How to Get Mould Off Rubber in Your Washing Machine
Dealing with mould on the rubber seal of your washing machine can be frustrating—and a little gross. Most front-loading washing machines have a rubber gasket or seal that keeps water from leaking out. Unfortunately, this same seal is the perfect hiding spot for mould and mildew, thanks to the warm, moist environment inside the washer. But with a few simple steps, you can banish mould and keep your washing machine fresh and clean.
Why Does Mould Grow on Washing Machine Rubber?
The rubber seal, often called the gasket, is designed to stop water from leaking. However, it also traps moisture, laundry detergent, fabric softener, and tiny bits of dirt. These leftovers create the perfect condition for mould and mildew to thrive. If not cleaned regularly, you may notice:
- Black or grey spots along the rubber
- An unpleasant, musty smell from your washer
- Clothes coming out smelling less than fresh
Step-by-Step Guide: Removing Mould from Washing Machine Rubber
What You’ll Need
Before you begin, gather these supplies for a thorough clean:
- Rubber gloves (protect your hands)
- Microfiber cloths or old towels
- A toothbrush or soft brush
- An empty spray bottle
- White vinegar or hydrogen peroxide (natural mould removers)
- Baking soda (optional, for extra scrubbing power)
- Mild liquid detergent
- Water
1. Safety First
Always unplug your washing machine before cleaning. Wear rubber gloves to protect your skin from mould and cleaning products.
2. Wipe Down the Seal
Open the door wide and carefully pull back the rubber seal. Use a dry cloth to wipe away any visible gunk, hair, or lint. This step helps remove loose dirt and gives you a clear view of the mould growth.
3. Apply Mould Remover
Mix equal parts white vinegar and water in a spray bottle. If you’re using hydrogen peroxide, you can use it undiluted. Spray the solution generously onto the mouldy areas of the seal, making sure to get into all the folds and crevices.
- Let the solution sit for at least 10-15 minutes. This gives it time to break down mould and mildew.
4. Scrub Away the Mould
Take a soft brush or toothbrush and gently scrub the rubber seal. Pay special attention to hidden folds where mould likes to hide.
- For stubborn stains, sprinkle a small amount of baking soda onto your brush and scrub again. The gritty texture helps lift mould without damaging the rubber.
5. Rinse and Dry
Use a clean, damp cloth to wipe away all the cleaning solution and mould residue. It’s important to remove every trace—leftover cleaner or mould can damage the seal or make the problem worse.
- Finally, dry the seal thoroughly with a towel. A dry seal is much less likely to develop mould again.
6. Run a Cleaning Cycle
To finish, run an empty Hottest wash cycle on your machine. Add two cups of white vinegar or a washing machine cleaner to the drum (not the rubber seal). This helps clean out any spores or debris loosened during scrubbing and refreshes the inside of your machine.
Practical Tips and Best Practices for Mould Prevention
Keeping mould at bay is much easier than having to remove it. Here are some expert-backed tips to stop mould from returning:
- Leave the Door Open: After every wash, leave your washing machine door slightly open. This allows air to circulate and the interior to dry out completely.
- Dry the Seal After Use: Keep an old towel handy to quickly wipe down the rubber gasket after each wash.
- Clean Weekly: Make it a habit to check under the seal for trapped debris and wipe it out at least once a week.
- Use the Right Detergent: Too much detergent or fabric softener can build up inside the machine and contribute to mould growth. Use high-efficiency detergent and measure carefully.
- Run Monthly Maintenance Washes: Give your machine a “service wash” with hot water and a cup of white vinegar or a store-bought machine cleaner to help kill hidden mould spores.
- Check for Drain Issues: Ensure your washer drains fully after each cycle, as standing water invites mould.
Benefits of a Mould-Free Washer
A clean washing machine does more than just smell fresh:
- Cleaner Clothes: Laundry will come out smelling and looking better.
- Longer Appliance Life: Regular cleaning prevents damage to seals and extends the washer’s lifespan.
- Better Health: Less mould means fewer allergens for your household to breathe in.
- Greater Efficiency: A clean washer runs more efficiently, saving water and energy.
Possible Challenges and Solutions
Stubborn Mould That Won’t Budge
- Try Commercial Mould Removers: For particularly tough mould, you can use a gentle, store-bought mould remover designed for washing machines. Always read instructions and test a small area first.
- Repeat Treatment: Sometimes you’ll need to repeat the cleaning process two or three times to get rid of all the mould.
Damaged or Worn Seals
- Replace the Gasket: If the rubber seal is badly stained, cracked, or smells persistently, consider replacing it. Most washers allow for replacement parts—check your manufacturer’s instructions.
Summary
Mould on the rubber seal of your washing machine is common but can be managed with a little time and attention. Regular cleaning with household products like vinegar and baking soda, combined with a few smart habits, can keep your machine fresh, safe, and mould-free. Consistency is key—prevention is easier than cure.
Frequently Asked Questions (FAQs)
1. Why does mould keep coming back on my washing machine seal?
Mould returns if moisture, detergent, or dirt is left behind. It thrives in dark, damp conditions. Leaving the door open, drying the seal, and regular cleaning are essential to break the cycle.
2. Can I use bleach to clean the rubber seal?
You can use diluted bleach for stubborn mould, but be careful—bleach can degrade rubber over time and release harmful fumes. Natural solutions like vinegar or hydrogen peroxide are safer for regular use.
3. Is mould on my washing machine seal dangerous?
Small amounts typically aren’t a major health risk but can worsen allergies or asthma. Large or persistent mould growth should be addressed quickly to protect your health and your machine.
4. How often should I clean my washing machine seal?
Wipe the seal dry after every use and give it a thorough clean with vinegar or detergent at least once a month. More frequent cleaning may be needed in humid environments.
5. When should I replace the washing machine seal?
If mould stains don’t come out, if the seal is cracked, torn, or smells persistently foul even after cleaning, it’s time to replace the gasket. Replacement parts are available from most manufacturers.
By following these steps and tips, you’ll keep your washing machine—and your laundry—smelling fresh and clean!
