Ignoring the gasket

A dirty gasket can become a major source of odor.

Using fragrance to cover the smell

Strongly scented products may mask an odor without removing its source.

Can Baking Soda Remove Mold?

This is where expectations should remain realistic.

Baking soda may help with odors and light residue, but it should not be considered a guaranteed treatment for established mold or extensive microbial growth.

If you see significant mold-like buildup, particularly inside areas that are difficult to access, follow the manufacturer’s cleaning instructions or seek appropriate professional advice.

Don’t aggressively scrub contaminated areas without considering exposure to spores and the possibility that the underlying moisture problem remains.

The goal isn’t simply to make the machine smell better.

The goal is to remove the conditions causing the odor.

The Bottom Line

A washing machine doesn’t clean itself simply because it washes clothes every day.

Detergent residue, fabric softener, body oils, dirt, moisture, and trapped debris can gradually accumulate inside the machine and contribute to musty odors.

A measured amount of baking soda—such as about ½ cup in an empty cleaning cycle, when compatible with your machine—may help neutralize odors and loosen some residue.

But the most effective approach is bigger than one ingredient.

Clean the gasket.

Wash the detergent drawer.

Check the filter.

Don’t overload the machine.

Use the recommended amount of detergent.

Remove wet laundry promptly.

And allow the washer to dry between cycles.

Most importantly, follow your washing machine manufacturer’s instructions because different machines use different materials, cleaning programs, and maintenance procedures.

A simple bowl of baking soda may help freshen your washer, but a consistently clean and dry machine is what makes the biggest difference over time.
