Soap scum and mineral deposits can build up in the hoses of your washer restricting water flow and performance. Four times per year, remove soap scum and clean the hoses by using hot water and a cup of white distilled vinegar in the wash cycle. This routine cleaning should be done with no clothes in the washer.
If you have automatic detergent or fabric softener dispensers, use heated white distilled vinegar to clean any build-up that may limit performance. Just pour in the hot vinegar and let it work. Run the washer thorough a hot water cycle with no clothes.
