How to Easily Remove Mold from Washing Machine Rubber Seals Without Bleach or Vinegar

The rubber seal on a washing machine door is one of the most common areas where bacteria and mold can accumulate if not cleaned regularly. Once mold begins to grow in this damp, hidden spot, it can cause unpleasant odors and even transfer dirt or mildew onto freshly washed clothes. Fortunately, you can easily remove mold from this area using a simple, affordable household product—without relying on bleach or vinegar.

While mold is a common hygiene issue that can affect various parts of a washing machine, many households tend to overlook the rubber door seal. This area often traps moisture, dust, lint, and leftover detergent—creating the perfect environment for mold and mildew to thrive. Over time, this buildup not only compromises the washer’s ability to seal properly but can also shorten its lifespan and leave your laundry smelling musty.

Cleaning expert Debbie Young from Scrub Hub, speaking to Express, explained that you don’t need harsh chemicals or expensive cleaners to tackle the issue. Instead, she recommends using regular dishwashing liquid, a product found in nearly every kitchen. Dish soap is excellent at cutting through grease and grime, and it also works wonders for removing buildup inside washing machines.

“You don’t need to call a professional or spend money on costly detergents,” Debbie says. “A traditional dish soap is a simple, inexpensive, and effective choice.”
She adds, “When the washing cycle combines hot water and dish soap, it helps break down residue and remove mold just as effectively as it does on dishes.”

Step-by-step method to clean mold from your washing machine

1. Empty the drum. Make sure there are no clothes inside the washer.

2. Add dish soap. Pour a small amount of dishwashing liquid directly into the drum.

3. Run a hot cycle. Add a little water into the detergent drawer, then select a full wash cycle at 90°C (194°F).

4. Wipe the seal. Once the cycle is complete, use a clean cloth or sponge to gently wipe around the rubber seal. The mold and grime should come off easily—no scrubbing required.

For stubborn spots, you can dip a soft toothbrush in a mixture of warm water and dish soap to reach deep folds in the gasket. This ensures every corner is thoroughly cleaned and prevents future buildup.

Preventing mold from returning

To keep your machine mold-free, remember to leave the door slightly open after every wash. This allows air to circulate and helps the rubber gasket dry completely, preventing moisture from lingering. You can also remove the detergent drawer occasionally and rinse it under hot water to clear out any soap residue.

Another helpful habit is to run a “maintenance wash” once a month using dish soap or a specialized washing machine cleaner. This keeps your washer smelling fresh and operating efficiently.

As Debbie emphasizes, tackling mold doesn’t have to be difficult or time-consuming.

“You simply let the machine and the dish soap do the work,” she says. “Once the hot cycle finishes, your washing machine will be clean, fresh, and ready to use—no unpleasant odors, no mold, and no fuss.”
