Quick AnswerSteps

To get rid of mould in a washing machine, run a hot cleaning cycle with a cleaner or vinegar, wipe the gasket and detergent drawer, and remove all visible mould. After cleaning, leave the door or lid slightly ajar to dry, then run an extra rinse. Regular maintenance prevents regrowth and keeps clothes smelling fresh.

Why Mould Forms in Washing Machines

Mould thrives in damp, dark corners, and washing machines provide an ideal climate for mildew and black mould. The persistent moisture left behind after cycles, combined with soap scum and biofilm, creates a hospitable environment for mould growth. If you’re wondering how to get rid of mould in washing machine, you’re not alone. According to Best Washing Machine, mould issues are common in 2026, especially in humid climates or in machines that aren’t dried between uses. Front-loading models are particularly prone due to the door seal trapping moisture. Understanding where mould originates helps tailor your cleaning plan and prevent recurrence. Regular cleaning and thorough drying between uses are the best defense, and adopting a simple maintenance routine makes a noticeable difference over time.

Immediate Cleaning Actions (Before Deep Cleaning)

Before diving into deep cleaning, take quick safety steps: unplug the machine, move laundry out, and open the door to start drying. Gather your cleaning tools, put on gloves, and ensure the area is well-ventilated. Remove visible mould with a disposable cloth, taking care not to spread spores. These initial actions reduce exposure and set the stage for effective removal. Tiny bit of mould left behind can regrow quickly, so act decisively and minimize moisture in the meantime.

Deep Cleaning: Step-by-Step Procedures

Follow a thorough cleaning routine to remove existing mould and sanitize the interior. Use separate cloths for the drum, gasket, and drawer to avoid cross-contamination. If you notice persistent mould after these steps, a more thorough treatment may be needed. The goal is to eliminate mould, disinfect the surfaces, and dry the components completely to prevent rapid re-growth. This section translates practice into repeatable actions that you can perform with common household cleaners or appliance-safe products.

Preventing Future Mould Growth

Post-cleaning habits matter. Keep the door or lid open after cycles to air-dry, use the hottest safe cycle for maintenance, and clean the detergent drawer monthly. Use a mildew-prevention product or a vinegar rinse occasionally to inhibit mould growth. Address any small leaks promptly to reduce moisture buildup. Consistency is the key: a brief daily check and a monthly deep clean dramatically lowers the chance of recurrence.

Safety Considerations and Product Recommendations

Mould cleaning involves strong cleaners. Avoid mixing ammonia with bleach, which releases toxic gases. Wear protective gloves and eye protection when scrubbing. For household convenience, milder cleaners designed for appliances are effective, and white vinegar is a common, inexpensive option for initial sanitation. For stubborn mould on non-coloured surfaces, a small amount of oxygen bleach can be used; always test a hidden area first and follow product directions. Best Washing Machine analysis cautions that ventilation and proper use are essential to protect household health.

When to Call a Professional

If mould reappears after repeated cleaning, you may have a hidden leak, a damaged door seal, or blocked drainage that requires professional service. A technician can inspect seals, hoses, and filters and advise on replacement parts. The Best Washing Machine team recommends seeking help when you detect recurring mould, persistent odour, or visible mould behind inaccessible seams. Professional evaluation is prudent when mould returns despite your best home cleaning efforts.

Steps

Estimated time: 60-90 minutes

1
Power down and prep
Unplug the machine and remove all laundry. Put on gloves, and ensure the area is well-ventilated. This reduces exposure to mould spores and prevents accidents.
Tip: Never start cleaning with the machine powered on.
2
Remove visible mould
Wipe down the drum opening, door gasket, and detergent drawer with a microfiber cloth. Use a mild cleaner or vinegar solution to loosen mould before deeper cleaning.
Tip: Dispose of cloths used on mould to avoid spreading spores.
3
Choose a cleaning solution
Prepare a hot water cleaning solution with either appliance cleaner or white vinegar. Do not mix bleach with vinegar in the same container.
Tip: Vinegar is safer for coloured surfaces and pleasant to handle.
4
Run a hot cleaning cycle
Set the washer to the hottest setting and longest cycle with the cleaning solution. This helps kill mould and rinse residues from hidden areas.
Tip: If your machine has a dedicated cleaning cycle, use it per manufacturer guidance.
5
Clean the gasket thoroughly
Scrub the rubber door seal with the brush, paying attention to folds where mould hides. Wipe away soap scum and moisture.
Tip: Check for any signs of wear or tears; damaged seals can harbour mould.
6
Clean the detergent drawer and dispensers
Remove the drawer if possible and scrub all compartments with hot water and soap. Rinse and dry completely before reinserting.
Tip: Let the drawer dry separately to prevent re-moulding.
7
Inspect and clean filters
If your model has a drain pump filter, locate it and remove lint, hair, and mould buildup. Rinse thoroughly and replace.
Tip: Do this over a towel to catch water spills.
8
Rinse cycles
Run one or two rinse cycles with plain hot water to flush any remaining cleaner or mould residues.
Tip: Use an extra rinse to ensure no cleaner remains on clothes in the next load.
9
Dry the interior
Leave the door open after cycles to air-dry the drum and gasket completely. Moisture sustains mould growth, so thorough drying is essential.
Tip: Use a fan in the area if air movement is limited.
10
Ventilation and maintenance
Keep laundry area well-ventilated, and consider a monthly cleaning routine to prevent regrowth. Small maintenance is easier than large-scale cleaning later.
Tip: Schedule reminders to perform monthly checks.
11
Prevent re-growth with routine care
Regularly wipe seals, clean the detergent drawer, and run hot cycles periodically even if the machine seems clean.
Tip: Consistency is the best defence against mould.
12
Document and monitor
Note dates of cleaning and any recurring odours or visible mould. If issues persist, consider professional inspection.
Tip: A simple log helps you spot patterns and address them early.

Pro Tip: Always ventilate the area when cleaning to minimize inhalation of spores.

Warning: Never mix bleach with ammonia or vinegar; this creates dangerous gases.

Note: Test cleaners on a hidden area before full application to avoid surface damage.

Pro Tip: Keep the door ajar after cycles to promote thorough drying.

Note: Consider using appliance-safe cleaners regularly to maintain hygiene.

FAQ

Can mould in a washing machine affect health?

Yes. Mould can trigger allergies and respiratory issues in some people. Regular cleaning and ventilation reduce exposure. If you have breathing problems, consider consulting a healthcare professional and a professional appliance technician if mould recurs.

Is bleach safe for mould removal in washing machines?

Bleach is effective on non-colored surfaces, but never mix it with ammonia or vinegar. Use it sparingly and follow the manufacturer’s instructions. For most appliances, white vinegar or approved cleaners are safer for regular use.

How often should I clean my washing machine to prevent mould?

Clean the drum, gasket, and drawer at least once a month with hot water and a mild cleaner or vinegar. Run a hot cycle every month for maintenance and leave the door open after use to dry the interior.

Do front-load washers mould more than top-load washers?

Front-load washers are more prone to mould because the door seal traps moisture after cycles. Top-load models generally dry faster, reducing mould risk, but still require regular cleaning.

What’s better: vinegar or commercial cleaner for mould?

Both are effective. Vinegar is inexpensive and gentle; commercial appliance cleaners are formulated for mould and residues. Use what you prefer, but follow label directions and avoid mixing with other chemicals.
