How do I clean the interior of the WTW6200SW washing machine?

Clean the washer interior by mixing 1 cup (250 mL) of chlorine bleach and 2 cups (500 mL) of detergent and pouring the mixture into the washer, then running it through a complete cycle using hot water. Repeat the process if necessary, and remove any hard water deposits using only cleaners labeled as washer safe. Use a soft, damp cloth or sponge to wipe up any spills such as detergent or bleach from the outside of the washer. (Page 17)
