According to Reviewed.com, vinegar and baking soda are the best products to clean your washer. Adding vinegar and baking soda to an empty wash cleans out any mold or mildew buildup. About.com suggests lemon as a satisfactory alternative to vinegar.
Cleaning the lid and door of the washing machine can eliminate mildew and old detergent buildup. Choose the detergent based on the type of washer owned. Front-loading washers are typically more efficient and need a detergent made for high-efficiency washers. Excessive suds can be hard for front-loading washers to expel, leaving behind residue for bacteria, mildew and mold to grow in.
