40 Brilliant Uses For Baking Soda That Might Surprise You

When you think of baking soda, you likely think of, well, baking! This kitchen cupboard staple has a lot more uses than just helping your baked goods rise, however. There are so many uses for baking soda both in and out of the kitchen. Here are a few of our favorites.


40 Uses For Baking Soda That You Probably Didn’t Know About

The uses for baking soda are practically endless. It can be used for cleaning, baking, as a natural part of your personal hygiene routine – the list goes on and on. Many of us, however, don’t know about all of the incredible ways you can use this everyday item. We’ve rounded about 40 of them to get you started on using this inexpensive, natural item in as many ways as possible.


1. Keep Flowers Fresh

We love cut flowers just as much as anyone else. A vase full of brightly colored fauna can brighten up any room and put a smile on a sad face. The sad day is when the flowers start to droop, lose their vibrancy, and eventually need to be tossed away. Thankfully, baking soda can help to keep your flowers kicking a little bit longer. Put a teaspoon of the powder into a vase of water, making sure that there are no leaves or petals in the water. It’s best practice to change the water daily.


2. Dry Shampoo

Dry shampoo is expensive but is a godsend when you just don’t have time to wash your hair. Unfortunately, it can be quite expensive. Yet again, baking soda is here to save the day! Sprinkle some into the roots of your hair and gently rub in. The baking soda will absorb some of the excess oil and help you go a little longer between wash days. Be careful not to do this too often, however, so you don’t dry out your scalp and cause breakage.


3. A Teeth Whitener

Due to its pH and gently abrasive nature, baking soda is effective at removing plaque and whitening your teeth. The simplest way is, after brushing with regular toothpaste, to brush your teeth with a baking soda-water mixture. Leave it on for two minutes and then rinse thoroughly with water.


4. De-Ordorize Your Garbage Bins

Often even after emptying and rinsing our trash cans, they still smell. All you have to do is sprinkle a decent amount (say, a half-cup) of baking soda into the bottom of the bin and continue to use as normal. The baking soda will neutralize the odor.


5. A Fruit and Veggie Wash

One of my favorite uses for baking soda! Baking soda is a highly effective way to wash your fruits and veggies, especially when trying to remove any harmful chemicals that may or may not be on them. Fill a clean bowl or cleaned and sanitized sink with cold water. Add one teaspoon of baking soda for every two cups of water. Submerge the produce and let them soak for 12 to 15 minutes swishing them around occasionally. Make sure you dry them thoroughly before preparing or storing them.


6. Clean Your Car Batteries

Too much build-up on your car engine can significantly shorten your car’s battery life. To clean it, first, disconnect the battery. Then, mix six heaping tablespoons of baking soda with four cups of water. Using an old toothbrush or rag, rub on the paste and scrape off any deposits. Rinse with water, making sure no water gets into the vents.


7. Help With Heartburn

Baking soda is a natural antacid. It can absorb stomach acid and temporarily relieve acid reflux. If this is a recurring problem for you, make sure you visit your doctor to see what more can be done. For adults and teenagers, dissolve half a teaspoon in a four-ounce glass of water. Repeat no more than every two hours. Too much baking soda can cause acid rebound and make the problem worse.


8. Bug Bite Relief

Summer is wonderful – backyard barbecues, bonfires, camping, and cottages. What’s not wonderful? Mosquito bites. To relieve the itchiness, mix one tablespoon of baking soda with just enough water to make a paste. Put the paste on your bites and let it sit for 10 minutes before washing it off.


9. Foot Odor

Sometimes feet just stink. To deodorize them, soak your feet in a bucket with water and baking soda. Use one tablespoon of baking soda for one quart of water and soak for 15 minutes. If it’s your shoes that are the problem, simply sprinkle some baking soda inside them and let it absorb overnight.

Another one of my favorite uses for baking soda! Outdoor patio furniture tends to get dirtier than our indoor furniture. This is especially true after it’s been sitting in your shed for several months during winter. To effectively clean it without scratches, sprinkle baking soda on a wet sponge. From there, wipe down all your furniture.

12. Heal Sores

Canker sores or mouth ulcers are annoying and painful. Thankfully, baking soda is an effective natural remedy for them by restoring the pH of your mouth and reducing the inflammation around the sore. Dissolve one teaspoon of baking soda in a half-cup of water, swish it around your mouth for 10-15 seconds, then spit it out. You can repeat this every few hours or so, as needed.

13. Deodorize Your Fridge

Stuffed animals are tough to clean and often full of dust and oils. To clean them, cover the entire surface of the toy in baking soda and put it in a plastic bag or pillowcase. Shake vigorously for a few minutes. Let them sit for one to one and a half hours for the baking soda to absorb all of the oils. You can do multiple at once. After waiting. shake off the excess baking soda and toss the pillowcase with stuffed animals inside it into the dryer to clean and fluff them up more.

15. Razor Burn Relief

For those of us who prefer to shave, razor burn can be a hard-fought battle. Those little red bumps are not only taking away from the smooth skin we imagined, but they’re uncomfortable, too. To relieve it, mix one cup of water with one tablespoon of baking soda and apply to the affected areas with a cotton pad. When the mixture is dry, rinse it off. Repeat twice daily. Alternatively, you can soak in a lukewarm bath with one cup of baking soda in it.

16. Clean Shower Curtains

Shower curtains can be absolutely disgusting. They get wet all the time without being left open properly enough to dry, and are tough to clean. To clean, sprinkle baking soda on a damp, microfiber cloth and scrub the entire curtain. Rinse with another clean, damp cloth to remove all the baking soda. Repeat as necessary.

17. Weed Killer

No one likes weeds sticking up through the cracks of their patio. To kill a weed in your garden, first wet the weed a bit with the hose. Then sprinkle one teaspoon of baking soda on the entire weed. This will ensure you kill the weed and nothing else. For the cracks in the pavement, generously sprinkle baking soda on top of the weeds growing out of them. Reapply every four to six weeks if the weeds aren’t completely gone. This method works best in the spring or fall when the weeds are actively growing.

18. Clean Carpet Stains

What can’t baking soda do? For non-greasy carpet stains, sprinkle baking soda generously over the entire stain. Using a spray bottle, mist the stain with hot water. Keep the area damp and allow to sit for at least three hours. You can do this by leaving a damp cloth over the stain so you don’t have to keep misting it. Afterward, vacuum up the leftover baking soda.

For greasy stains, start by blotting the area with a wet rag or paper towel first to remove as much of the grease as possible. Next, sprinkle dry baking soda on the stain and allow it to sit overnight. Vacuum up the excess baking soda in the morning.

19. Put Out Small Cooking Fires

Maybe the most important on this list of uses for baking soda. You can put out small cooking fires that involve oil and grease using baking soda. Pouring baking soda on the fire will smother it and choke it out. Remember, this only works for small fires. Make sure you still have a fire extinguisher on hand for larger ones or in case this doesn’t fully put out the fire.

Having a shelf full of old books is incredible – there’s nothing quite like the smell of an old, well-loved novel.

For any book that is starting to smell less like nostalgia and more just plain old, sprinkle some baking soda between its pages. It will smell like new in no time!

28. Wall Cleaner

Baking soda and vinegar can work wonders for a clogged drain. This works particularly well if it is your kitchen sink and there is an oil or grease build-up. Start by pouring boiling water down the drain. Next, pour down a solution made of one cup of baking soda, one cup of hot water, and one cup of vinegar. Cover with the drain plug and wait five to 10 minutes. It will bubble up a lot – don’t worry, it’s supposed to! This is the baking soda and vinegar working against the clog. Finish by pouring more boiling water down the drain.

Note that this will not work if the clog is a hair clog. For that, you will need to buy a special drain cleaner specifically for hair.

32. Sunburn Relief

Baking soda has a one-two punch when it comes to cleaning plastic containers. First of all, it removes the food stains. Second, it removes the smell.

34. Clean Sponges

Our fur babies are adorable, but let’s be honest: Sometimes, they stink! Don’t let their bed (or other soft surfaces that they may sleep on) stink up your house. First, vacuum off the hair and other particles that may be on the bed. Second, fill up a basin with warm water and about one-quarter cup of baking soda. Put soak the removable cover in this for about 15 minutes. If the bed doesn’t have a removable cover (or fido prefers the couch), sprinkle baking soda over the area for 15 minutes and then vacuum off to alleviate the odor.

It is highly important that you are regularly cleaning and disinfecting your retainer. After all, you’re wearing it in your mouth every single day!

A true grill master also knows how to properly clean their grill. Make a paste using one and a half cups of baking soda and a half cup of water.

Using an aluminum foil ball, scrub the grates clean. Rinse with water and put the grates back in the grill.

38. Remove Bathroom Wall Mildew

Let it sit for 10 minutes, then scrub off with a brush and rinse well.

39. Grease Stains
