The rubber gasket around a washing machine door is one of the areas most prone to bacteria and mold buildup if it is not cleaned regularly. Once mold appears in this hidden but crucial spot, many people assume they need vinegar or bleach to remove it. However, there is a much simpler and more affordable solution that does not involve harsh chemicals.

Although mold is a common hygiene issue that can affect various parts of a washing machine, many households tend to overlook the rubber seal around the door. This gasket is constantly exposed to moisture, detergent residue, and trapped dirt, creating an ideal environment for mold and mildew to thrive. Over time, this buildup can become difficult to remove if left untreated.

Mold on the rubber seal not only compromises the machine’s ability to seal properly but can also shorten its lifespan. Even worse, it may cause freshly washed clothes to come out smelling unpleasant, looking dirty, or contaminated with unwanted residue. According to cleaning expert Debbie Young from Scrub Hub, who shared her advice with Express, there is no need to rely on strong chemical cleaners. Instead, a simple, effective, and budget-friendly method using a common kitchen product can do the job just as well.

Debbie recommends using dishwashing liquid—an item found in nearly every household—rather than spending money on specialized or expensive cleaning products. Dish soap is well known for its ability to cut through grease and stubborn grime on dishes, but it is also surprisingly effective for cleaning washing machines and eliminating mold buildup.

“You don’t need to call a professional or use costly cleaning solutions,” Debbie explains. “Traditional dishwashing liquid is a simple, inexpensive, and highly effective option.” She adds, “When a dishwasher runs, hot water combined with dish soap helps break down residue and dirt. The same principle applies when cleaning the inside of a washing machine.”

To remove mold from your washing machine, follow a few easy steps. First, make sure the drum is completely empty. Then, add a small amount of dishwashing liquid directly into the drum. Pour some water into the detergent compartment and select a wash cycle with a high temperature—ideally around 90°C. Once the cycle is finished, use a clean cloth or sponge to gently wipe the rubber gasket. The mold and grime should come off easily, without the need for harsh scrubbing or excessive effort.

To prevent mold from returning, it is important to allow the washing machine to dry properly after each use. Leaving the door slightly open helps air circulate and ensures the rubber seal dries completely, reducing moisture buildup and discouraging mold growth.

Debbie emphasizes that dealing with mold can be incredibly simple. “You just let the washing machine and dish soap do the hard work,” she says, “then enjoy a clean, fresh-smelling appliance.” After completing the hot wash cycle, the machine is ready to be used as normal—clean, hygienic, and free from unpleasant odors.
