The gasket on a front-load washer is a rubber seal located around the door that helps it remain shut when your washing machine is running through a cycle. The gasket has a very important job and, unfortunately, it is exposed to some very nasty substances. Problems can develop with your front-load washer if your gasket is dirty, including a foul-smelling odor or even an issue with mold formation. Cleaning your gasket regularly can help avoid such occurrences.
Sprinkle baking soda along the gasket of your front-load washer and allow it to sit for several minutes to absorb any odor.
Dampen a nonabrasive sponge with water and use it to scrub the rubber material with the baking soda.
Rinse the gasket with clean water. If you see any mold formations, continue cleaning.
Dilute 2 tbsp. of bleach in 1 gallon of water.
Soak a clean cloth in the bleach solution and wipe down the gasket thoroughly to remove the mold. Use your sponge if scrubbing is necessary for the removal.
Rinse the gasket with plain water. If odor is still an issue, continue.
Add 1 cup of bleach to your front-load washer's dispenser and run it through a normal wash cycle. After the cycle's end, open the washer door and allow the machine to air for a few hours to thoroughly remove the odor.
