Remove mould from washing machine

Why mould develops in washing machines

Mould thrives in warm and damp environments, exactly the conditions inside a washing machine after each cycle. When the door is closed after use, trapped moisture combined with detergent and dirt residues creates the perfect breeding ground for mould spores. Insufficient drying between cycles also encourages mould growth.

The most common areas where mould develops include:

The drum: Moisture accumulates in the drum and rubber seal, allowing mould to grow in small crevices.
The detergent drawer: Detergent and fabric softener residues that are not rinsed away properly provide an ideal food source for mould.
The door seal: The rubber seal around the door traps moisture, becoming a frequent mould hotspot if the door is not left open after washing.

To make sure if you have mould or not, use a mould test to check.

Fill the washing machine with hot water and add 2-3 deciliters of white vinegar. Run the machine on the highest temperature without laundry to disinfect and remove mould

How to remove mould from the washing machine

Removing mould from your washing machine is straightforward with the right cleaning routine and products. Follow these effective methods:

Use a washing machine mould cleaner: Choose a cleaner specifically designed for mould removal in washing machines. These products effectively break down mould spores and clean the drum, rubber seals and detergent drawer.
Run an empty hot wash with vinegar: Add 200–300 ml of white vinegar and run the hottest cycle without laundry. This helps disinfect the machine and remove odours.
Clean the detergent drawer: Remove the drawer, wash it with hot water and vinegar, and wipe it dry before reinserting. This prevents detergent build-up and bacteria growth.
Use dishwasher tablets or baking soda: Place one or two dishwasher tablets or two tablespoons of baking soda inside the empty drum and run a high-temperature cycle. This helps dissolve mould and remove musty smells.
Dry the machine after every wash: Leave the door and detergent drawer open to allow air circulation and prevent moisture from building up.

Preventing mould in your washing machine

Preventing mould is easier and more effective than treating it later. Use these preventive measures to keep your washing machine clean and mould-free:

Leave the door open: Always leave the washing machine door slightly open after each wash so that the interior can dry properly.
Remove laundry immediately: Do not leave wet clothes in the drum after washing, as damp laundry increases moisture and mould risk.
Use the right amount of detergent: Overusing detergent creates soap residue that mould feeds on. Follow dosage guidelines from the detergent manufacturer.
Clean regularly: Deep clean your machine at least once a month using a washing machine cleaner or vinegar and baking soda.
Check the seal: Wipe the rubber door seal after each wash to remove moisture and lint that can lead to mould.

Tips for keeping your laundry room mould-free

A mould-free laundry area is just as important as a clean washing machine. Follow these additional tips:

Ensure proper ventilation: Keep windows open or use a fan to allow airflow and reduce humidity.
Dry clothes quickly: Use a well-maintained tumble dryer or hang clothes in a ventilated area to prevent dampness.
Check for leaks: Inspect pipes, taps and hoses regularly for leaks that can raise humidity and cause mould growth.
Use a dehumidifier: In small or windowless laundry rooms, a dehumidifier helps control moisture and prevent mould buildup.

By combining proper cleaning, ventilation and maintenance, you can remove mould from your washing machine and keep it from returning. A clean machine not only protects your health but also ensures fresher, cleaner laundry every time.
