but some individuals may find lemon juice irritating to sensitive or broken skin. To use baking soda for hand odor removal, simply wet your hands, sprinkle a teaspoon of baking soda onto your palms, and rub your hands together gently for 30-60 seconds, paying special attention to areas where odors tend to linger. Rinse thoroughly with warm water and dry your hands. The Cleveland Clinic notes that natural deodorizers like baking soda are a safe and non-irritating choice for most people. This method can be repeated as needed and is especially helpful after preparing meals with strongly scented ingredients. For those with sensitive skin, always rinse thoroughly and moisturize after washing to prevent dryness or irritation.

Baking soda is frequently used as a gentle exfoliant to help lighten dark underarms, a common cosmetic concern caused by the buildup of dead skin cells, friction, or irritation from shaving and deodorants. Its mild abrasive properties assist in removing surface debris, promoting smoother and brighter-looking skin over time. This approach is different from commercial creams, which may contain chemical exfoliants, bleaching agents, or fragrances that some people find harsh or irritating. To use, mix one tablespoon of baking soda with enough water to form a thick paste. Gently massage the paste onto clean, damp underarms in a circular motion for 30-60 seconds, then rinse thoroughly and pat dry. This process can be repeated two to three times per week but should not be done daily to avoid over-exfoliation and skin sensitivity. The Healthline editorial team notes that while baking soda may help with mild discoloration, results vary and persistent darkening could signal underlying medical issues, such as acanthosis nigricans, that require professional evaluation. Always discontinue use if irritation, redness, or itching occurs, and consult a dermatologist for persistent or unexplained skin changes.

31. Acne Spot Treatment

Baking soda is sometimes used as a home remedy for acne spot treatment due to its drying and mild anti-inflammatory properties. When applied directly to pimples, baking soda can help absorb excess oil and soothe localized redness or swelling. This approach is different from conventional acne treatments, such as salicylic acid or benzoyl peroxide, which are formulated to penetrate pores, reduce bacteria, and promote skin cell turnover for more targeted and sustained results. To use baking soda as a spot treatment, mix a small amount (about one teaspoon) with a few drops of water to form a thick paste. Dab the paste onto the affected area and leave it on for 5-10 minutes before rinsing thoroughly with lukewarm water. Because baking soda is alkaline, it can disrupt the skin’s protective acid mantle and lead to dryness, irritation, or even increased sensitivity if used too frequently or on large areas. The American Academy of Dermatology cautions against regular use of baking soda for acne, recommending evidence-based treatments for better safety and effectiveness. Discontinue use if irritation, burning, or worsening of acne occurs, and consult a dermatologist for chronic or severe acne.

32. Scalp Itch Soother

Baking soda’s anti-irritant and mild exfoliating properties can provide temporary relief for an itchy scalp, often caused by dryness, product buildup, or mild irritation. When used as a rinse, baking soda helps remove residues and soothe inflammation, offering a gentle alternative to medicated oils or shampoos. Medicated oils—such as those containing coal tar, salicylic acid, or tea tree oil—are typically formulated to address underlying scalp conditions like seborrheic dermatitis or psoriasis by reducing inflammation and controlling flaking, but they may sometimes be too strong for sensitive skin. To use baking soda as a scalp soother, mix one to two tablespoons of baking soda with one cup of warm water. After shampooing, pour the solution over the scalp, gently massaging it in for one to two minutes, then rinse thoroughly with water. This can be done once a week to avoid over-drying. The American Academy of Dermatology suggests that simple rinses like baking soda can help alleviate mild scalp irritation but emphasizes that persistent itching may indicate a medical condition. If symptoms continue, worsen, or are accompanied by flaking or sores, consult a dermatologist for targeted treatment.

33. Earwax Softener

Baking soda is occasionally used to soften earwax (cerumen) as part of a home remedy for managing mild ear blockage. Its alkaline properties help break down and loosen hardened wax, making it easier for the ear to expel naturally. This approach is similar to the use of olive oil or mineral oil drops, which lubricate and soften the wax but do not alter its pH. To use baking soda as an earwax softener, dissolve half a teaspoon of baking soda in two ounces (about 60 mL) of warm water. Using a clean dropper, place two to three drops of the solution into the affected ear while tilting the head to the side. Remain in this position for up to 10 minutes before allowing the liquid to drain out. This process can be repeated once daily for up to a week. According to the NHS, this method can be effective for mild cases, but it is crucial never to insert objects into the ear canal. If symptoms persist, worsen, or are accompanied by pain, hearing loss, or discharge, seek professional medical evaluation. Individuals with a history of ear surgery or eardrum perforation should avoid ear drops without consulting a healthcare provider.

34. Minor Wound Cleansing

Baking soda can be used as a gentle cleansing agent for minor wounds, such as small cuts, scrapes, or abrasions. Its mildly alkaline nature helps remove dirt and debris without causing the stinging or tissue irritation sometimes associated with stronger antiseptics. In contrast, hydrogen peroxide is often used for wound cleaning but can damage healthy cells and delay healing if overused. To cleanse a minor wound with baking soda, dissolve one teaspoon of baking soda in one cup of sterile or boiled and cooled water. Use a clean gauze pad or cotton ball to gently dab the solution onto the wound, rinsing away surface contaminants. According to the Mayo Clinic, the best wound care involves gentle cleaning, protecting the area with a sterile bandage, and monitoring for signs of infection such as redness, swelling, or pus. Baking soda should never be sprinkled directly onto open wounds or used on deep cuts, puncture wounds, or burns. If a wound does not begin to heal after a few days, or if there are signs of infection, seek medical attention promptly. Always wash hands before and after wound care to prevent contamination.

35. Bee Sting Neutralizer

Baking soda is commonly recommended as a home remedy for alleviating discomfort from bee stings, owing to its acid-neutralizing properties. Bee venom is slightly acidic, and applying a baking soda paste may help counteract this, reducing pain, swelling, and itching. This approach differs from the use of ice packs, which work primarily by constricting blood vessels, limiting inflammation, and providing numbing relief, but do not address the sting’s acidity. To use baking soda, mix one tablespoon of baking soda with just enough water to form a thick paste. Gently apply the paste to the affected area and let it sit for 15-20 minutes before rinsing off with cool water. This process can be repeated as needed for symptom relief. According to the American Academy of Dermatology, it is also important to remove the stinger as soon as possible and monitor for signs of a severe allergic reaction, such as difficulty breathing, swelling of the face or throat, or dizziness. For most mild stings, baking soda and ice packs can be used together, but seek emergency medical help if symptoms of anaphylaxis develop.

36. Razor Burn Relief

Baking soda offers a cooling and anti-itch effect that can help soothe razor burn, a common form of skin irritation resulting from shaving. Its alkaline nature helps calm inflammation and neutralize acids that may aggravate sensitive skin, providing temporary relief from redness, itching, and discomfort. Unlike commercial aftershave balms—which often contain moisturizers, antiseptics, or fragrances to hydrate and protect the skin—baking soda provides a fragrance-free, natural alternative, making it suitable for individuals with sensitive or allergy-prone skin. To use, dissolve one tablespoon of baking soda in one cup of cool water, then soak a clean washcloth or cotton pad in the solution. Gently apply the compress to the affected area for 5-10 minutes, repeating as needed. Avoid rubbing or scrubbing, which may worsen irritation. The American Academy of Dermatology suggests gentle, fragrance-free remedies for razor burn and cautions against products that may further irritate the skin. If razor burn is recurrent or develops into painful bumps or infection, consider reviewing your shaving technique or consulting a dermatologist. Always discontinue use if stinging or increased redness occurs.

37. Bug Bite Welts Reduction

Baking soda is a widely used home remedy for reducing swelling and itchiness associated with bug bite welts. Its mildly alkaline nature helps neutralize acidic irritants and calms the skin’s inflammatory response, providing temporary relief from discomfort. This contrasts with hydrocortisone creams, which deliver anti-inflammatory steroids directly to the bite area for more powerful and sustained reduction of swelling, redness, and itching. While hydrocortisone is often recommended for moderate to severe reactions, baking soda offers a gentle, non-pharmaceutical option for mild cases or for those with sensitive skin. To use, mix one tablespoon of baking soda with enough water to create a thick paste, then apply a small amount directly to the welt. Leave the paste on for 10-15 minutes before rinsing off with cool water. This process can be repeated up to three times daily as needed. The American Academy of Dermatology advises using cool compresses and soothing topical remedies like baking soda for mild insect bites. If swelling spreads, pain intensifies, or signs of allergic reaction (such as difficulty breathing or hives) develop, seek emergency medical attention promptly.

38. Blister Drying

Baking soda can be used to help dry and soothe minor blisters, particularly those caused by friction or mild burns. Its mildly alkaline and drying properties assist in reducing moisture around the blister, which may prevent further irritation and help the area heal more comfortably. This approach is different from using moleskin, a soft, adhesive padding designed to protect the blister from additional friction and pressure but does not address moisture or aid drying. To use baking soda for blister care, mix one teaspoon of baking soda with a small amount of water to form a thick paste. Gently apply the paste to the intact blister and allow it to sit for 10-15 minutes before rinsing off with cool water. This process can be repeated once or twice daily as needed. According to the Mayo Clinic, blisters should be kept clean and protected, and the skin should not be punctured unless medically necessary, as the outer layer serves as a natural barrier against infection. If a blister becomes very painful, shows signs of infection, or does not improve, seek medical advice for further evaluation and care.

39. Cold Sore Discomfort Reduction

Baking soda is sometimes used as a home remedy to reduce the discomfort associated with cold sores, which are caused by the herpes simplex virus. Its mild alkalinity and soothing properties can help dry out the sore, reduce irritation, and provide temporary relief from itching and pain. This approach differs from antiviral creams, such as those containing acyclovir or docosanol, which are clinically proven to shorten the duration and severity of outbreaks by directly inhibiting viral replication. To use baking soda, mix a small amount with water to form a thick paste, then dab it gently onto the cold sore with a clean cotton swab. Leave it on for 5-10 minutes before rinsing off with water. This process can be repeated up to three times daily as needed. According to the American Academy of Dermatology, while soothing remedies like baking soda may provide symptomatic relief, they do not address the underlying viral infection or prevent recurrence. If cold sores are frequent, severe, or accompanied by fever or widespread symptoms, consult a healthcare professional for appropriate antiviral treatment and care advice.

40. Minor Itch Relief (Chlorinated Pools)

Baking soda is a helpful remedy for easing minor skin irritation and itching that can occur after swimming in chlorinated pools. Chlorine can disrupt the natural oils and pH balance of the skin, leading to dryness, irritation, and itching—sometimes referred to as “chlorine rash.” Baking soda’s alkalinity helps neutralize residual chlorine and calms irritated skin. This approach is similar to oatmeal baths, which are also widely recommended for their soothing and anti-itch benefits, especially in cases of sensitive skin. To use baking soda, add half a cup to a bathtub filled with lukewarm water and soak for 15-20 minutes after swimming. Gently pat the skin dry afterward and apply a fragrance-free moisturizer to help restore hydration. The American Academy of Dermatology suggests baking soda and oatmeal baths as effective ways to relieve dry, itchy skin from environmental irritants like chlorine. Avoid hot water, which can worsen dryness, and limit bath time for children. If irritation persists, is severe, or is accompanied by a rash, consult a dermatologist for further advice and tailored care.

41. Deodorizing Medical Devices

Baking soda is an effective, gentle option for deodorizing medical devices that come into contact with the mouth or face, such as braces, retainers, dentures, or CPAP (Continuous Positive Airway Pressure) masks. Its mild abrasive and odor-neutralizing properties help remove food particles, saliva, and bacteria that can lead to unpleasant smells. Unlike some commercial cleansers, which may contain strong chemicals or artificial fragrances, baking soda is less likely to cause irritation or leave behind residues that could be inhaled or ingested. To clean these devices, dissolve one to two teaspoons of baking soda in a cup of warm water and soak the device for 15-30 minutes. For devices like retainers or dentures, a soft toothbrush can be used to gently scrub all surfaces before rinsing thoroughly with clean water. For CPAP masks, soak only the non-electronic, non-fabric components, then rinse and air dry completely before reassembly. The Sleep Foundation and American Association of Orthodontists recommend baking soda as a safe cleaning alternative. Regular cleaning prevents odor and extends device longevity. For stubborn stains or buildup, periodic use of commercial cleansers may be necessary.

42. Cleaning Hearing Aids

Baking soda offers a gentle and safe option for cleaning certain parts of hearing aids, particularly earmolds and tubing, which can accumulate earwax, sweat, and oils. Unlike alcohol wipes, which can be too harsh and may degrade plastics or damage sensitive electronics, baking soda is non-abrasive and does not leave behind harmful residues. To clean hearing aid earmolds, first detach them from the electronic components according to the manufacturer’s instructions. Dissolve one teaspoon of baking soda in a cup of warm water and soak the earmolds and tubing for 10-15 minutes. After soaking, use a soft brush to remove any remaining debris, rinse thoroughly with clean water, and allow the parts to air dry completely before reattaching to the device. Never submerge the electronic portion of the hearing aid or use baking soda directly on those components. The American Speech-Language-Hearing Association (ASHA) recommends regular cleaning of hearing aid parts to ensure optimal performance and comfort. For daily cleaning of the device exterior, a soft, dry cloth is preferable. If you have concerns about buildup or malfunction, consult your audiologist or hearing aid specialist for professional cleaning and maintenance.

Baking soda is a practical solution for removing odors and residues from orthopedic braces, splints, and supports, which can accumulate sweat, oils, and bacteria through regular use. Its gentle abrasive and deodorizing properties make it effective for cleaning without damaging materials such as plastic, silicone, or fabric linings. While soap and water are commonly used for cleaning these devices, baking soda offers an additional odor-neutralizing benefit and may be less likely to leave behind soapy residues that could irritate the skin. To clean an orthopedic brace or splint, dissolve two tablespoons of baking soda in a basin of warm water. Remove any detachable liners or straps and soak them in the solution for 15-20 minutes. Use a soft brush or cloth to gently scrub surfaces, paying attention to areas with visible buildup. Rinse thoroughly with clean water and allow all components to air dry completely before reassembling and wearing. The Verywell Health editorial team recommends gentle cleaning methods for maintaining hygiene and comfort. Always check manufacturer guidelines before cleaning, as certain materials may require special care or avoid soaking. For persistent odors or stains, consult your provider for further advice.

Baking soda is frequently recommended as an effective treatment for minor jellyfish stings due to its ability to neutralize nematocysts—the tiny, venom-containing cells that continue to fire after contact. A baking soda slurry (a mixture of baking soda and seawater) can help deactivate undischarged nematocysts, reducing pain and preventing further venom release. In comparison, vinegar is also commonly advised for certain jellyfish species, particularly box jellyfish, as it can inactivate nematocysts but may worsen stings from other species. To use baking soda for a sting, mix equal parts baking soda and seawater to form a paste and gently apply it to the affected area for 15-20 minutes. Rinse with seawater (never fresh water, which can trigger more nematocysts to fire) and carefully remove any tentacles with tweezers or gloved hands. The British Red Cross and CDC recommend seeking emergency medical attention if a sting causes severe pain, difficulty breathing, chest tightness, or involves a large area of the body. Always be aware of local jellyfish warnings and follow medical advice for unfamiliar or severe reactions.

Baking soda is an effective and affordable option for removing odors and residues from CPAP (Continuous Positive Airway Pressure) masks, which are used by individuals managing sleep apnea. Over time, these masks can accumulate oils, sweat, and bacteria, leading to unpleasant smells and potential skin irritation. Baking soda’s gentle abrasive and deodorizing qualities help remove buildup without damaging delicate mask materials. Compared to commercial CPAP cleaning wipes, which offer convenience and often contain mild detergents or disinfectants, baking soda is a fragrance-free alternative that can be especially suitable for users with sensitive skin. To clean a CPAP mask, first detach any electronic or fabric components. Dissolve one to two teaspoons of baking soda in a bowl of warm water and soak the mask and tubing for 15-30 minutes. Use a soft cloth or brush to gently clean crevices, then rinse thoroughly with clean water and allow all parts to air dry before reassembly. The Sleep Foundation recommends regular cleaning of CPAP equipment to prevent bacterial growth and maintain device performance. Avoid using harsh chemicals or excessive force, as these can damage the mask’s seal and affect therapy effectiveness.

Baking soda can provide temporary relief from the itching and burning associated with hemorrhoids, which are swollen blood vessels in the rectal or anal area. Its natural alkalinity helps neutralize acids on irritated skin, reducing discomfort and providing a soothing effect. This approach offers a gentle, fragrance-free alternative to witch hazel pads, which are widely used for their astringent and anti-inflammatory properties but may cause stinging in some individuals. A common method of using baking soda for hemorrhoid relief is through a sitz bath: dissolve two to four tablespoons of baking soda in a few inches of warm water in a sitz bath basin or regular bathtub. Soak the affected area for 15-20 minutes, then gently pat dry. Sitz baths can be repeated several times a day, especially after bowel movements, to alleviate symptoms. The Mayo Clinic recommends sitz baths as part of a comprehensive hemorrhoid care routine. If symptoms persist, worsen, or are accompanied by significant bleeding, seek medical advice to rule out more serious conditions and receive appropriate treatment. Baking soda is best used as a supportive measure for mild to moderate discomfort.

47. Odor Control in Wound Dressings

Baking soda is valued for its natural deodorizing properties and can be used to help control unpleasant odors in wound dressings, particularly for chronic wounds or ulcers that may develop a malodor due to bacterial activity. By neutralizing acidic byproducts, baking soda can help create a less hospitable environment for odor-causing bacteria. This approach is less sophisticated than the use of charcoal dressings, which are specifically designed to absorb both moisture and odors and are often used in medical settings for wounds with heavy exudate. To use baking soda at home, a small amount can be lightly sprinkled onto a gauze pad before applying the dressing, or a thin layer can be placed under the bandage—ensuring it does not come in direct contact with the wound itself to avoid irritation. The Wounds International resource highlights the importance of odor control for patient comfort and quality of life. However, persistent wound odor may indicate infection or poor wound healing and should be evaluated by a healthcare professional. Charcoal or antimicrobial dressings may be more effective for complex wounds, and all dressing changes should be performed with clean hands and sterile supplies.

Baking soda can be used externally as a gentle cleanser for irritated eyelids, such as in cases of blepharitis or after exposure to allergens. Its mild alkalinity helps remove debris, oil, and flakes from the eyelid margins, promoting cleanliness and reducing irritation. This method is different from using sterile saline, which is preferred for rinsing the eye itself and for direct ocular irrigation, as saline matches the eye’s natural salt balance and is less likely to cause stinging or disruption. To cleanse the eyelids, dissolve one-eighth teaspoon of baking soda in one cup of boiled and cooled water. Dip a clean cotton pad or swab into the solution and gently wipe along the closed eyelids and lash line, avoiding any contact with the eye surface. Repeat as needed, using a fresh applicator for each eye to prevent cross-contamination. The American Academy of Ophthalmology recommends lid scrubs for eyelid hygiene but stresses the importance of never introducing baking soda directly into the eye, as it may cause significant irritation or harm. Persistent redness, swelling, or pain should prompt consultation with an eye care professional.

After proper rewarming of minor frostbite, baking soda may offer soothing relief for post-thawing skin discomfort due to its mild anti-irritant and alkalinizing properties. When applied as a cool compress, baking soda can help calm itching, burning, and mild inflammation that often follows thawing of affected skin. This approach is somewhat similar to using aloe vera gel, which is favored for its cooling, moisturizing, and anti-inflammatory effects, but baking soda is particularly valued for its accessibility and gentle cleansing action. To use, dissolve one to two teaspoons of baking soda in a cup of cool (not cold or icy) water. Soak a clean cloth in the solution and gently apply it as a compress to the thawed area for 10-15 minutes. Do not rub or massage the skin, as this can worsen tissue damage. According to the Centers for Disease Control and Prevention (CDC), all cases of frostbite—no matter how minor—should be evaluated by a healthcare professional to assess tissue injury and prevent complications. Baking soda compresses are for supportive care only; persistent numbness, blistering, or severe pain require urgent medical attention.

Baking soda is a popular home remedy for calming mild allergic skin reactions, such as localized rashes, hives, or itching caused by contact with allergens like plants, detergents, or certain foods. Its mild alkalinity helps neutralize irritants on the skin and provides a soothing, anti-itch effect, which can offer temporary comfort while the reaction resolves. In contrast, antihistamine lotions or creams (like those containing diphenhydramine) work by blocking histamine—the chemical responsible for allergic symptoms—and may provide stronger, longer-lasting relief but sometimes cause drowsiness or skin sensitivity. To use baking soda safely, mix one to two tablespoons with enough water to create a thick paste, then gently apply it to the affected area for 10-15 minutes before rinsing off with cool water. Alternatively, add half a cup of baking soda to a lukewarm bath for widespread reactions. The American Academy of Dermatology recommends simple home remedies like baking soda for mild rashes, but warns that persistent, spreading, or severe symptoms (such as swelling of the face or difficulty breathing) require immediate medical attention. Discontinue use if irritation worsens, and always avoid applying to broken or oozing skin.
