How to Clean Washing Machine
The machine that cleans your clothes can become surprisingly dirty itself—detergent residue, fabric softener buildup, and trapped moisture create the perfect environment for mold, mildew, and odor-causing bacteria. This maintenance task involves running a hot cleaning cycle with vinegar or a washing machine cleaner, wiping the door gasket folds (especially on front-loaders where water and debris collect), and cleaning detergent dispensers. Monthly cleaning keeps your washer fresh and ensures your clean laundry actually smells clean.

Why It Matters
Washing machines develop mold, mildew, and bacteria in the drum, gaskets, and dispensers. Front-loaders are especially prone. This transfers to your clothes and causes musty odors. Clean monthly, or more often if you notice odors. Always leave the door and dispenser drawer open after washing to allow drying. Front-loaders need more attention than top-loaders due to their sealed design.
Safety First
- Use cleaning products as directed - do not mix bleach with vinegar
- Leave the door ajar after every wash to prevent mold
