How To Clean Front-Load Washer Mold

Front-loading washing machine with mold growing on the door gasket

Mr. Appliance® explains how to clean mold from a front-load washer to maintain freshness and efficiency.

  • Mold starts in the gasket. The rubber door seal traps moisture and detergent residue.
  • Use bleach, vinegar, or baking soda to safely remove mold buildup.
  • Clean the dispensers and door regularly to stop residue and odor formation.
  • Run a sanitize cycle monthly to disinfect the drum and kill hidden mold.
  • Leave the washer door slightly open after each cycle to let it dry.
  • Use high-efficiency (HE) detergent to reduce suds and residue buildup.
  • Skip liquid fabric softener to prevent mold-attracting film and residue.

If your front-load washer has visible grime around the door seal or your laundry smells musty after washing, the problem might be mold. 

Front-load washer mold can be cleaned using a variety of methods, including bleach, mildew remover, vinegar, or baking soda. However, the best method is prevention, which means allowing your washer to dry out completely between washes and sanitizing it regularly.

In this article, we’ll cover how to remove washer mold, prevent its return, and maintain fresher, cleaner laundry.

Tools for Cleaning a Front-Load Washer

Tools for cleaning mold in a front-load washer.

Before tackling front-load washer mold, you’ll need to round up some cleaning tools and materials. Most are items you may already have on hand:

  • Cleaning rag or microfiber cloth
  • Mildew cleaner or all-purpose cleaner
  • Dish soap
  • Bristled cleaning brush
  • Vinegar
  • Baking soda
  • Bleach
  • Gloves
  • Paper towels
  • Toothbrush

Always wear gloves when using bleach or mildew cleaner, and ensure good ventilation during cleaning.

1. Clean the Gasket

The gasket—the rubber ring inside the washer door—is where most mold develops. With use, the tight seal traps detergent residue and moisture, creating an ideal environment for mold growth.

To clean it, start by putting on gloves and trying one of these methods:

  • Spray a rag with mildew cleaner or bleach solution and wipe the gasket thoroughly, including behind the rubber folds.
  • Use a bristled brush with vinegar, baking soda paste, or mild dish soap to scrub the gasket and surrounding areas.
  • For heavy buildup, line the gasket with paper towels sprayed with bleach. Let them sit for about 10 minutes, then remove and run an empty rinse cycle.

Be sure to clean underneath the gasket seal, too. Mold and residue are often found in this hidden area.

2. Clean the Dispensers

Detergent and fabric softener dispensers often develop sticky buildup that encourages mold growth. Your first clue may be a smelly washing machine or musty-smelling laundry.

Remove the dispensers and wash them with warm, soapy water. Use a toothbrush to reach into tight areas. If your dispensers can’t be removed, wipe them out as thoroughly as possible with a rag dipped in vinegar or mildew cleaner. Regular cleaning every month or two will prevent residue and odors from forming.

3. Clean the Washer Door

Mold can accumulate around the edges of the washer door and along the rubber seal. Spray the door and its edges with vinegar, bleach solution, or mildew cleaner. Wipe the gunk off with a rag or paper towel, and use a toothbrush to scrub the grooves and corners. Rinse the door with water and leave it open to air dry.

4. Run a Sanitize Cycle

If your front-loading washing machine has a sanitize cycle, use it to remove any remaining mold and bacteria. Run the cycle empty and add one of the following:

  • One cup of bleach
  • One cup of baking soda
  • One cup of vinegar
  • One washer-cleaning tablet

(Note: Add only ONE of the above…You never want to combine bleach, vinegar, and baking soda!)

This step will disinfect the drum and hoses. Repeat monthly for ongoing maintenance and prevention.

How To Prevent Mold in a Washing Machine

Mr. Appliance explains how to prevent front-load washer mold.

Front-load washers are more prone to mold than top-load machines, so prevention is key. A few simple habits can make all the difference:

  • Leave the door slightly open after each cycle to help the drum dry out.
  • Wipe down the gasket after each use to remove trapped moisture.
  • Use HE detergent designed for high-efficiency washers to reduce suds and residue.
  • Skip liquid fabric softeners and switch to dryer sheets or wool dryer balls instead.
  • Run a hot bleach cycle once a month to keep the drum clean and odor-free.
