How to Remove Mould from Your Washing Machine and Stop Bad Odours

A washing machine is one of the most essential household appliances, yet it can also become one of the easiest places for mould and unpleasant smells to develop. That’s because moisture, leftover detergent and poor airflow combine to create ideal conditions for fungal growth. The good news is that you can tackle it with a straightforward, effective routine that cleans the machine thoroughly and helps stop the problem returning.

Why does mould form inside the washing machine?

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

On top of that, using too much detergent and fabric conditioner makes things worse, as these products can leave residue behind that effectively feeds fungal growth. If the machine is kept shut for long periods, the warm, enclosed space becomes even more suitable for mould to spread.

How do you deep-clean a washing machine?

A proper deep clean needs to be done in stages-starting with the inside of the drum and then working through every part that traps moisture and build-up. The aim is to remove any existing mould and sanitise the appliance thoroughly.

Using cleaning agents such as hot water and a disinfectant product helps break down residue and kill fungi, resulting in a more effective clean.

  • Empty the machine completely before you start cleaning
  • Run a hot wash cycle with a disinfectant product
  • Wipe the door seal and the drum by hand
  • Clean the detergent and fabric conditioner dispenser
  • Run an extra rinse cycle to flush away any remaining residue

How do you clean hidden areas where mould builds up?

The most problematic parts of a washing machine are often the ones people overlook-such as the door seal, the filter and the detergent compartment. These areas stay damp and can keep mould active even after a quick surface clean.

For that reason, careful hands-on cleaning is essential to make sure no fungal hotspots are left inside the appliance.

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

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

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

Ventilation and managing moisture are the main factors in stopping fungi from growing again.

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

Eliminating mould effectively

Now that you know why mould develops and how to remove it fully from a washing machine, it’s clear that prevention matters just as much as cleaning. Simple day-to-day care can extend the life of the appliance and help keep your clothes consistently clean and free from smells.

Start putting these habits into practice today and change the way you look after your laundry area.
