The rubber seal needs to be regularly cleaned using a damp clean cloth to prevent a build-up of mold and bad smells.
Bosch washing machine rubber seal mould. Has worked without any problem at all throughout. It creates a conducive environment for mildew and mold to grow. We did get some mould on the front door seal but a call to Bosch advised to wipe the rubber seal after each wash and leave open to air.
Use the dampened rag to scrub the black mold from the rubber seal. Put on rubber gloves to protect your hands and a dust mask to avoid inhaling mold spores. I am worried that all those harsh chemicals could destroy the rubber seal itself and make holes in it and then the problem would become even more difficult and potentially expensive to solve.
I changed to a front loader earlier last year and wondered why my machine stank. It will take several Q-tips to fully clean the inside of the gasket. Not only can bad smells come from the washing machine drum they can also accumulate in the rubber door seal.
If you reach under the washing machine door seal and run your hand across the rubber it is possible to feel the black sludge that has developed there. If black moldy spots remain. Wipe the cleaner away with a clean cloth or paper towel.
This features airtight watertight doors that often come with a rubber seal. Spray the seals interior with hot soapy water or a mildew cleaner. This mold and the bad smells it produces are then transferred to the clothes.
My repair man told me that the main problem with all washing machines is people using the wrong detergent and too much. This seal can easily trap moisture in the washing machine. Gently stir this chlorine solution.
