Wash Your Washing Machine
Odd as it might sound, it’s recommend that you clean your washing machine occasionally to prevent the build up of mold, mildew, soap deposits, and odors. This is especially important for front-loading machines.
On front loaders, after each load of laundry, use a dry cotton cloth to wipe dry the inside of the door and its rubber gasket. (Keep cloth handy with magnetic clip stuck to side of washing machine.)
Also, keep the door—or lid on top-loaders—open to allow air to circulate. Some front-loaders have a latch, called a magnetic door plunge, that holds the door open an inch or so. If your machine has such a latch, use it to air out the tub. Regardless of what kind of washing machine you have, once every three months run it empty (no clothes) with hot water and one cup of bleach to sanitize and refreshen the inside of the machine.
