Baking Soda Is the Secret to Odor-Free Clothes—But Most People Use It Wrong

Baking soda has long been considered a simple, low-cost solution for fresher laundry and cleaner washing machines. However, experts say that many people are not using it correctly—leading to disappointing results.

When used properly, this common household ingredient can significantly improve cleaning performance, remove stubborn odors, and even extend the life of your washing machine.

Why Baking Soda Works So Well

Baking soda (sodium bicarbonate) is a mild alkaline substance that helps neutralize acidic odor molecules rather than simply masking them.

This makes it especially effective for removing smells caused by sweat, mildew, or bacteria—common issues in clothing and washing machines.

In addition, it helps balance the pH level of water, allowing detergent to work more efficiently and clean more thoroughly.

The Most Common Mistakes People Make

Despite its effectiveness, many people reduce its power by using it incorrectly. Experts highlight several common mistakes:

• Using too little: Small amounts may not effectively eliminate odors
• Pouring it into the detergent drawer: This can cause clumping and prevent proper dissolving
• Using it without detergent: Baking soda is not a substitute for laundry detergent
• Mixing it with vinegar at the same time: The two cancel each other out chemically

These mistakes can make people think baking soda “doesn’t work,” when in reality, it’s just being used the wrong way.

The Right Way to Use Baking Soda in Laundry

To get the best results, experts recommend:

• Add about ½ cup of baking soda directly into the washing machine drum
• Use it along with regular detergent, not instead of it
• For strong odors (like gym clothes or towels), increase to up to 1 cup
• Optionally dissolve it in warm water for better distribution

This method helps eliminate odors at the source and improves overall washing performance.

How to Remove Tough Odors and Stains

For stubborn smells or stains:

• Mix baking soda with water to create a paste
• Apply directly to the affected area
• Let it sit for 15–30 minutes before washing

This technique can help break down grease, sweat stains, and deeply embedded odors.

Cleaning Your Washing Machine with Baking Soda

Baking soda isn’t just for clothes—it can also help clean your washing machine.

Running a hot cycle with baking soda can remove odor-causing residue and bacteria buildup inside the machine, keeping it fresh and efficient.

Regular maintenance helps prevent unpleasant smells from transferring back onto your clothes.

What to Avoid

To prevent damage or poor results:

• Avoid using baking soda on delicate fabrics like silk or wool
• Don’t overuse it, as excess residue may build up
• Always follow your washing machine’s guidelines

The Bottom Line

Baking soda is a powerful, natural laundry booster—but only when used correctly.

By adding the right amount in the right place and avoiding common mistakes, you can achieve fresher clothes, better cleaning results, and a cleaner washing machine—all without harsh chemicals.
