Baking Soda in Laundry: The Right Way to Eliminate Odors, Freshen Clothes, and Clean Your Washing Machine

Baking soda has been a trusted household staple for generations. While many people know it as a baking ingredient, it’s also one of the most effective natural products for freshening laundry, neutralizing odors, and maintaining your washing machine.

Used correctly, baking soda can boost your detergent’s cleaning power, help remove stubborn smells, and even extend the life of your washer. Here’s everything you need to know about using baking soda the right way.

Why Baking Soda Works So Well

Baking soda (sodium bicarbonate) is a mild alkaline compound that helps balance the pH of wash water. This allows it to:

• Neutralize acidic odors
• Help loosen dirt and grime
• Improve detergent performance
• Reduce musty smells
• Leave clothes smelling fresher

Instead of masking unpleasant odors with fragrance, baking soda helps eliminate many odor-causing compounds.

Common Mistakes to Avoid

Although baking soda is easy to use, several common mistakes can reduce its effectiveness.

Using Too Little

For a standard load of laundry, use:

• ½ cup for regular loads
• Up to 1 cup for heavily soiled or very smelly laundry

Replacing Detergent Completely

Baking soda is a laundry booster—not a substitute for detergent. It works best alongside your regular laundry detergent.

Adding It to the Wrong Place

For most washing machines, adding baking soda directly into the drum provides the best distribution. If your machine manufacturer recommends a different method, follow the owner’s manual.
