To clean a Whirlpool washing machine, follow these key steps:

1. Prepare supplies like a soft cloth, toothbrush, liquid chlorine bleach or white vinegar, baking soda, and if available, an Affresh cleaning tablet.
2. Empty the washer completely before cleaning.
3. Clean the exterior with a damp cloth.
4. Deep clean the detergent drawer by removing and washing it.
5. Sanitize the rubber door seal by wiping it with white vinegar and using a soft brush for grime.
6. Clean the filter and check the drain pump every 2-3 months.
7. For the drum, use an Affresh tablet or a mixture of 2 cups white vinegar and 1/4 cup baking soda; run the hottest wash cycle.
8. After cleaning the drum, wipe it dry and leave the washer door open to air out and prevent odors.
9. Use the "Sanitize with Oxi" feature if your machine has it, for a deeper clean.

Regular cleaning every month helps keep the washer running well and clothes smelling fresh. These steps cover all critical areas including the drum, door seal, dispenser, filter, and exterior.
