Problem:[header] How to clean the inside of a washing machine [title] Fill the machine with hot water. [step] Newer models of front-loading machines often have self cleaning cycles, so if this is the case with yours, fill it with hot water on this setting. If you don't have a self-cleaning cycle, just fill it with hot water. <sep> (A) [title] Add a quart of bleach for stain removal. [step] If the inside of your washer is stained, bleach will do the trick. (B) [title] Add fabric softener into the water. [step] It can be as convenient or as time-consuming as you like, but fabric softener works by helping kill germs, which is why use it rather than the regular soap. (C) [title] Soak a clean cloth in the hot water. [step] The cloth should be damp, but not soaking-wet, but not too wet that it becomes cold. (D) You should only use hot water to turn the machine on. [substeps] You can turn the machine off manually.
