Mildew growth on rubber seals located inside the doors of front loading washing machines is a common problem. The rubber seals are meant to prevent water from leaking out of the washing machine during a cycle. However, water often collects in the front cavity of the door on the machine. If the water isn't removed quickly, it allows mildew to grow. The odour and appearance of mildew can be displeasing and should be cleaned to prevent further development.
Wipe down the rubber seal using a dampened cloth to remove any loose dirt.
Add 1 part bleach to 2 parts water in a spray bottle and mix.
Spray the rubber seal with the diluted bleach solution and allow it to penetrate the mildew for three to five minutes.
Wipe away the mildew and bleach solution using a clean cloth. Use a cotton swab to clean any small crevices between the seals.
Repeat steps 3 and 4 until the mildew is completely removed.
Wipe down the seals using a cloth moistened with a few drops of liquid detergent.
