How to Clean a Washing Machine: UK Guide

Your washing machine might clean your clothes, but who cleans the machine? Over time, detergent residue, fabric softener, limescale, and trapped dirt can build up inside — leading to bad smells, mould, and a less efficient wash.

Here’s how to give your washing machine a proper clean — inside and out.

Step 1: Clean the Detergent Drawer

Pull out the detergent drawer as far as it will go (check your manual – most will let you fully remove it by pressing a tab or lifting slightly).

Soak it in warm water with a splash of washing-up liquid.
Use an old toothbrush or bottle brush to scrub out corners, especially behind the softener section.
Rinse well and dry before popping it back in.

Tip: Also clean the cavity where the drawer slides in — mould loves to hide there.

Step 2: Clean the Drum

Even though the drum looks clean, there’s often hidden buildup.

Run an empty cycle on the hottest setting (usually 90°C or a ‘drum clean’ cycle if your machine has one).
Add white vinegar or a washing machine cleaner tablet to the drum.
For extra cleaning power, add bicarbonate of soda to the detergent drawer.

This helps remove limescale, residue, and bacteria that cause unpleasant smells.

Step 3: Clean the Rubber Seal

That rubber door seal is a common culprit for mould and grime.

Pull it back gently and wipe with a cloth soaked in white vinegar or diluted bleach.
Use a toothbrush for stubborn bits.
Dry thoroughly with a clean cloth.

If you notice black mould that won’t shift, you may need a dedicated mould remover.

Step 4: Clean the Filter (Bottom Front Panel)

Most washing machines have a drain pump filter hidden behind a flap at the bottom front.

Place a towel and shallow tray underneath before opening — water will spill out.
Unscrew the filter and remove any fluff, coins, hair clips or surprises.
Clean under the tap, then screw it back in firmly.

Warning: Always turn off the machine and unplug it before doing this bit.

Step 5: Wipe the Outside

Use a damp cloth and a small amount of mild detergent to clean the control panel and door. Avoid spraying anything directly onto the machine — spray the cloth instead.

Tips to Keep Your Washing Machine Clean

Leave the door and drawer open between washes to let air circulate and prevent mould.
Use less detergent — more isn’t better. Overdosing causes residue build-up.
Run a hot wash monthly, especially if you normally use cooler cycles.
Wipe the seal and door glass regularly.

Final Thought

Cleaning your washing machine every few weeks helps it last longer, smell fresher, and clean your clothes properly. It only takes a bit of effort — but saves you from mystery smells, mouldy socks, and unexpected breakdowns.
