Baking soda—also known as sodium bicarbonate—has long been celebrated as one of the most versatile staples in the household. While most people know it as a key ingredient in baking or a reliable tool for cleaning surfaces, few fully understand just how powerful it can be when used correctly in laundry care and appliance maintenance. Many of us have tossed a handful into the wash without much thought, often using it incorrectly and missing out on its full potential.

In this expanded guide, we take a deeper look into the science behind baking soda’s odor-neutralizing properties, the mistakes that reduce its effectiveness, and the best methods for incorporating it into your laundry routine. Whether you're dealing with stubborn gym odors, lingering pet smells, or simply want to keep your washing machine in peak condition, learning to use baking soda the right way can truly transform your cleaning habits.

1. The Science Behind Baking Soda’s Odor-Fighting Power

Baking soda works because of its unique chemical nature: it's a mild alkaline compound that reacts with acidic and basic odor molecules, neutralizing them instead of simply masking the smell. This makes it especially effective on sweat, body oils, and pet odors—all of which often contain acidic components.

When added to laundry water, baking soda helps balance the pH level, creating a more favorable environment for detergents to work efficiently. With optimized pH, detergents break down dirt and oils more effectively. For most laundry loads, experts recommend using ½ cup per wash, though smellier loads may require slightly more.

2. Common Mistakes People Make with Baking Soda

A surprisingly common error is underusing baking soda. Throwing in just a spoonful won’t make a difference—proper odor neutralization requires using enough product.

Another mistake is placing baking soda in the detergent drawer, where moisture can cause clumping and reduce effectiveness. It should always go directly into the drum.

And while baking soda is powerful, it is not a detergent substitute. It works best as a booster alongside your regular laundry soap, not in place of it.

3. How to Properly Use Baking Soda in Laundry

For best results, sprinkle ½ cup of baking soda directly into the washing machine drum before adding clothes. This ensures even distribution and prevents clumping.

For heavily soiled or extra-smelly laundry—like sweaty sportswear or towels—use up to 1 cup.
You can also dissolve baking soda in warm water before adding it to help it disperse even more evenly throughout the wash.

4. The Right Way to Add Baking Soda to the Washing Machine

Always place baking soda inside the drum, not in the detergent tray.

• Top-loaders: Sprinkle the powder on top of clothes.

• Front-loaders: Dissolve it in a cup of warm water and pour it into the drum.

This ensures that the baking soda comes into direct contact with water and detergent, maximizing its cleaning power.

5. Baking Soda Hacks for Freshening Gym Clothes

Because gym clothes often trap sweat and bacteria deep within synthetic fibers, baking soda can be a game-changer.

Try this two-step method:

1. Pre-soak clothes in ½ cup baking soda mixed with 1 gallon of water for 30 minutes.

2. Add another ½ cup to the wash cycle along with your detergent.

This routine helps eliminate odors at the fiber level, leaving gym clothes noticeably fresher.

6. Eliminating Pet Odors with Baking Soda

Pet bedding, blankets, and soft toys can hold onto odors—but baking soda can pull those smells out naturally.

• Sprinkle baking soda generously onto the fabric.

• Let it sit for 15–30 minutes.

• Vacuum thoroughly.

For washable items, place ½ cup of baking soda into the wash cycle. Persistent odors may require a pre-soak.

7. How Baking Soda Helps Maintain Your Washing Machine

Beyond laundry, baking soda helps keep your washing machine clean by removing detergent residue and mineral buildup that can affect performance.

Once a month, run an empty hot-water cycle with 1 cup of baking soda.
This helps reduce odors, prevent buildup, and extend the lifespan of your machine.

8. Using Baking Soda and Vinegar the Right Way

Although baking soda and vinegar are a viral cleaning duo, they work best when used separately, not mixed in the same cycle.

• Use baking soda in the wash cycle to neutralize odors.

• Use vinegar in the rinse cycle to soften fabrics and remove detergent residue.

Mixing them directly causes them to neutralize each other—wasting their cleaning power.

9. Eco-Friendly Benefits of Baking Soda

Baking soda is biodegradable, non-toxic, and safe for children, pets, and the environment. It offers a natural alternative to chemical-heavy laundry boosters and fabric refreshers.

It’s also budget-friendly, giving families an affordable cleaning solution that lasts for many loads.

10. Viral Baking Soda Hacks: What Actually Works?

While baking soda is fantastic for deodorizing, it isn’t a miracle product.

• It can brighten whites, but won’t replace bleach.

• It can soften fabrics, but won’t outperform dedicated softeners.

• It can remove light stains, but won’t lift all deep-set stains on its own.

Use it as an enhancer—not a total replacement—for specialized cleaning products.

11. Expert Tips for Maximizing Its Effectiveness

• Use the proper amount (½–1 cup per load).

• Pre-soak extra-smelly items.

• Store baking soda in a cool, dry place to prevent clumping.

• Pair it with detergent, not in place of it.

• Use vinegar only in the rinse cycle, never mixed with baking soda in the wash.
