Why it matters
Detergent, fabric softener and damp air build up inside the drum, drawer, seal and filter. That build-up causes musty smells, grey marks on clothes and poor washing. A monthly deep clean clears it — no special products needed.
You will need
- 2 cups (500 ml) white vinegar
- 1/2 cup (about 100 g) baking soda
- 2 microfibre cloths and an old towel
- Soft brush or old toothbrush
- Small bowl, shallow tray and gloves
- Optional: washing machine cleaner tablet, if your manual recommends one
Safety first
- Never mix vinegar with bleach — the mix makes harmful gas
- Turn off and unplug the machine before cleaning the filter
- Hot water will drain from the filter hose — go slowly
- Check your manual first: some makers advise against vinegar in their machines. If so, use a machine cleaner instead.
Before you start
- Empty the drum completely and check pockets of the last load are not left inside
- Run the tap / check the machine can fill and drain normally
- Put an old towel on the floor in front of the machine
- Open windows or run ventilation — vinegar smells strong while it works
Step by step — the deep clean
1. Clean the detergent drawer
- Pull the drawer out fully. Press the release tab (usually in the middle) and slide it free.
- Soak the drawer and its removable parts in warm, soapy water for 15 minutes.
- Scrub mould and residue from every corner with the soft brush, rinse well and dry.
- Wipe inside the drawer housing in the machine with a damp cloth, then slide the dry drawer back in.
2. Clean the rubber door seal (front-loaders)
- Pull the folds of the seal back gently and remove any coins, hair clips and lint.
- Wipe all the way around inside the folds with a cloth dampened with a 1:1 mix of water and white vinegar.
- For black mould spots, press a vinegar-dampened cloth onto the spot for 10 minutes, then scrub gently with the soft brush.
- Wipe again with a clean cloth dampened with plain water, then dry the folds thoroughly.
Top-loaders: skip the seal. Instead, wipe under the lid rim, around the agitator base (if fitted) and the top edge of the drum.

3. Run two empty hot cycles — drum clean
- Cycle 1 — vinegar: Pour 2 cups white vinegar into the detergent drawer (front-load) or directly into the drum (top-load). Run the longest, hottest empty wash.
- Cycle 2 — baking soda: Sprinkle 1/2 cup baking soda directly into the drum. Run another long, hot empty wash.
- Do not put vinegar and baking soda in together — they neutralise each other. Two separate cycles clean far better.
- When the second cycle ends, wipe the drum dry and leave the door or lid open.
4. Clean the drain pump filter
- With the machine off and unplugged, open the small flap at the bottom front (most front-loaders).
- Put the shallow tray and towel underneath. Unscrew the drain hose cap first and let the water run out slowly.
- Unscrew the filter, pull out lint, coins and hair, rinse the filter under the tap and wipe the housing.
- Screw the filter back in firmly, close the hose cap and the flap. A loose filter leaks.
Top-loaders often have lint filters inside the drum or agitator — lift them out, rinse them and click them back in. Check your manual for the location.
Finish, then keep it fresh
5. Exterior and final wipe
- Wipe the door glass inside and out with a damp microfibre cloth
- Wipe the control panel with a barely damp cloth — keep water out of buttons and dials
- Wipe the top and sides, and clean behind the machine if you can reach safely
- Leave the door or lid and the detergent drawer open to dry completely

Monthly deep-clean checklist
- Detergent drawer soaked, scrubbed and dried
- Door seal folds wiped and dried (or lid rim on a top-loader)
- Empty hot wash with vinegar completed
- Empty hot wash with baking soda completed
- Drain pump / lint filter emptied and rinsed
- Drum, door glass and exterior wiped dry
- Door, lid and drawer left open to air
Good habits — every week
- Leave the door or lid open after every wash so the drum dries
- Wipe the seal dry after the last wash of the day
- Use the right detergent dose — too much leaves residue and smells
- Take wet laundry out promptly; do not leave it sitting overnight
- Once a week, run an empty hot rinse if you mostly wash on cold
If something still smells or looks wrong
- Musty smell returns quickly — Repeat the two hot cycles, clean the filter, and leave the door open between washes for a full week
- Black mould on the seal — Repeat the vinegar compress. If the seal is cracked or the mould will not shift, replace the seal
- Grey marks on clothes — Cut detergent dose, clean the drawer, and run the baking soda cycle again
- Machine drains slowly — Clean the drain pump filter again and check the drain hose is not kinked
Tip: Note the date of each deep clean here. Monthly is enough for most homes — do it every 2 weeks if you wash daily or mostly on cold cycles.
