How to clean a smelly washing machine.

A washer that makes laundry smell musty is harboring mold and detergent buildup, usually in the door gasket and drawer on a front-loader. A monthly clean cycle plus drying the seal fixes it.

Clean a washing machine by running an empty hot cycle with two cups of white vinegar (or a washer-cleaning tablet), then wiping the drum, door gasket and detergent drawer. On a front-loader, the rubber gasket and the drawer are where mold hides, so clean them by hand. Leave the door open between washes so it can dry.

Run a clean cycle

Start by running the machine empty and hot to flush the drum.

  • Set the hottest, largest cycle with no clothes
  • Add two cups of white vinegar, or use the washer's clean cycle with a tablet
  • Optionally run a second short cycle with a half cup of baking soda

Clean the gasket and drawer (front-loaders)

On a front-loader, mold and slime collect in the folds of the door gasket and in the detergent drawer. This is the real source of the smell.

  • Pull back the rubber gasket and wipe out the trapped water, hair and gunk
  • Remove the detergent drawer and wash it in the sink
  • Wipe both with a vinegar solution and dry

Keep it from coming back

Mold needs moisture. Take it away.

  • Leave the door and drawer open between washes to air-dry
  • Use the right amount of detergent — excess feeds buildup
  • Run a clean cycle once a month
