If you’ve opened your washing machine and noticed a musty odour or black slimy patches around the rubber seal, you’re not alone. Many UK households face this hidden problem. The big question is: is black mould in washing machine dangerous?
The answer is yes – it can be. Not only does it impact your health, but it also affects the cleanliness of your clothes and the lifespan of your machine. In this article, we’ll explore the risks of black mould, how to spot it, safe cleaning methods, and practical prevention tips for UK homeowners.
What is Black Mould in Washing Machines?
The black mould you see inside washing machines is usually Stachybotrys chartarum or other common mould species. It thrives in moist, warm, and poorly ventilated spaces – exactly the kind of environment inside a washer, especially around:
- The rubber door seal (gasket)
- Detergent drawers
- Water pipes and filters
The build-up of detergent, fabric softener, and lint provides the perfect food source for mould growth.

Is Black Mould in Washing Machines Dangerous?
Yes. While it may not always be life-threatening, black mould can pose serious risks:
- Health concerns: Exposure can cause respiratory issues, asthma flare-ups, skin irritation, and allergies. The NHS notes that prolonged exposure to mould can worsen health in vulnerable groups, such as children, the elderly, and those with weakened immune systems.
- Dirty clothes: Instead of coming out fresh, your clothes may smell damp and harbour bacteria.
- Machine damage: Over time, mould can degrade the rubber seal, cause blockages, and reduce machine efficiency.
Signs of Black Mould in Washing Machines
You may be dealing with mould if you notice:
- Black spots or patches on the seal, drawer, or drum.
- Musty or foul odour coming from clothes or the machine.

How to Clean Black Mould in Washing Machines
Here’s a step-by-step guide to getting rid of mould:
- Wear gloves and a mask – Protect yourself from mould spores.
- Clean the rubber seal – Use a mixture of white vinegar and baking soda, scrubbing into the folds with an old toothbrush.
- Disinfect the detergent drawer – Remove it, soak it in hot water and vinegar, then scrub clean.
- Run a hot wash cycle – Set your machine to 90°C with no clothes inside. Add 500ml of white vinegar or a commercial washing machine cleaner.
- Dry the machine – Leave the door open after each wash to reduce moisture.
UK households can also use commercial cleaners from trusted retailers like Currys or John Lewis.
Prevention Tips
Prevention is key if you want to avoid black mould returning:
- Leave the door open after each cycle to allow airflow.
- Use less detergent and fabric softener, as excess residue feeds mould.
- Run a monthly maintenance wash at high temperatures with vinegar or a cleaner.
- Wipe seals dry regularly after use.
- Check and clean filters every few months.
