Baking soda is one of the handiest things to keep in a kitchen cupboard. ๐ง
Its proper name is sodium bicarbonate, a mild alkaline powder that can neutralise acids and soak up smells.
That simple chemistry is why it cleans, freshens, and deodorises so well around the home.
This guide keeps only the household uses that are safe and easy to picture. ๐

Do not swallow baking soda as a remedy. If you have heartburn, stomach pain, or any health concern, ask a pharmacist or clinician instead of mixing up a home drink.
Keep it away from children in quantity. A small amount in baking is normal, but a box left where children can scoop from it is not safe.
Test a small area first. Baking soda is mildly gritty, so try a hidden spot before scrubbing a whole surface, especially on polished or delicate finishes.
Never mix baking soda with vinegar in a sealed container. The fizz builds up gas and pressure, and a closed bottle or jar can burst.
One more caution: baking soda is not a disinfectant on its own, so do not rely on it to sanitise surfaces that need proper disinfecting.
1. Kitchen Cleaning ๐ณ
Microwave: Wipe the inside with a damp sponge sprinkled with baking soda, then rinse with clean water.

5. Cooking and Food Prep ๐ฅฆ
Baking: Baking soda is a raising agent that reacts with acidic ingredients, such as lemon juice or buttermilk, to help batters rise.
Washing fruit and vegetables: Soak produce in a bowl of water with about a teaspoon of baking soda per two cups of water for 12 to 15 minutes, then rinse well.
That soak cut surface residues in a laboratory study of apples, but it cannot remove anything that has already soaked into the fruit itself.
Peeling is still the surest way to remove residues from the skin, even though you lose some nutrients with the peel.

6. Polishing and Small Household Jobs โจ

Combs and brushes: Soak them in warm baking soda water to loosen styling-product build-up, then rinse and dry.
Furniture marks: Rub light marks gently with baking soda on a damp sponge, then wipe with a clean, dry cloth.
7. Outdoors and the Garage ๐
Oil and grease on driveways: Sprinkle baking soda over the stain, scrub with a wet brush, and rinse with water.
Weeds on paths: Sprinkle baking soda over weeds growing in cracks in paths and driveways only, never on flower beds or lawns, where it can harm the plants you want.
A note on small pan fires: Baking soda gives off carbon dioxide when heated, which is why it is sometimes thrown at very small cooking fires, but only if it is safe to do so, and the fire service should still be called.
Never use water on a grease fire, and never try to fight a fire that is growing or spreading.
Frequently Asked Questions โ
Is baking soda the same as baking powder? No. Baking soda is pure sodium bicarbonate, while baking powder already contains an acid, so they are not interchangeable in recipes.
Can I use baking soda on every surface? No. Skip it on delicate stone, polished wood, and non-stick coatings unless the maker says it is safe, and always test first.
Does baking soda remove smells or just cover them? It reacts with many acidic smell molecules, which is why it neutralises odours instead of masking them with fragrance.
How long does an open box last in the fridge? About a month, after which it loses strength, so mark the date when you open it.
