10 Everyday Household Uses of Baking Soda

Baking soda isn’t just a baking essential—it’s a household superhero. Thanks to its alkaline pH, odor-neutralizing abilities, and mild abrasiveness, it can replace dozens of chemical-based products in your home. Here are 10 brilliant ways you can use baking soda to clean, deodorize, and freshen up your living space:

1. Natural Deodorizer for Every Corner

Baking soda doesn’t just mask odors; it neutralizes them by balancing acidic and basic compounds in the air.

How to Use

• In the fridge: Place an open box of baking soda on a shelf to keep food odors at bay.
• In closets and drawers: Put a small bowl or sachet of baking soda to maintain freshness.
• For shoes: Sprinkle some baking soda inside shoes, leave overnight, and shake it out the next day.

💡 Pro Tip: Replace your deodorizing baking soda every 30–45 days for maximum effectiveness.

2. Stubborn Stain Remover

From coffee spills to greasy stovetops, baking soda’s alkaline properties make it a powerful stain remover.

How to Use

• Mix 2 tablespoons of baking soda with just enough water to form a paste.
• Apply directly to stains (mugs, kitchen counters, or tiles).
• Let it sit for 10 minutes before gently scrubbing.

🔍 Science Insight: Baking soda breaks down acidic compounds in stains, making them easier to lift without harsh chemicals.

3. Carpet & Upholstery Freshener

Carpets, rugs, and sofas often trap odors that vacuuming alone can’t remove. Baking soda absorbs unpleasant smells naturally.

How to Use

• Sprinkle a thin, even layer of baking soda over carpets or upholstery.
• Let it sit for 20–30 minutes.
• Vacuum thoroughly to remove both the powder and absorbed odors.

💡 Pro Tip: Add 5 drops of lavender or lemon essential oil to your baking soda before sprinkling for a fresh, lasting scent.

4. Cleans Kitchen Appliances Naturally

Baking soda’s gentle abrasiveness makes it perfect for cleaning microwaves, ovens, stovetops, and refrigerators without scratching surfaces.

How to Use

• Mix 3 tablespoons of baking soda with warm water to make a mild scrub.
• Use a sponge to clean stubborn grease and food residue.
• Wipe down with a damp cloth to finish.

⚡ Quick Hack: For a deep-cleaned microwave, heat a bowl of water + 1 tablespoon baking soda for 3 minutes. Steam loosens grime, making it easier to wipe away.

5. Removes Odors from Trash Bins

Trash bins can develop foul smells over time, even if emptied regularly. Baking soda helps absorb and neutralize these odors.

How to Use

• Sprinkle baking soda at the bottom of the bin before inserting a trash bag.
• For reusable bins, scrub them with a mixture of baking soda + warm water once a week.

💡 Pro Tip: Add a few drops of tea tree oil for natural antibacterial protection.

6. Natural Drain Cleaner

Skip harsh chemicals and unclog drains the eco-friendly way with baking soda and vinegar.

How to Use

• Pour ½ cup of baking soda into the drain.
• Follow it with 1 cup of white vinegar.
• Cover the drain and let the mixture fizz for 10 minutes.
• Flush with boiling water to clear residue.

🔍 Science Insight: The carbon dioxide bubbles from the reaction help dislodge grime, grease, and minor clogs effectively.

7. Laundry Booster & Odor Neutralizer

Baking soda enhances your detergent’s power, brightens whites, and eliminates odors from clothing and towels.

How to Use

• Add ½ cup of baking soda directly to the wash cycle along with your regular detergent.
• For musty towels, soak them in a mixture of ½ cup baking soda + warm water for 30 minutes before washing.

💡 Pro Tip: Pair baking soda with white vinegar during the rinse cycle for extra freshness and softness.

8. Polishes Silverware & Jewelry

Forget expensive polishing creams! Baking soda restores the shine to silver without scratching it.

How to Use

• Make a paste using 3 parts baking soda + 1 part water.
• Rub gently onto tarnished silver using a soft cloth.
• Rinse thoroughly and dry with a microfiber cloth.

⚡ Quick Hack: For heavily tarnished items, line a bowl with aluminum foil, add 1 tablespoon of baking soda, and pour boiling water. Place the silver inside for 2–3 minutes, then rinse and polish.

9. Cleans Bathroom Surfaces Effectively

Baking soda works wonders on bathtubs, sinks, tiles, and grout without damaging finishes.

How to Use

• Sprinkle baking soda directly onto surfaces.
• Scrub with a damp sponge to lift soap scum and mineral deposits.
• For tough grout stains, make a paste with baking soda and hydrogen peroxide, then scrub with an old toothbrush.

💡 Pro Tip: Regularly using baking soda in the bathroom also prevents mold and mildew buildup.

10. Neutralizes Pet Odors

If you have pets, you know how challenging it is to keep your home smelling fresh. Baking soda safely eliminates odors without exposing pets to harsh chemicals.

How to Use

• Let it sit for 15–20 minutes, then vacuum thoroughly.

⚡ Safety Note: Baking soda is non-toxic for pets when used externally, but avoid letting them ingest large amounts.

Pro Tip for Household Cleaning

For a DIY all-purpose cleaner, mix:

• 2 tablespoons baking soda
• 2 cups warm water

5 Health Benefits of Baking Soda

Baking soda isn’t just a cleaning powerhouse—it also offers impressive health benefits when used correctly. Thanks to its alkaline nature, it helps neutralize acids, soothe irritation, and improve certain bodily functions. However, moderation is key, and you should always consult a healthcare professional before long-term use.

11. Relieves Heartburn and Indigestion

Heartburn occurs when stomach acid flows back into the esophagus, causing a burning sensation. Baking soda acts as a natural antacid by neutralizing stomach acid.

How to Use

• Mix ½ teaspoon of baking soda in a glass of water.
• Sip slowly to relieve heartburn and acid reflux.

Scientific Insight

According to the U.S. National Library of Medicine, sodium bicarbonate (1) effectively reduces acid reflux when used in small amounts. However, frequent use can lead to electrolyte imbalances, so it’s best for occasional relief only.

Caution: Avoid using this remedy if you have high blood pressure or are on a low-sodium diet, as baking soda contains sodium.

12. Soothes Sore Throats and Mouth Ulcers

Baking soda has antibacterial properties that make it an effective home remedy for soothing sore throats and treating mouth ulcers.

How to Use

• Mix ½ teaspoon baking soda + ½ teaspoon salt in a cup of warm water.
• Gargle for 30 seconds and repeat 2–3 times daily.

Scientific Insight

Research published in the Journal of Oral Microbiology shows that baking soda can help maintain oral pH balance and reduce bacterial growth, speeding up healing for ulcers and infections (2).

13. Enhances Exercise Performance

Athletes sometimes use baking soda to delay muscle fatigue during intense workouts. This is because baking soda helps neutralize lactic acid buildup in muscles.

How to Use

Studies suggest taking 0.3 grams per kilogram of body weight about an hour before exercise can reduce fatigue and improve endurance.

Scientific Insight

• A study published in the Journal of Applied Physiology confirms that sodium bicarbonate supplementation can improve athletic performance, especially in high-intensity activities (3).

Note: Only attempt this under professional supervision, as improper dosage can cause nausea or stomach upset.

14. Promotes Oral Health and Freshens Breath

Baking soda is a popular ingredient in toothpaste and mouth rinses due to its ability to remove plaque, whiten teeth, and neutralize odors.

How to Use

• Dip a damp toothbrush into baking soda and gently brush your teeth once a week.
• Alternatively, dissolve ½ teaspoon in a glass of water and use it as a natural mouthwash.

Scientific Insight

According to the Journal of the American Dental Association, toothpaste containing baking soda is more effective at removing plaque and whitening teeth compared to regular toothpaste (4).

15. Supports Kidney Health

Baking soda may help patients with chronic kidney disease (CKD) by neutralizing excess acid in the blood, which the kidneys usually filter out.

How to Use

A healthcare professional may prescribe baking soda supplements for CKD patients to slow disease progression.

Scientific Insight

A study published in the Journal of the American Society of Nephrology found that sodium bicarbonate supplementation helped reduce kidney damage in patients with metabolic acidosis (5).

Important: Do not self-prescribe baking soda for kidney issues—always consult a doctor first.
