How to remove black mold from a washing machine seal

Updated February 21, 2017

Mold can become a problem in almost any home, even on your washing machine! Besides a place to grow, mould requires only moisture and a food source such as dirt or other organic material in order to grow. All of these requirements can be found around the seals of washing machine doors. If mould exists around your washing machine door, it can potentially spread throughout other areas of the home, often via clothes that come in contact with the mould. The proper control measures will prevent the risk of harmful mould side effects.

Put on rubber gloves and a surgical mask to protect yourself from the mould. Always wear protective gear when working around mould.

Fill a bucket with hot water and 1 tsp of liquid all-purpose cleaner. Agitate the water for 10 seconds to thoroughly mix the ingredients.

Dip a sponge in the solution. Wring out the sponge so it's moist but not dripping.

Pull back the rubber seal with one hand and scrub the mould with a sponge with the other hand. Scrub all the way around the seal with this method to remove as much of the mould as possible. Rinse the seal with clean water.

Fill a spray bottle with 5 cups of water and 1/2 cup of bleach. Shake the bottle to mix the ingredients together.

Pull the washer seal back and spray the bleach solution on it and the surrounding area. Use just enough to lightly coat the area. Let the bleach air dry overnight. The bleach will kill any remaining mould spores. Dispose of the sponge and rubber gloves.


Keep a dehumidifier near the washing machine if the washer is kept in a moist area such as a damp basement. Get rid of black mould the same way you get way of any other colour of mould.
