Baking Soda Cleaning: Uses You Didn’t Know

Baking soda (sodium bicarbonate) is a useful, inexpensive, and non-toxic cleaning product that many households already have in the pantry. While it won’t replace every cleaning product you own, it handles a surprisingly wide range of tasks — from scrubbing ovens to deodorizing carpets.

Here are 12 surprising ways to use baking soda for cleaning — most of which you probably haven’t tried.

1. Clean Your Oven (Without Harsh Chemicals)

The oven is one of the hardest things to clean, but baking soda can make the job more manageable.

1. Remove oven racks and set aside.
2. Mix baking soda with water to form a thick paste (about 3 parts baking soda to 1 part water).
3. Spread the paste all over the interior of the oven, avoiding the heating elements.
4. Let it sit overnight (at least 12 hours).
5. Wipe clean with a damp cloth the next day.
6. For stubborn spots, spray with vinegar — it will fizz, then wipe clean.
7. Clean the racks separately in the bathtub with hot water and baking soda.

2. Unclog Drains

Baking soda and vinegar is a popular, gentle approach for minor drain maintenance.

1. Pour 1/2 cup of baking soda down the drain.
2. Follow with 1/2 cup of white vinegar.
3. Cover the drain and wait 15-30 minutes.
4. Flush with boiling water.
5. For tough clogs, repeat or let the baking soda sit longer.

This can help with minor clogs and is gentler on pipes than chemical drain cleaners. For severe or recurring clogs, a plunger or professional plumbing service may be needed.

⚠️ Never pour boiling water down PVC or plastic pipes. Many modern sink drains and the traps under them are PVC or other plastic, which can soften, warp, or crack under boiling water — potentially causing a leak or burst pipe. Use hot tap water instead of boiling water. If you’re unsure what your drain pipes are made of, play it safe and skip the boiling water.

3. Freshen Carpets and Remove Stains

Baking soda can help lift stains and deodorize carpets.

1. Blot the stain with a clean cloth (don’t rub).
2. Sprinkle baking soda generously over the stain.
3. Let it sit for 15-30 minutes (or overnight for tough stains).
4. Vacuum thoroughly.
5. For greasy stains, mix baking soda with a small amount of dish soap and apply as a paste first.

4. Clean Grout Between Tiles

Grout gets dirty and discolored over time.

1. Make a paste of baking soda and water.
2. Apply to grout lines with an old toothbrush.
3. Spray with vinegar for extra cleaning power.
4. Scrub and rinse with clean water.
5. This often helps brighten discolored grout, though results vary depending on how set-in the stains are.

5. Freshen Your Mattress

Mattresses absorb sweat, dust, and odors over time.

1. Strip the bed and vacuum the mattress.
2. Sprinkle baking soda generously over the entire surface.
3. Add a few drops of lavender essential oil for a fresh scent (optional).
4. Let it sit for at least 1 hour (overnight is better).
5. Vacuum thoroughly with an upholstery attachment.

6. Clean Stainless Steel Appliances

Baking soda can help remove fingerprints and streaks from stainless steel.

1. Sprinkle baking soda on a damp soft cloth.
2. Gently wipe in the direction of the grain.
3. Rinse with a clean damp cloth.
4. Dry with a microfiber cloth to prevent streaks.

7. Deodorize Your Refrigerator

An open box of baking soda in the fridge is classic for a reason.

1. Place an open box of baking soda on a shelf.
2. Replace it every 30 days.
3. For stronger odors, sprinkle baking soda on a plate and leave overnight.
4. To clean the interior: wipe shelves with a solution of 2 tablespoons baking soda per quart of warm water.

8. Clean the Microwave

Steam with baking soda can help loosen hardened food residue.

1. Mix 2 tablespoons of baking soda with 1 cup of water in a microwave-safe bowl.
2. Microwave for 5 minutes until it boils and steams.
3. Leave the door closed for 3 more minutes (the steam loosens grime).
4. Wipe clean with a cloth — the steam should loosen most of the residue.

⚠️ Superheating hazard: When heating plain water in a microwave, it can become superheated — hotter than its boiling point — and erupt violently when disturbed or moved, causing serious burns. To reduce the risk: use a microwave-safe container with a lip or handle, stir the liquid before and after heating, and avoid heating pure water for long periods without interruption. Don’t leave the microwave unattended while it’s running.

9. Remove Clothing Stains

Baking soda helps lift stains from fabric.

• Sweat stains: Make a paste of baking soda and water, apply to the stain, let sit for 30 minutes, then wash.
• Grease stains: Sprinkle baking soda on fresh grease to absorb it, then brush off and wash.
• Blood stains: Soak in cold water with baking soda, then wash in cold water.

10. Clean and Deodorize Trash Cans

1. Sprinkle baking soda in the bottom of an empty trash can.
2. Let it sit for a few hours to absorb odors.
3. Wash with hot soapy water, then rinse.
4. Place a small box of baking soda at the bottom under the bag.

11. Polish Silver Jewelry

1. Line a bowl with aluminum foil, shiny side up.
2. Add hot water and 1 tablespoon of baking soda.
3. Place silver items in the solution, ensuring they touch the foil.
4. Wait 2-5 minutes — the tarnish transfers to the foil.
5. Rinse and dry with a soft cloth.

12. Clean Your Dishwasher

1. Sprinkle 1 cup of baking soda on the bottom of an empty dishwasher.
2. Add 1 cup of white vinegar to the bottom.
3. Run a hot cycle without any dishes.
4. This can help remove buildup and deodorize the machine.

Baking Soda Cleaning Recipes

Safety Notes

• Baking soda is non-toxic and food-safe.
• It’s a mild abrasive — safe for most surfaces but avoid on delicate materials.
• Don’t use on aluminum, marble, or gold-plated items.
• Never mix baking soda with bleach — it can produce harmful chlorine gas.
• ⚠️ Never mix cleaning products unless the manufacturer specifically states they are safe to combine. Mixing household cleaners (bleach + ammonia, bleach + vinegar, different drain openers) can produce toxic gases or dangerous reactions. Use one product at a time and rinse surfaces thoroughly before switching.

The Bottom Line

Baking soda is a versatile and affordable addition to your cleaning routine. It handles tasks like oven scrubbing, carpet deodorizing, and stainless steel polishing — often at a lower cost than buying separate specialized products.

Start with the oven clean and the drain maintenance — two of the more practical everyday uses that many people find helpful.
