Baking soda, or sodium bicarbonate, is one of the most versatile products you can keep at home. While it’s often used as a leavening agent in baking, it also happens to be a powerhouse cleaning ingredient. Non-toxic, inexpensive, and effective, baking soda can tackle dirt, grease, stains, and odors in almost every room of the house — and even outdoors.
Unlike many commercial cleaners, baking soda doesn’t rely on harsh chemicals, synthetic fragrances, or corrosive ingredients. Instead, it works by neutralizing acids, dissolving grease, scrubbing gently without scratching, and absorbing odors. This makes it a safe and eco-friendly alternative for families, pet owners, and anyone who wants a more natural approach to cleaning.
This comprehensive guide explains exactly how you can use baking soda to keep your home fresh and spotless. We’ll cover the kitchen, bathroom, living room, bedroom, laundry, and even outdoor spaces, with clear instructions and tips on avoiding common mistakes.
Why Baking Soda Works

The secret behind baking soda’s cleaning power lies in its chemistry and physical properties:
-
Mild alkali: Baking soda reacts with acidic substances like grease, grime, and food spills, breaking them down so they can be wiped away.
-
Gentle abrasiveness: Its fine grains scrub away dirt and residue without scratching most surfaces.
-
Natural deodorizer: It neutralizes odors instead of just covering them up, making spaces smell genuinely fresh.
-
Safe and eco-friendly: Baking soda is non-toxic, biodegradable, and septic-safe.
It is important to note, however, that baking soda is not a disinfectant. While it cleans and deodorizes, it doesn’t reliably kill bacteria or viruses. For full sanitization, you may need to combine it with vinegar, hydrogen peroxide, or another approved disinfectant.
Cleaning with Baking Soda: Room by Room
Kitchen

The kitchen is one of the busiest parts of the home — and one of the dirtiest. From greasy stovetops to smelly fridges, baking soda provides safe, effective, and affordable cleaning solutions.
1. Deep-cleaning the oven
Commercial oven cleaners are often strong-smelling and corrosive. Baking soda offers a safer option.
-
Remove racks and trays.
-
Mix baking soda with water until it forms a thick paste.
-
Spread the paste across the oven’s walls and floor (avoid heating elements).
-
Leave overnight, then wipe off with a damp cloth.
-
Spray with vinegar, let it fizz, and wipe again for extra shine.
-
Clean racks separately by sprinkling with baking soda, spraying vinegar, and soaking in hot water before scrubbing.
2. Degreasing stovetops and cooktops
Sprinkle baking soda on the surface, spray with hot water, and leave for 20–30 minutes. Scrub gently to remove stubborn grease without scratching.
3. Freshening the microwave
Soak a sponge in warm water and dip it in baking soda. Wipe the microwave’s interior and exterior thoroughly, then rinse. For stuck-on food, place a bowl of baking soda solution inside, run the microwave until it steams, let sit, then wipe clean.
4. Cleaning the refrigerator
Place an open pot or jar of baking soda in the fridge to absorb odors. Stir occasionally and replace every few weeks. You can also wipe shelves with a damp cloth dipped in baking soda solution for a deeper clean.
5. Dishwasher care
Sprinkle a generous amount of baking soda into the empty dishwasher and run it on the hottest cycle. This freshens and deodorizes the appliance. You can also add two tablespoons alongside dish detergent to boost cleaning power for greasy loads.
6. Countertops and sinks
Make a paste of baking soda and water, apply to stained areas, scrub gently, and rinse. For tougher stains on granite or marble, apply the paste, leave for 24 hours, then wipe away.
7. Cutting boards and utensils
Sprinkle baking soda on boards or utensils, scrub with a sponge, and rinse. It removes odors without leaving a chemical taste.
8. Trash bins
Deodorize kitchen bins by sprinkling baking soda directly into the base. For a deep clean, rinse the bin, scrub with baking soda paste, and rinse again.
9. Fruits and vegetables
Soak produce in a baking soda solution to remove pesticides, dirt, and wax without harsh chemicals.
Bathroom

Bathrooms collect soap scum, mildew, mineral deposits, and odors. Baking soda’s abrasiveness and deodorizing qualities make it ideal for nearly every surface.
10. Tile grout
Mix three parts baking soda with one part water to make a paste. Apply to grout lines, let sit for 5–10 minutes, scrub with a toothbrush, and rinse. For extra whitening, mix with hydrogen peroxide instead of water.
11. Tiles and shower walls
Sprinkle baking soda on a damp sponge and scrub surfaces. For stubborn film, spray vinegar over the baking soda layer and wipe after fizzing.
12. Toilet bowl cleaning
For routine cleaning, sprinkle baking soda into the bowl, let sit 10 minutes, scrub, and flush. For deep cleaning, add vinegar for fizzing action that loosens stains and odors.
13. Toilet tank maintenance
Turn off the water supply and flush to empty the tank. Sprinkle baking soda inside, let sit 30 minutes, scrub, refill, and flush. Adding vinegar before baking soda helps dissolve mineral buildup. Avoid bleach tablets, which corrode parts.
14. Clearing minor toilet clogs
Pour one cup of baking soda into the bowl, followed by one gallon of hot (not boiling) water. Wait 30 minutes, then flush. Adding dish soap before the water improves results.
15. Showerheads and faucets
Wrap the fixture with a vinegar-soaked cloth for 15 minutes, then scrub with baking soda for a polished finish.
16. Removing rust stains
Pour vinegar and baking soda onto stains in the sink, shower, or toilet, scrub, and rinse.
17. Freshening drains
Pour half a cup of baking soda down the drain, followed by half a cup of vinegar. Let fizz 10 minutes, then flush with boiling water.
Living Room

Living rooms may not seem as messy as kitchens or bathrooms, but carpets, upholstery, and air often need deodorizing.
18. Carpets
Sprinkle baking soda across the carpet, leave overnight, then vacuum. It absorbs odors and freshens fibers. For stains, rub baking soda into the spot with a damp cloth, let sit for an hour, then scrub and vacuum.
19. Upholstery and sofas
Sprinkle a light layer of baking soda, let sit 15 minutes, and vacuum. This is safe for most fabrics and removes odors.
20. Mattresses
Sprinkle baking soda over the mattress, leave several hours, then vacuum. It neutralizes odors from sweat and dust mites.
21. Walls and furniture
Apply baking soda to a damp sponge and rub gently to remove mildew, stains, or crayon marks.
22. Air freshening
Fill a jar with baking soda, add a few drops of essential oil, and cover with breathable fabric. Place in the room to absorb odors naturally.

Common Mistakes to Avoid
While baking soda is safe and versatile, it does have limits:
-
Do not use on marble, polished granite, or aluminum, as it can scratch or dull the surface.
-
Always rinse surfaces thoroughly to avoid leaving a chalky residue.
-
Do not rely solely on baking soda and vinegar for heavy clogs; the fizz is temporary and won’t break through tough blockages.
-
Avoid over-diluting baking soda — paste form is most effective for scrubbing.
