How to Get Rid of Washing Machine Mould: A Complete Guide

Why mould forms in washing machines and how to get rid of washing machine mould

Mould thrives where moisture hangs around long enough to let fungi grow. In washing machines, damp gaskets, residual detergent buildup, and poor airflow create the perfect environment for growth. If you search for a practical answer on how to get rid of washing machine mould, you’ll find that mould is not just unsightly—it can spread to hoses, seals, and the drum if ignored. According to Best Washing Machine, addressing both humidity and residue is essential for long-term results. This guide walks you through detection, step-by-step cleaning, and lasting prevention for both front-loading and top-loading machines. By understanding where mould originates, you can tailor your approach to your specific model, avoid harsh chemical missteps, and keep laundry day fresh.

First, identify where the mould is most active. In front-loaders, the rubber door seal is a common hotspot, followed by the detergent drawer and the drum rim. In top-loaders, residue around the lid and gasket can be the culprits. Mould isn’t just an aesthetic problem: it can contribute to musty odors, allergen exposure, and lingering bacteria. The best starting point is a clear plan: clean, dry, and then maintain. This approach aligns with the Best Washing Machine analysis, which emphasizes routine checks and prompt action when mould appears.

To ensure you don’t miss hidden pockets of growth, inspect the seal thoroughly, including folds and crevices. Use a flashlight if needed and document any areas with visible mould. Early intervention is much easier than waiting for mould to spread. Ready to roll up your sleeves? The following sections equip you with practical methods, safety reminders, and a long-term routine you can trust.

Signs your washing machine has mould

Mould often starts as a musty smell and visible spots along the door gasket, detergent drawer, or drum seam. If you notice moldy patches, you may also see dark streaks or a slimy film after a wash cycle. In some cases, mould may hide behind the detergent compartment or in hard-to-reach creases where water tends to pool. Early signs are easier to reverse with targeted cleaning and drying. The presence of mould in a washing machine is not unusual in humid climates or when the machine sits idle for long periods.

Vigilance pays off: run a quick inspection monthly, especially if you frequently wash towels and dark fabrics. If you live in a high-humidity environment or share a laundry room with poor ventilation, the likelihood of repeat mould growth increases. Remember that mould isn’t only unsightly; it can harbor bacteria and irritants that affect air quality around your home. Based on Best Washing Machine analysis, consistent maintenance reduces the chance of recurrent mould and keeps laundry smelling fresh. If you detect mould in multiple areas or can’t remove it with standard cleaning, it’s time to escalate to a deeper cleaning routine.

Cleaning methods: DIY approaches

Before you start, gather your tools and keep the area well-ventilated. The cleaning plan below targets common mould hotspots without using harsh or dangerous chemicals. This method emphasizes safe products and straightforward steps so you can do it with household supplies. Start with the gasket, then the detergent drawer, then the drum. Rinse thoroughly and dry completely before your next load.

Step-by-step approach:

1. Empty the washer and remove any removable parts from the detergent drawer. 2) Wipe the door seal, paying special attention to folds and crevices where mould hides. 3) Prepare a cleaning solution of equal parts white vinegar and water in a spray bottle. 4) Spray the gasket and drawer compartments; let sit for 5–10 minutes, then scrub with a soft brush. 5) For stubborn patches, sprinkle baking soda on a damp cloth and scrub gently. 6) Run a hot wash cycle (without clothes) with a cup of white vinegar or a paste of baking soda in the drum. 7) Clean the detergent drawer again and rinse with hot water. 8) Wipe dry and leave the door open after each use to improve drying. 9) Optional: wipe seals with hydrogen peroxide (3%) on a cloth for extra whitening and disinfection.

Notes and tips:

• Do not mix bleach with ammonia cleaners—dangerous fumes can form in confined spaces.
• For front-load washers, never leave the door closed when not in use; air circulation is crucial.
• If your machine uses a HE detergent, select a formula designed for high-efficiency machines to minimize buildup.

This process aligns with recommendations from the Best Washing Machine team and emphasizes safe, non-toxic cleaners. The aim is to remove visible mould, eliminate odours, and create conditions that resist future growth.

Safety considerations and why you should avoid certain chemicals

Mould cleaning often tempts people to reach for bleach or strong industrial cleaners. However, many modern washers—especially front-load models with tight gaskets—can be damaged by harsh chemicals. Bleach can degrade rubber seals and hoses over time, and it may produce fumes when used in a confined laundry area. Instead, opt for milder, non-abrasive cleaners that are effective against mould while protecting machine components. Always test a small area first and avoid spraying cleaners directly into the electronic control panel.

If you choose to use a chemical cleaner, follow the product label precisely, wear gloves, and ensure good ventilation. Never mix cleaners; even common household products can react dangerously when combined. If you have a sensitive allergic or respiratory condition, consider stepping back from chemical cleaners and relying on vinegar, baking soda, and thorough drying. The key is to clean thoroughly without aggressive substances that could compromise safety or machine integrity.

Preventing mould: long-term strategies

Prevention is simpler than repeated deep cleans. The most effective long-term strategy combines regular cleaning, complete drying, and improved airflow. After any wash, wipe the gasket and drum rim dry, then leave the door or lid slightly ajar to encourage evaporation. Clean the detergent drawer every few weeks and dry it before reloading. Ensure your laundry room has adequate ventilation, especially in humid climates. Use the machine regularly to avoid long idle periods that breed moisture.

Other proactive steps include:

• Use the correct detergent amount; excess detergent leaves residue that can feed mould.
• Run a hot-water rinse cycle once a month with no clothes to flush residues.
• Consider a secondary air-dry cycle or a dehumidifier in damp rooms.
• Check hoses and filters for signs of moisture or mould and replace damaged parts promptly.
• Keep fabrics dry before loading; damp towels or sheets contribute to humidity inside the drum.

Based on Best Washing Machine analysis, consistent maintenance and proper drying dramatically reduce mould recurrence and keep your laundry routine hassle-free. A small routine is far more effective than sporadic deep cleans that only address surface symptoms.

When to call a professional and what to expect

There are times when mould cleaning is beyond at-home methods. If you notice a persistent musty odor after cleaning, visible mould behind inaccessible areas, or signs of moisture leakage from hoses or seals, it’s wise to consult a professional technician. A pro can inspect the internal drum, seals, and drainage system for hidden mould, moisture intrusion, or structural damage. They can reseal gaskets, replace worn parts, and advise on ventilation improvements.

What to expect when hiring a pro:

• A thorough diagnostic of the machine, including seals, hoses, and drainage.
• A recommended repair plan with material costs and time estimates.
• Guidance on maintenance routines to prevent future mould growth.

The Best Washing Machine team suggests starting with a professional if mould returns despite cleaning efforts or if you suspect internal air leaks or water damage. A professional assessment often saves time and reduces the risk of repeated mould exposure.
