The best way to clean your Whirlpool top loader washing machine is to use the Clean Washer cycle. Follow the cycle instructions on the bottle of washer cleaner you have with you. The higher water volumes in this cycle help maintain washer freshness while removing debris and grime from inside the machine. If you have a liquid chlorine bleach or an affresh​ product, run it through your Whirlpool top loader washing machine at least once per month to maintain freshness and prevent discoloring. If you use an effervescent cleaner or bleach, try using it once per month instead of every 30 cycles as recommended in the bottle of washer cleaner you have with you.
