How to Prevent Mold in Your Washing Machine

If your washing machine has started to smell less like fresh laundry and more like a damp basement, mold could be the culprit. Washing machines—especially front-load models—create the perfect environment for mold growth: warm, damp, and dark. The good news? With a few simple habits, you can prevent mold from taking over your washer.

1. Leave the Door Open After Washes

Mold thrives in trapped moisture. After every cycle, leave the door (or lid) cracked open so air can circulate. This helps the drum dry out faster and reduces the chance of mildew forming.

2. Wipe Down the Rubber Gasket

Front-load washers have a rubber gasket around the door that’s notorious for trapping water, lint, and even small clothing items. That build-up is a breeding ground for mold.

  • After each wash, wipe the gasket with a dry cloth.
  • Once a week, check for hidden debris and clean with a mild vinegar solution.

3. Use the Right Detergent

Too much detergent or the wrong kind can cause excess suds, which stick to the drum and feed mold.

  • Use HE (high-efficiency) detergent in the correct amount.
  • Skip fabric softener if possible—it can leave a residue that traps odors.

4. Run a Cleaning Cycle Monthly

Most modern washers have a “clean washer” cycle. Run it once a month with an empty drum. If your washer doesn’t have this feature:

  • Add 2 cups of white vinegar and run a hot cycle.
  • Then run a second hot cycle with ½ cup of baking soda.

5. Keep the Detergent Dispenser Clean

Detergent and fabric softener drawers can collect gunk over time. Remove and rinse them monthly to prevent buildup and smells.

6. Don’t Let Wet Clothes Sit Inside

Leaving damp laundry in the washer is a fast track to mold and sour odors. Transfer clothes to the dryer (or the line) as soon as the cycle finishes.

Bottom Line

A moldy washing machine can make your clothes smell worse than before you washed them. By keeping the drum dry, cleaning regularly, and using the right detergent, you can stop mold in its tracks—and keep your washer fresh and efficient for years.
