In this article, we’ll explore 17 smart baking soda tips—divided between kitchen uses and gardening hacks—that will help you clean, cook, and grow smarter.
What Is Baking Soda?
Baking soda is a naturally occurring compound made of sodium, hydrogen, carbon, and oxygen.
It’s alkaline, slightly abrasive, and reacts with acids, which makes it useful for cleaning, deodorizing, neutralizing pH, and pest control.
Let’s start with how to use baking soda in the kitchen, then move into the garden.
9 Smart Baking Soda Tips for the Kitchen
1. Natural All-Purpose Cleaner
Mix baking soda with water to form a paste and use it as a scrub for sinks, countertops, and stovetops.
It’s abrasive enough to remove grime but gentle enough not to scratch most surfaces.
How to use:
-
3 tablespoons baking soda
-
1 tablespoon water
Mix and apply with a sponge or cloth.
2. Neutralize Fridge Odors
Baking soda is famous for absorbing odors in the refrigerator. It neutralizes acidic and basic molecules that cause bad smells.
Tip: Place an open box or small bowl of baking soda in the back of your fridge and replace every 2–3 months.
3. Clean Produce Naturally
Use baking soda as a safe, non-toxic way to clean fruits and vegetables by removing dirt, pesticides, and wax.
How to use:
-
Fill a bowl with water
-
Add 1 teaspoon of baking soda

Soak produce for 10–15 minutes and rinse
4. Boost Dishwasher Detergent
Add a spoonful of baking soda to your dishwasher detergent to help cut grease, boost cleaning power, and prevent spots on dishes.
How to use: Add 1 tablespoon of baking soda along with your usual detergent.
5. Deodorize Cutting Boards and Sponges
Cutting boards and kitchen sponges can hold onto odors and bacteria. Sprinkle with baking soda and scrub gently to deodorize and disinfect.
Tip: You can also soak sponges in a solution of baking soda and warm water overnight.
6. Fire Extinguisher for Grease Fires
Baking soda can act as a mini fire extinguisher for small grease fires on the stove. It releases carbon dioxide when heated, which smothers flames.
Important: Only use for small flare-ups, and never throw water on a grease fire.
7. Clean Burnt Pots and Pans
Baking soda works wonders on stubborn, burnt-on food in pots and pans.
How to use:
-
Sprinkle baking soda generously over the pan
-
Add hot water and let it sit overnight

How to use: Mix 1 tablespoon of baking soda with a few drops of water, scrub gently, and rinse well.
9. Tenderize Meat Naturally
Because of its alkalinity, baking soda can help break down proteins in meat, making it more tender.
How to use:

Rub 1 teaspoon of baking soda per pound of meat
-
Let sit for 15–20 minutes, then rinse thoroughly before cooking

How to use: Sprinkle dry baking soda directly into the cracks where weeds grow. The salt-like texture can dehydrate weed roots.

Add 1 tablespoon of baking soda to a cup of soil + water mixture
-
If it fizzes, your soil is likely acidic
