How to Remove Mould from a Washing Machine and Prevent It Returning

A washing machine is one of the most essential appliances in the home, yet it can also become one of the places most likely to develop mould and unpleasant smells. This is because moisture, leftover detergent and limited airflow combine to create the perfect conditions for fungi to grow. The good news is that there is a straightforward, effective method to clean the machine thoroughly and help stop the issue from returning.

Why does mould form inside the washing machine?

Mould tends to develop in a washing machine mainly because dampness lingers after each wash cycle. Even when the programme has finished, small amounts of water can remain trapped in places such as the door seal, the detergent drawer and the drum.

On top of that, using too much detergent and fabric softener makes the problem worse, as these products can leave behind residues that effectively feed fungal growth. If the machine is kept closed for long periods, the inside becomes even more hospitable, allowing mould to spread more easily.

How do you deep-clean a washing machine?

A proper deep clean of a washing machine is best done in stages: start with the inside of the drum, then work through the parts that commonly hold moisture and build up residue. The aim is to remove existing mould and sanitise the appliance thoroughly.

Using cleaning agents such as hot water and disinfectant products helps break down built-up deposits and kill fungi, resulting in a more effective clean.

• Empty the machine completely before starting the clean
• Run a hot wash cycle with a disinfectant product
• Clean the door seal and the drum by hand
• Sanitise the detergent and fabric softener dispenser
• Repeat with a rinse cycle to flush out remaining residue

How do you clean hidden areas where mould builds up?

The most problematic parts of a washing machine are often the ones that are easiest to overlook-such as the door seal, the filter and the detergent drawer. These areas stay damp and can keep mould active even if you only do a surface-level clean.

For that reason, careful, detailed manual cleaning is essential to ensure no pockets of fungus are left inside the appliance.

• Door seal (rubber gasket)
• Detergent and fabric softener drawer
• Lint filter
• Inside of the drum
• Outer edge of the seal

How can you prevent mould from coming back in the washing machine?

Once the machine is clean, the most important step is adopting habits that reduce the chances of mould returning. Small changes to your routine are often enough to keep the appliance fresher for longer and prevent unpleasant odours.

Ventilation and moisture control are the key factors in stopping fungi from growing again.

• Leave the washing machine door open after use
• Use the correct amount of detergent
• Avoid using too much fabric softener
• Dry the door seal regularly
• Do monthly maintenance cleans

Eliminating mould effectively
