20 Unbelievable Baking Soda Uses

2. Insect Bites and Poison Ivy

Baking soda can help calm itchy skin caused by insect bites and poison ivy. It works by drying irritated areas and helping reduce the urge to scratch, which can prevent further skin damage. This simple approach is commonly used for mild skin reactions.

To treat a mosquito or insect bite, combine 1 tablespoon of baking soda with a little water to make a thick paste. Apply the paste directly to the bite and leave it on for about 10 minutes before rinsing it off. If itching continues, you can repeat this method a few times a day. Avoid scratching the area, since broken skin can increase the risk of infection. In some cases, an antihistamine cream or anti-itch cream may also help ease discomfort.

Poison ivy causes a rash when plant oil comes into contact with the skin. The affected area may itch, swell, and develop small blisters. After washing the skin with soap and water to remove any remaining plant oil, apply the same baking soda paste to the rash to help soothe irritation. For larger areas of irritation, adding 1 cup of baking soda to a lukewarm bath can help calm widespread itching.

3. Heartburn, Indigestion, and Ulcer Pain

Heartburn and indigestion often develop after large meals or foods that stimulate acid production, including fatty or spicy dishes. Drinks containing caffeine can also trigger symptoms. When too much acid builds up in the stomach, it can irritate the upper digestive tract and cause a burning feeling in the chest or upper abdomen.

Baking soda can be used as a quick, short-term remedy for these symptoms. It is alkaline, which means it can help neutralize excess stomach acid. This temporary reduction in acid may ease symptoms such as bloating, a sour taste in the mouth, or mild stomach discomfort. To use it, mix 1/2 teaspoon of baking soda in a full glass of water and drink it slowly.

Ulcers are open sores that form in the lining of the stomach or small intestine. They can cause a dull or burning pain in the upper abdomen. Because baking soda can briefly reduce stomach acid, it may provide short-term relief from ulcer-related discomfort.

4. Foot Soak and Exfoliator

Sweat and bacteria often collect on the feet during the day, which can lead to odor and buildup on the skin. Baking soda can help freshen and smooth the feet because it loosens dirt, softens thick skin, and helps reduce odor. This makes it a useful option after long periods of standing or walking.

To make a basic foot soak, fill a basin with warm water and add 2 to 3 tablespoons of baking soda. Stir until it dissolves, then soak your feet for 15 to 20 minutes. Warm water softens the skin, while baking soda helps lift away surface buildup. After soaking, pat your feet dry, especially between your toes. You can also turn baking soda into a gentle exfoliator.

Mix 1 tablespoon of baking soda with a small amount of water to form a paste. Rub it on rough areas such as the heels and the balls of your feet using small, circular motions to help remove dead skin. Rinse well and dry your feet completely.

5. Relaxing Soak

You can turn a simple bath into a calming soak with baking soda. Baking soda dissolves easily in warm water and is alkaline, which means it can help balance acids on the skin surface. This may leave the skin feeling smoother and help ease mild skin discomfort.

To prepare the soak, add 1/2 to 1 cup of baking soda to a full bathtub of warm water. Swirl the water with your hand to help it dissolve, then soak for about 15 to 20 minutes. Warm water helps relax the body while the dissolved baking soda spreads evenly across the skin. This bath can relieve dry or itchy skin, minor rashes, sunburned skin, and general body tension.

After soaking, rinse off with clean water and gently pat your skin dry. You can also use baking soda for a relaxing foot soak. Fill a basin with warm water and mix in 2 to 3 tablespoons of baking soda. Soak your feet for about 15 minutes to help soften rough skin and reduce odor.

6. Hand Cleanser

You can use baking soda as a simple hand cleanser when your hands feel greasy or dirty. Its fine grains act as a mild scrub that helps loosen dirt and buildup from the skin without being too rough. To use it, mix a small amount of baking soda with water to form a paste.

Rub the paste over your hands, including between your fingers and around your nails, then rinse well with clean, running water. You can also combine baking soda with a few drops of liquid hand soap. The soap helps wash away oils and germs, while the baking soda helps lift stubborn residue and strong food odors, such as those from onions, garlic, or fish.

Regular handwashing plays an important role in limiting the spread of germs. Wash your hands before eating, after using the bathroom, and after touching shared surfaces. Scrub for at least 20 seconds, then rinse and dry with a clean towel or air dryer. If soap and water are not available, use a hand sanitizer that contains at least 60 percent alcohol.

7. Splinter Removal

A small splinter can cause steady discomfort and skin irritation. Baking soda may help draw the splinter closer to the surface, which can make removal easier. Begin by washing your hands with soap and water, then clean the skin around the splinter the same way to reduce the chance of infection.

Next, mix a small amount of baking soda with a few drops of water until it forms a thick paste. Spread the paste over the splinter and cover the area with a clean bandage. Leave the bandage in place for several hours or overnight. Baking soda may cause the surrounding skin to swell slightly, which can push the splinter closer to the outer layer of the skin. After removing the bandage, examine the area carefully.

If the splinter is visible, use clean tweezers to pull it out at the same angle it entered. If necessary, gently lift the tip with a sterilized needle before removing it with tweezers. Once the splinter is removed, wash the area again with soap and water. Pat the skin dry and cover it with a fresh bandage if the area is open or likely to become dirty.

8. Sunburn Remedy

You can use baking soda to help soothe mild sunburn and ease skin discomfort. Sunburn occurs when excessive ultraviolet light damages the outer layers of the skin. The affected area may feel warm, sore, or tight, and peeling may occur after a few days as the skin heals.

One simple method is a baking soda bath. Add 1/4 to 1/2 cup of baking soda to a lukewarm bath and soak for about 15 to 20 minutes. The cool water helps lower skin temperature, while baking soda may help calm surface irritation. After soaking, gently pat your skin dry rather than rubbing to avoid further irritation.

You can also prepare baking soda paste. Mix a small amount of baking soda with water to form a soft paste, then spread a thin layer over the affected skin. Let it sit for about 10 to 15 minutes before rinsing with cool water and patting the skin dry. Baking soda may help reduce redness and itching because of its mild soothing properties.

9. Whiten Teeth

Baking soda can help remove surface stains from your teeth. As a mild abrasive, it gently scrubs away stains caused by substances like coffee, tea, or tobacco. While it doesn’t change the natural color of your teeth, it can make them appear brighter.

To use it, mix a small amount of baking soda with water to form a thick paste. Dip your toothbrush into the paste and brush gently for about two minutes, then rinse your mouth well with water. Since baking soda is abrasive, it should only be used a few times per week.

Brushing too often with baking soda can wear down enamel, the protective outer layer of your teeth, which can lead to tooth sensitivity and other dental issues. Some toothpastes also contain baking soda. These products are formulated to gently remove stains while including ingredients like fluoride, which helps strengthen enamel and protect your teeth against cavities.

10. Polish the Silverware

You can restore dull silverware with baking soda and a few simple tools. Tarnish forms when silver reacts with sulfur in the air, creating a dark layer on the surface. Baking soda helps remove this tarnish through a simple chemical reaction.

To begin, line a bowl or sink with aluminum foil, shiny side up. Place the silverware on the foil so each piece touches it. Sprinkle baking soda over the items, then pour hot water into the container until everything is covered. Small bubbles will begin to form as the reaction starts. During this process, the tarnish transfers from the silver to the aluminum foil.

Let the silverware sit in the solution for about five to ten minutes. After soaking, remove the pieces and rinse them with clean water. Dry each item with a soft cloth to prevent water spots and restore the shine. For lighter tarnish, you can also make a paste by mixing baking soda with a small amount of water. Rub the paste gently onto the silver using a soft cloth, then rinse and dry well.

11. Clean Produce

You can use baking soda to help clean fresh fruits and vegetables before you eat them. While rinsing with water removes some dirt, baking soda can help loosen surface residue and wax that plain water may leave behind.

To prepare the solution, fill a large bowl with water and add about 1 teaspoon of baking soda for every 2 cups of water. Stir until the baking soda dissolves. Place the produce in the bowl and let it soak for about 10 to 15 minutes. This soaking step helps loosen residue and debris on the surface. After soaking, gently rub the produce with your hands or use a soft brush.

This works especially well for firm items such as apples, cucumbers, and potatoes. For leafy greens, separate the leaves before soaking them in the baking soda solution. This allows the water to reach areas where dirt may collect in folds and creases.

12. Clean Carpet Stains

You can use baking soda to help lift common carpet stains and reduce odors. It works best on fresh spills, but it may also improve older spots because baking soda absorbs moisture and odor particles from the carpet fibers. Start by blotting the stain with a clean cloth. Avoid rubbing the area, since rubbing can push the stain deeper into the fibers.

Once the area is slightly damp, sprinkle a thick layer of baking soda over the spot. Let the baking soda sit for at least 15 minutes so it can absorb moisture and odors. For stronger smells or darker stains, leaving it overnight may produce better results. After the baking soda dries, vacuum the area slowly and thoroughly. This removes the baking soda along with the moisture and residue it absorbed, leaving the carpet cleaner and fresher.

For tougher stains such as juice, coffee, or pet accidents, mix baking soda with a small amount of water to form a paste. Spread the paste over the stain and allow it to dry completely. Once it hardens, vacuum the remaining residue.

13. Kitchen Cleaner

Baking soda is a simple and effective kitchen cleaner. Its mild grit helps scrub away dirt, grease, and food stains from many hard surfaces without scratching most countertops and sinks. To clean surfaces, sprinkle baking soda directly on the sink, stovetop, or counter.

Add a small amount of water to form a thick paste, then scrub with a sponge or cloth. Rinse with warm water and wipe the surface dry. For greasy spots on the stove or range hood, mix baking soda with a few drops of dish soap to form a paste.

Let it sit for 10 to 15 minutes to loosen the stuck-on grease. Then, scrub lightly and wipe the area clean. Baking soda can also help lift remaining residue before disinfecting if needed. To freshen kitchen drains, pour about half a cup of baking soda down the drain, followed by hot water.

14. Improve Exercise Performance

You can use baking soda to support short, high-intensity workouts. Baking soda is sodium bicarbonate, which acts as a buffer that helps balance acid levels in the muscles during intense effort. During activities such as sprinting, heavy weightlifting, or high-intensity intervals, the body produces acid as muscles work harder.

As this acid builds up, muscles may begin to feel tired or weak. Sodium bicarbonate may help reduce this buildup, which can delay fatigue during brief, intense activity. Some athletes mix a small amount of baking soda in water and drink it about 60 to 90 minutes before exercise. Research suggests it may improve performance in activities such as sprinting, rowing, or other short bursts that last a few minutes.

For this reason, it is best to start with a very small amount to see how your body responds. Avoid using baking soda for performance if you need to limit sodium or if you have kidney, heart, or blood pressure conditions.

15. Calm Canker Sores With Baking Soda Mouthwash

Canker sores are small, painful ulcers that can develop inside the mouth. They may appear on the tongue, inner cheeks, or gums. Baking soda may help soothe this irritation because it helps balance the acid levels in the mouth and may reduce swelling around the sore.

These effects can ease discomfort and support the natural healing process. To make a simple baking soda mouthwash, mix 1 teaspoon of baking soda with 1 cup of warm water and stir until it fully dissolves. Swish the mixture in your mouth for about 15 to 30 seconds, then spit it out. This can be repeated once or twice a day.

You can also make a paste by mixing a small amount of baking soda with a few drops of water. Apply the paste gently to the sore and let it sit for a few minutes before rinsing your mouth. While the sore heals, it may help to avoid spicy, salty, or acidic foods that can irritate the area.

16. Clean Your Bathtub

You can use baking soda to clean your bathtub with simple steps and low cost. Baking soda helps lift dirt, soap scum, and light stains because its mild grit provides gentle scrubbing power without producing harsh fumes. Start by rinsing the tub with warm water to loosen surface dirt and soften dried soap residue.

Next, sprinkle a thick layer of baking soda over the wet surface, focusing on areas that appear stained or dull. Let the baking soda sit for about 10 to 15 minutes so it can loosen grime. Afterward, scrub the surface with a damp sponge or soft brush using firm, even pressure.

Rinse the tub well with warm water to wash away the loosened residue. For tougher spots, mix baking soda with a small amount of water to form a paste. Spread the paste over the stain, let it sit briefly, then scrub again before rinsing thoroughly.

17. Clean Brushes and Combs

Hairbrushes and combs collect oil, dead skin, and hair products during daily use. Over time, this buildup can transfer back onto clean hair. Baking soda helps loosen and lift this residue, making the tools easier to clean. Start by removing any loose hair from the brush or comb.

Fill a bowl with warm water and add 1 to 2 teaspoons of baking soda, stirring until it dissolves. Place plastic brushes and combs in the bowl and allow them to soak for about 15 to 30 minutes. This helps loosen oil and dirt that collect between the bristles.

Avoid soaking wooden brushes, since water can damage the handle. After soaking, scrub between the bristles with an old toothbrush to remove remaining residue. Rinse thoroughly under clean running water and allow the brush or comb to air dry completely before using it again. For heavier buildup, mix baking soda with a small amount of water to form a paste.

18. Homemade Air Freshener

You can use baking soda to freshen the air in your home without strong chemicals. Baking soda works by absorbing odor molecules rather than covering them up, which makes it useful in small rooms, closets, and cars. To make a simple air freshener, fill a small jar halfway with baking soda.

Add about 10 to 15 drops of your preferred essential oil and stir the mixture well. Cover the jar with breathable fabric or paper with small holes so the scent can slowly release into the air. Place the jar in areas with stale odors, like bathrooms, near trash cans, or inside shoe cabinets.

As the jar sits, the baking soda gradually absorbs unwanted smells while the essential oil adds a light fragrance. Shake the jar every few days to refresh the scent and expose fresh baking soda to the air. Replace the mixture about once a month or when the scent fades.

19. Natural Drain Cleaner

You can clear minor clogs in your sink without using harsh chemicals. Baking soda can help loosen grease, soap residue, and light debris that often cause slow drains. Start by pouring about half a cup of baking soda directly into the drain, then follow with one cup of white vinegar.

The mixture will fizz as the reaction begins, helping break apart buildup inside the pipe. Let the mixture sit for about 10 to 15 minutes so the reaction can loosen debris that sticks to the pipe walls. After waiting, pour a kettle of hot water down the drain. The hot water helps flush away the loosened residue and move it through the pipe.

Run tap water for about a minute afterward to check that the drain flows more smoothly. This method works best for minor clogs. If water does not drain at all or if you suspect a more serious blockage, you may need a plunger or professional assistance.

20. Deodorize Cat Litter and Absorb Toilet Odors

You can use baking soda to manage odors in areas where waste smells collect quickly, especially around litter boxes and toilets. Its mild odor-absorbing action helps reduce unwanted smells and keeps enclosed spaces smelling fresher between regular cleaning. For a litter box, sprinkle a thin layer of baking soda across the bottom before adding fresh litter.

You may also mix a small amount into the litter during changes to help limit odor as the litter is used. Clean the litter box regularly and disinfect it as part of normal care, since baking soda helps with odor but does not replace proper cleaning.

You can also freshen the toilet by adding about half a cup of baking soda directly into the bowl. Let it sit for 10 to 15 minutes before flushing so it has time to absorb lingering smells. For continued odor control, keep a small open container of baking soda near the toilet and replace it about once a month
