36 Clever and Frugal Uses for Baking Soda (Not Just for Baking!)

You’ll find it in small boxes in the supermarket aisle next to flour, sugar, and cake mixes. It comes in 10-lb. bags at Costco, shelved next to the pancake and waffle mix. It’s a key ingredient in light, fluffy biscuits. But baking soda is not just for baking.

What is baking soda, anyway?

Sodium bicarbonate, commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation and a bicarbonate anion. This simple chemical compound is found in nature, harvested, and ground to a fine powder for household use.

What does baking soda do?

Baking soda is an alkaline compound that produces harmless, albeit useful, carbon dioxide gas when combined with acid. When used to bake biscuits or cake, the small bubbles of carbon dioxide gas become trapped in the batter, causing it to inflate or rise.

Baking soda is well known for its ability to absorb odors. This is why many people place a box of baking soda in refrigerators, freezers, and other enclosed spaces to absorb random odors.

Baking soda is also an ideal cleaner because of its granular texture, which helps with scrubbing. Its alkaline pH can dissolve some deposits and build-up.

1. Natural deodorant

If you are allergic to commercial deodorants or prefer to stay away from aluminum and parabens found in many antiperspirants, you might want to consider making it yourself.

Deodorant Paste

Mix about 1/4 tspn baking soda with a very small amount of lukewarm water in a bowl until it forms a thick paste. Gently apply the paste to your underarms using your fingertips. Allow the paste is completely dry before getting dressed.

Deodorant Spray

You will need:

✅  1/2 teaspoon baking soda
✅  1/2 cup witch hazel (100% natural astringent)
✅  1/4 cup aloe vera gel
✅  spray bottle


Place all ingredients in a spray bottle. Shake well to mix. Apply lightly as you would any commercial spray deodorant.

Witch hazel and aloe vera gel are found at grocery stores, health food stores, also online.

2. Poison ivy, insect bites

Got camping on your mind? Then you need to know about this super effective, cheap, and easy way to deal with the true bane of every camper’s existence—insect bites and poison ivy!

Baking soda can these issues while out in nature. Mix up a baking soda and water paste and apply it to the site of the bite or irritation and watch as the pain slowly dissipates until it finally disappears completely.

Baking soda relieves itching and irritation on your skin because it neutralizes toxins that may be sitting on the surface.

3. Heartburn, indigestion

Most antacids available over the counter contain one type or another of bicarbonate. Baking soda, sodium bicarbonate, is effective because it neutralizes the stomach acid instantly on contact to relieve ulcer pain, indigestion, heartburn, and myriad issues resulting from an overly abundant amount of acid in your gut.

Typically, the recommended dosage when using baking soda to treat gastrointestinal issues is 1/2 tsp baking soda that has been dissolved in a 1/4 cup of water.

4. Foot soak, exfoliator

A foot bath or soak is definitely one of the most relaxing experiences out there. If you want to make it even more awesome, add baking soda to your routine. Fill your basin or foot spa with warm water as you normally do, but this time add three tablespoons of baking soda.

A paste made of 1 part baking soda to 3 parts water makes for a very effective foot exfoliator.

7. Freshen up smelly shoes

Use baking soda to absorb and eliminate odor from stinky shoes. Sprinkle a generous amount of baking soda into the shoes, making sure it is distributed well.

8. Head off garbage can odors

You can prevent odors from building up in your kitchen garbage and bathroom trash cans with the help of baking soda. Just sprinkle a small amount right into the container over the trash or garbage from time to time.

I like to use baking soda in my kitty litter box! I buy a good Arm & Hammer brand of clumping litter, but I still don’t want to have the occasional whiff. So, when scooping the cat waste out every other day I add a 1/2 cup of baking soda. No one can smell that I have a cat. Regina

20. Costume jewelry cleaner

I am NOT recommending this for anything other than costume jewelry (although I do use it on sterling silver). I have zero resources; this is just something I heard YEARS ago and have always done it!

Place just a few pieces of jewelry in a very small bowl, sprinkle baking soda over them, and then add vinegar just a tablespoon or two at a time, so it will fizz and then slow down (I do this several times). It’s fun to do when the grandkids are around! I only let it sit for about five minutes and then wipe dry with a paper towel and then I use the Norwex microfiber cloth. Comes out very shiny and clean! Tracy

This is how I “marinate” my boneless skinless chicken breast pieces so they don’t turn dry and hard when stir frying or baking. Just mix chicken pieces with a teaspoon of baking soda and let sit in the fridge for about 20 minutes. It’s called “velveting.” Apparently Chinese food restaurants do this. I tend to overcook chicken “just in case” and this keeps it from drying out. Sue

25. Fresh ‘n clean dishcloths

To clean my dishcloths, I load them into the washing machine, sprinkle baking soda over the cloths, use hot water and soak them 30 minutes to an hour. Rinse and spin (only because my washer will not immediately wash after the soak cycle), and then wash with regular detergent in hot water. My dishcloths no longer have that yucky, musty odor but smell nice and fresh! Irene

26. Clean glass bakeware

I was looking up the recipe to make homemade pretzels and the last step before baking is to use a lye solution as a final dip for the dough. Working with lye is difficult, so people have suggested baking soda. The problem is baking soda does not give the best result. Solution? If baking soda is baked itself first before making the solution, the result increases the alkalinity of the baking soda and gives a better result for the pretzels. Gina

29. Deep-clean teeth

When we were younger, and if we ran out of toothpaste, my mom would put some baking soda in a dish, and we would dip our damp toothbrush in and use that. It actually doesn’t taste too bad, and our teeth felt so clean and smooth. I still sometimes do that. Betty

33. Hair rid

I use baking soda mixed in with my shampoo to remove build-up from the conditioner and other hair products. I keep an old Parmesan cheese container with baking soda in it in the shower (great big shaker holes) and just sprinkle it in my hand with the shampoo about every other week or as needed. My hair is squeaky clean afterward! Tammy Jo

    If you have burned-on food on the floor of your oven, cover it with a thick layer of baking soda. Sprinkle on water until it’s damp, but not too soupy. Let sit overnight. The next morning it wipes right off. No chemical smell from oven cleaners, either.
