How to Remove Mould from a Washing Machine Drawer

That small patch of mould in the detergent drawer does more than look unpleasant: it can gradually spread through the appliance, taint your washing and even affect the air you breathe at home. The key is dealing with it properly and promptly, then adopting a few easy routines that stop it coming back.

Why mould loves the washing machine drawer

The detergent drawer is a near-perfect environment for mould. After each cycle it stays damp for ages, it holds on to sticky remnants of detergent and fabric conditioner, and many people slide it shut as soon as the wash ends. Limited airflow plus constant moisture plus soap residue is exactly what mould thrives on.

Mould in the drawer is not just ugly; it can affect the air you breathe and the clothes you wear.

As mould develops, it sheds tiny particles known as spores. For anyone who’s sensitive, these can set off sneezing, a streaming nose, red or itchy eyes and sometimes skin irritation. In more humid properties, people also mention congested sinuses, coughing or a stinging sensation in the eyes.

Once the mould has established itself in the drawer, rinse water can transport spores further into the machine. They may reach the hoses, the rubber door seal and even circulate into the air of a small utility or laundry room. If your laundry smells “clean” but has a musty edge, the problem is often the forgotten drawer rather than the drum.

Safety first: one cleaning mistake to avoid

Harsh cleaners can feel like the safest bet, but that confidence is exactly what leads many people into trouble. A common error is combining bleach with acidic products such as vinegar. Mixed together, they can give off chlorine gas, which can irritate the eyes, nose and throat even at relatively low levels.

Never mix bleach and vinegar. Stick to one type of cleaner at a time and ventilate well.

Before you begin, open a window or run an extractor fan. If your skin is easily irritated, wear rubber gloves. The cleaning itself is straightforward; the real danger is creating an improvised chemical mix, not the elbow grease.

How to remove the washing machine drawer without breaking it

If you’ve never removed the drawer before, it can seem jammed, as though it’s built into the machine. With most modern appliances, it isn’t. Typically there’s a small release catch about halfway along the drawer runner, sometimes labelled “Push” or highlighted in a different colour.

Pull the drawer out as far as it will go and find the catch. Keep the drawer straight with one hand so it doesn’t twist. With the other hand, press the catch and ease the drawer directly towards you. It should come free without forcing it. If it won’t budge, make sure the catch is fully depressed and try again with a level, straight pull rather than lifting upwards.

A seven‑step cleaning routine with vinegar and soapy water

White vinegar is widely used at home for odours and detergent build-up. How well it tackles mould can depend on the mould type, but as a general cleaning helper it’s effective at loosening grime and refreshing surfaces.

Step-by-step method

• Fill a bowl or sink with lukewarm water and a squirt of washing-up liquid.
• Add around two cups of white vinegar (roughly 480 ml) to the water.
• Put the drawer into the mixture and leave it to soak for 5–10 minutes.
• Scrub the broad surfaces and corners with a sponge, especially where detergent turns into a paste.
• Use an old toothbrush for the runners, grooves and tight recesses.
• Rinse well with clean water, then check the drawer in good light: if dark specks remain, scrub those spots again.
• Dry the drawer thoroughly with a cloth and leave it out in open air for a while before refitting it.

The job looks tedious from a distance, but once you’ve done it, the fresher smell is immediate.

From start to finish, this usually takes under 20 minutes. The improvement in smell can be noticeable, particularly in smaller homes where the washing machine sits in a kitchen or hallway.

What experts say about moisture control

Mould professionals tend to repeat one basic principle: damp areas should be dried within 24 to 48 hours. Leave moisture longer than that and mould finds it much easier to get established. The washing machine is no different.

Area	Drying target	Risk if left wet
Detergent drawer	Fully dry between wash days	Mould patches and stale odours
Door seal	Wiped after heavy washes	Black spots and slime build-up
Floor around machine	Puddles dried in under 48 hours	Hidden damp, mould on skirting and walls

Manufacturer-approved habits that actually work

Most manufacturers recommend a surprisingly simple habit: give the machine a chance to dry out. Rather than shutting everything immediately, leave the door and the detergent drawer slightly open once the cycle ends. That small gap helps moisture escape instead of lingering inside.

They also typically suggest a monthly deep clean of the drawer and a quick look over the rubber door seal. It may sound obvious, but together these steps reduce the three things mould wants most: moisture, residue and darkness.

Quick daily habits to keep the musty smell away

• Leave the door and drawer ajar after each wash: this prevents still, humid pockets of air from building up.
• Clean the drawer once a month: less residue means fewer places for mould to take hold.
• Dry splashes and small puddles within 24–48 hours: less standing water means less chance of mould.
• Use less detergent and softener: using too much leaves a sticky film that clings to surfaces.

When mould keeps coming back fast

If you clean the drawer and fresh mould appears again within a few days, something isn’t drying properly. Begin by checking whether water collects in the compartment after a cycle. A partial blockage in the cavity behind the drawer can stop water draining away.

Also inspect the rubber door seal and the area around the drawer opening. If they’re persistently damp or feel slimy, airflow is likely inadequate. Often, simply pinpointing what never dries and then improving ventilation or drying more thoroughly is enough to break the regrowth pattern.

When to call in stronger measures or professional help

For minor surface mould in the drawer, soapy water and vinegar will usually do the job. If patches are stubborn and keep returning across multiple parts of the machine, it may be worth using a specialist washing machine cleaner or a product labelled for household mould, following the instructions closely.

If the room smells strongly musty even when the machine is off, or you can see mould spreading to nearby walls or skirting boards, the issue may extend beyond the appliance. Ongoing damp beneath or behind the machine can damage flooring and plaster. In that situation, a plumber or damp specialist can check for slow leaks, poor drainage or hidden water damage.

Helpful concepts: spores, biofilm and indoor air

Three simple concepts explain why a few black marks in a drawer matter. First are spores. Mould doesn’t just sit on a surface; it releases microscopic particles that drift through the air. These are what you inhale and what can seed new growth elsewhere.

Second is biofilm. The slippery coating that forms in drawers and seals is a combination of detergent residue, minerals and microbes. Once biofilm is present, it can shelter mould and bacteria, making them tougher to shift. Regular scrubbing removes that protective layer and leaves a smoother, less hospitable surface.

Third is indoor air quality. One small patch of mould in a drawer is unlikely to seriously harm a healthy adult, but in a well-sealed home with several damp areas, the cumulative impact can be noticeable. Households with asthma, allergies or babies may find that simple steps-airing the drawer and drying the seal-bring gradual, real improvements in comfort.

With that in mind, cleaning the washing machine drawer isn’t just cosmetic. It’s a practical step towards a home that feels less damp and less stale-and washing that smells genuinely clean when it comes out of the drum.
