Before cleaning the washer drum, clean the gasket by spraying it with white vinegar and wiping with a damp microfiber cloth. The rubber gasket at the front of the washer, especially in a high-efficiency (HE) washer, accumulates water, hair, scum and mildew.
Set the washer to the highest level and the hottest water temperature.
Add two cups of white cleaning vinegar to detergent dispenser.
Run it through a complete cycle.
Run another cycle on the highest level and at the hottest water temperature, this time adding one-half cup of baking soda to the drum.
When cycle is done, wipe inside drum of washer with a damp microfiber cloth.
While you’re at it, wipe down the front of the machine, too.
