How to Clean Rubber Seals

Updated February 21, 2017

Rubber seals are used in many household items like dishwashers, showers and even in cars. A rubber seal is used to create a barrier water cannot pass through. Since rubber seals are always used around water, they tend to get grime and mould growing on them. Cleaning these rubber seals can be done with common household cleaners. Cleaning rubber seals will keep the area surrounding the seal sanitary and prevent the spread of mould through your home.

Turn on your sink and run some warm water onto a sponge. Put a couple drops of liquid soap onto the sponge. You can also use a different cleaner, but make sure it does not contain bleach.

Open the appliance or the shower door that contains the rubber seal. Run your sponge over the seal until you start to see the gunk come off.

Use a wet toothbrush and your cleaning agent to get into the hard to reach spots on the seal.

Run warm water onto your sponge until all of the cleaning agent is gone. Wash the seal off with warm water to cleanse it. Use a paper towel or a rag to dry the surface of the seal.


Never use bleach on a rubber seal, as it will cause it to break down over time.
