How to Clean Your Washing Machine (Front and Top Loader): The Australian Guide

If your washing machine smells musty, leaves grey flecks on clothes, or has black spots creeping around the door seal, it isn't broken — it's dirty. A washing machine cleans itself last, and in Australia's humid coastal cities it loses that battle faster than almost anywhere. The good news: a proper clean takes about 20 minutes a month, and everything you need is probably already in the cupboard.

Why washing machines get dirty (and smelly)

Three habits create the problem, and most of us have all three:

• Cold washes. Brilliant for your power bill and your clothes, but a cold cycle never gives the machine the hot flush that dissolves built-up residue.
• Too much detergent. Surplus detergent doesn't rinse away — it coats the drum, the outer tub and the door seal, and that film is exactly what mould and bacteria feed on. (It's also the main reason towels smell musty after washing.)
• Closing the door between loads. A sealed, damp drum in a warm Queensland or Sydney laundry is a mould incubator.

Cleaning a front loader (the 20-minute version)

1. The gasket first. Peel back the rubber door seal and wipe inside the fold with a cloth dampened in warm soapy water, or equal parts white vinegar and water for mouldy patches. An old toothbrush reaches the grooves. This fold is where 90% of the smell lives.
2. The dispenser drawer. Most drawers pop out completely (check for a release tab). Soak it in warm water, scrub the softener slot — usually the gunkiest corner — and wipe the cavity it slides into, which hides more mould than the drawer itself.
3. The hot maintenance cycle. Run the machine empty on its hottest, longest cycle with 2 cups of white vinegar in the drum, or a manufacturer-approved machine cleaner. If your machine has a dedicated "tub clean" program, use that.
4. The pump filter. Behind the little hatch at the bottom front. Put a towel down, unscrew slowly, and be ready for a cup or two of water — plus the missing hair ties, coins and the odd sock. Clogged filters are behind most drainage errors and end-of-cycle smells.

One honest caveat: a few manufacturers advise against frequent vinegar cycles because acid can age rubber seals over many years. If yours does, alternate with a branded machine cleaner or plain hot cycles — the routine matters far more than the product. And never mix vinegar and bleach in any cleaning job: the combination releases toxic chlorine gas.

Cleaning a top loader

Top loaders skip the gasket problem but build up residue on the agitator and under the rim:

1. Fill with the hottest water setting, add 2 cups of white vinegar, agitate for a minute, then pause and let it soak for an hour before finishing the cycle.
2. Wipe under the top rim with a vinegar-damp cloth — run a finger under there and you'll see why.
3. Empty the lint filter (usually a mesh pocket on the agitator or inner rim) every few loads, not once a year.

Keeping it clean: five habits that beat any deep clean

1. Leave the door and drawer open between washes so the drum dries out. If little kids or curious pets rule that out, at least prop it for the first few hours.
2. Dose correctly, every load. This is the big one. Overdosing feeds the machine the residue that mould grows on. Pre-measured formats make it automatic — with laundry detergent sheets it's half a sheet for an everyday load, a full sheet for a big or heavily soiled one, and the sheet dissolves completely in hot or cold water, so there's no undissolved surplus left behind to coat the drum.
3. Run one hot cycle a month, even if every wash in between is cold.
4. Skip fabric softener. It's the stickiest residue in the machine and the biggest contributor to gasket grime. Well-dosed detergent leaves towels softer than softener buildup ever will.
5. Don't leave wet washing sitting. In an Australian summer, an hour in a sealed drum is enough to start the smell cycle all over again.

How often is enough?

Monthly for the maintenance cycle and gasket wipe, every few months for the pump filter, and a full deep clean at the change of each season — which makes the start of spring the perfect calendar reminder. (It's step one in our Australian spring cleaning checklist.)

A clean machine also simply washes better: no grey flecks, no transferred smells, and detergent that works on your clothes instead of fighting old residue. If you're fixing the dosing half of the equation, a pack of 40 pre-measured sheets covers up to 80 loads and is backed by our 30-day money-back guarantee — and any 2 packs across the range save 15%, any 3 save 20%, any 4 or 5 save 25% and any 6 or more save 30%, automatically.
