Mold can grow in a washing machine and cause odours that can cause clothing to smell bad. Gaskets, pipe and the wash bin itself are areas where mould can grow in a washing machine. Mold spores can also cause an allergic reaction in many people. Removing mould in a washing machine and preventing future mould growth will keep the washing machine smelling clean and reduce potential allergens in the air from the mould spores.

  1. 1

    Make sure the washing machine is empty and pour 3 cups of bleach into it.

  2. 2

    Fill the washing machine with hot water on the regular cycle, and then turn it off

  3. 3

    Use a toilet brush and sponge to scrub under the rim, around gaskets and other areas that may often be splashed but not saturated with the bleach water.

  4. 4

    Allow the hot bleach water to soak in the washing machine overnight.

  5. 5

    Restart the washing machine and allow it to run through the entire cycle.

Tips and warnings

  • Do a load of whites after bleaching the washing machine so that any residual bleach does not stain coloured clothes. To prevent future mould, routinely bleach the washing machine.
  • Use rubber gloves when cleaning the gaskets with the sponge to avoid absorbing bleach through the skin.
