There are several ways to use vinegar and baking soda to clean your washing machine. One way is to mix 2 cups of vinegar, and 1/4 cup of baking soda and water each, then pour the mixture into the detergent cache of your washing machine. Simply run a cycle at the highest temperature. You can also use the same mixture to clean the washing machine's door, drum, and detergent drawer.

Another way to use baking soda and vinegar to clean your clothes cleaner is to spray vinegar around the gasket, then use a rag to remove any mold, soap scum, and detergent build-up before running the machine. Be sure to also clean the drum with the vinegar and baking soda solution we just described. You can also use vinegar in a spray to clean the front, or top of the washing machine before wiping that down. 

While some cleaners say once every six months is enough to keep your washing machine spick and span, others advise you'd be better off doing this task at least once a month, and even more often if you catch a whiff of mildew.
