Growing up, I remember we always had baking soda on hand for leavening biscuits, dumplings, and various quick breads. Mom set an open box into the fridge to absorb odors and had us drink a bit of it in water to ease upset stomachs.

In recent years, I’ve found more uses for it. Like many of you, during the COVID-19 quarantine, I learned to get by with fewer household items in general, discovering new uses for ordinary things that were readily available and never in short supply.

Keep an open box of baking soda in the refrigerator to absorb any escaping smells so other foods won’t. Exchange for a new box whenever you clean the fridge. Use the contents of the old box for scrubbing jobs.

One rule of thumb: Baking soda is excellent at removing grease, grime, scum, and stinky smells just about everywhere.

Best Uses for Baking Soda

In the Bathroom

• Clean toilet bowls: Add a quarter cup of baking soda and half a cup of white vinegar to an empty bowl. Bubbles will form! Scrub with a stiff brush and flush. Repeat if necessary. A damp cloth sprinkled with baking soda will also clean the outside surfaces of the toilet, tank, and cover.
• Clean faucets and door handles: Make a thick paste of baking soda and a bit of water, apply to grimy areas, and scrub with a stiff brush (For the tightest spots, I use an old toothbrush. I save all my toothbrushes for tasks like this). Rinse off immediately, or let it dry and rinse later.
• Clean toothbrushes: Soak toothbrushes in baking soda and warm water overnight to clean bristles.
• Clean rubber gloves: Keep your rubber gloves dry and smelling good by sprinkling baking soda inside them. They’ll slip on more easily, too!
• Unclog drains: Pour a cup of baking soda into the opening of your clogged drain, and then add a cup of hot vinegar. After a few minutes, flush the drain with a quart of boiling water.

In the Kitchen

• Scrub coffee mugs, tea cups, and carafes: Sprinkle the inside of the mug or container with baking soda and gently scrub with a moist cloth to remove the stains. Then, give the mug or container a thorough rinse.
• Remove burned-on foods from stainless steel cookware: Add plenty of baking soda to the pot/pan with enough water to form a thick slurry, let sit (minutes, hours, or overnight), and scour with a fresh scrubbing pad. Repeat as necessary.
• Clean your refrigerator: Scrub with a solution of 1 teaspoon baking soda to 1 quart of warm water.
• Clean your toaster oven: Sprinkle 1 teaspoon of baking soda on the bottom of your toaster oven to eliminate the burned smell from drippings and crumbs.
• Clean fresh produce: To remove pesticides, dirt, and wax from fresh fruit and vegetables, wash them in a large bowl of cool water to which you’ve added 2 to 3 tablespoons of baking soda.
• Get red sauce stains out: A paste of baking soda removes red sauce stains from plastic.
• Unclog drains: Pour a cup of baking soda into the opening of your clogged drain, and then add a cup of hot vinegar. After a few minutes, flush the drain with a quart of boiling water.

Cooking and Baking

• Make fluffier omelets: A pinch (¼ teaspoon or less) in your morning eggs as you whip them up will make your omelets or scrambled eggs fluffier.
• Make the best cookies: In a project intended to find the best leavening agent for chocolate-chip cookies, the folks at BuzzFeed baked 400 cookies comparing various agents and discovered that baking-soda-only cookies won hands down. Prove them wrong!
• Prevent syrup from crystallizing: Add a pinch of baking soda to boiled syrup to keep it in liquid form.

For Health

• Clean teeth: The antibacterial properties of baking soda help reduce bacterial plaques that cause tooth decay and gum disease, while its mild abrasive quality helps remove light staining. Mix a little baking soda with a few drops of water to make a thick paste. Wet your brush and coat teeth with paste, brush gently, and rinse well.
• Soothe a sunburn: Add baking soda to your bath water to relieve sunburned or itchy skin.
• Ease an insect bite: Make a paste of baking soda and water, and apply it to a burn or an insect bite for relief.
• Stop the craving: If you crave sweets, rinse your mouth with 1 teaspoon baking soda dissolved in a glass of warm water. Don’t swallow the mixture; spit it out. Your craving should disappear instantly.
• Freshen breath: For freshening breath, add a spoonful of baking soda to a glass of warm water (or peppermint tea), and swoosh the mixture around in your mouth for 30 seconds or more before spitting it out. 
• Ease occasional heartburn/indigestion: The standard dose for this old-fashioned remedy is 1/2 teaspoon of baking soda in 1/2 cup of water. If you have frequent heartburn or other digestive problems, consult a doctor.

On Clothing

• Remove sweat stains: To remove perspiration stains, make a thick paste of baking soda and water. Rub paste into the stain, let it sit for an hour, and then launder as usual. Find out how to remove other common stains.
• Get rid of odors: Gasoline and oil odors can be removed by putting clothes in a trash bag with baking soda for a few days before washing them.
• Remove odors from smelly shoes: Liberally sprinkle baking soda inside the shoes (and under the inserts, too). Place shoes in a large paper bag and leave overnight. When you’re ready to put on your shoes, shake out the soda. 
• Remove stains on hat bands: Mix a quarter cup of white vinegar with a tablespoon of liquid detergent and spray on the hat and brim. Then sprinkle baking soda liberally on the hat and brim and scrub in. Let the hat sit for up to an hour and then spray with vinegar mixture and give the stain another scrub. Rinse in cold water. Pat dry with a towel and allow the hat to air-dry completely.
• Clean a steam iron: When the ironing surface (soleplate) gets grubby, scrub it gently with a paste of baking soda and water. Let it dry before removing with a soft brush. If that doesn’t quite do the trick, soak a small towel or washcloth in white vinegar, lay it on newspapers on the ironing board, and sprinkle baking soda on the towel. Then, “iron” the towel back and forth without plugging the iron in. 

For Your Dog

• Freshen up your smelly dog: Liberally sprinkle your smelly dog (outdoors, if possible) with baking soda, avoiding the face. Massage it in well so it coats the skin, and leave it for a few minutes to absorb the offending odors. Then, give your dog a good brushing. 
• Additional advantages of a baking soda bath: It imparts luster to the coat, soothes a dog’s skin, and kills fleas and other parasites.

In the Car

• Deodorize your car (or trunk): Freshen your car by sprinkling baking soda on the upholstery and floor mats. Let it sit for a few hours before vacuuming, removing any extra baking soda with a damp cloth. Some people keep their ashtrays filled with baking soda. 
• Remove bugs and tar: A light baking soda paste on a damp cloth will remove bugs and tar from cars without damaging the paint. Let the paste sit for a few minutes before wiping and rinsing clean.

Miscellaneous Uses

• Deodorize stinky hands: After cutting fish or handling other smelly items, dust your hands well with baking soda and scrub them under running warm water for a few seconds.
• Freshen trash bins: Just add a sprinkle of baking soda to the inside of your kitchen and bathroom trash cans, or inside the trash bags themselves. Once a year, I take mine outside and scrub with a little liquid detergent and a strong spray of the garden hose.
• Stop the bad bugs: Lay down a barrier of baking soda under sink-pipe openings and along basement windows to keep carpenter ants, silverfish, and roaches from invading. Roaches eat the baking soda, dehydrate, and die.
• Melt ice: Sprinkling baking soda on your front steps will provide traction and melt the ice. Unlike rock salt, kitty litter, or sand, it won’t damage outdoor or indoor surfaces or shoes.

NOTE: Don’t use baking soda to clean glass surfaces, silverware, stone countertops, wooden floors, or furniture. Dermatologists also warn against using baking soda routinely as dry shampoo or underarm deodorant because its alkalinity will disrupt the natural acidity of the skin and scalp.
