How to Remove Mould from Rubber Seal on Washing Machine
Mould on the rubber seal of your washing machine is a common, yet unpleasant problem. It can cause bad smells, affect washing performance, and even be harmful to your health. The good news is, you can safely and effectively remove mould from your washing machine’s rubber seal with simple tools and household cleaners. Let’s walk through the steps, discuss practical tips, and explore ways to prevent mould from coming back.
Why Does Mould Grow on Washing Machine Seals?
Washing machines provide the perfect conditions for mould to thrive: warmth, moisture, and soap residue. Front-loading machines are especially prone to developing mould because water tends to collect in the folds of the door seal. Over time, this creates a stubborn layer of grime and mildew that can be difficult to remove without a thorough cleaning.
Step-by-Step Guide: Removing Mould from the Rubber Seal
Follow these steps to banish mould from your washing machine’s rubber seal:
1. Gather Your Supplies
Before you start, collect the following:
– Rubber gloves (to protect your hands)
– Soft cloths or sponges
– Old toothbrush (for scrubbing)
– White vinegar or hydrogen peroxide (as a natural cleaning agent)
– Baking soda (for extra scrubbing power)
– Small bowl or spray bottle
– Mild dish soap
– Paper towels
Safety tip: Never mix bleach and vinegar or other cleaning agents, as this can create dangerous fumes.
2. Pull Back the Seal
- Gently pull back the rubber seal so you can see into all the folds and crevices.
- Look for any visible black, grey, or green spots—these are likely mould or mildew.
3. Remove Debris and Wipe Down
- Use a paper towel or dry cloth to remove loose dirt, hair, and debris trapped in the seal.
- This makes cleaning more effective.
4. Apply Your Cleaning Solution
You have a few safe options:
Option 1: White Vinegar Solution
- Mix equal parts white vinegar and water in a spray bottle.
- Spray generously onto the mouldy areas.
- Let it sit for at least 10–15 minutes.
Option 2: Hydrogen Peroxide
- Use 3% hydrogen peroxide.
- Pour or spray onto the affected areas.
- Let it soak for 10–15 minutes.
Option 3: Baking Soda Paste
- Mix baking soda with a little water to make a paste.
- Apply the paste directly onto the mouldy spots.
5. Scrub Away the Mould
- Using your old toothbrush or a soft scrubbing brush, gently scrub the rubber seal.
- Focus on all folds and grooves. The baking soda or vinegar will help loosen the mould.
- For tough spots, reapply your solution and let it sit a little longer before scrubbing.
6. Wipe Clean
- Use a clean, damp cloth to wipe away mould residue and cleaning solution.
- Make sure to remove all cleaning agents from the seal.
7. Dry Thoroughly
- Use a dry towel to get into the seal’s folds and remove any remaining moisture.
- This step helps prevent the return of mould.
8. Run a Cleaning Cycle
- Run your washing machine empty on the hottest cycle.
- Add two cups of white vinegar or a dedicated washing machine cleaner to the detergent drawer.
- This will rinse away any remaining spores or residue from the machine.
Benefits of Regular Maintenance
Cleaning the rubber seal isn’t just about looks—it offers several key benefits:
- Eliminates odours: Mould and mildew can cause a musty smell that transfers to your laundry.
- Improves hygiene: Regular cleaning removes harmful bacteria that could affect your health.
- Extends machine life: Preventing mould and buildup means smoother operation and fewer repairs.
- Keeps laundry fresh: Cleaner seals mean cleaner, fresher-smelling clothes.
Common Challenges (And How to Overcome Them)
Dealing with mouldy washing machine seals isn’t always simple. You might face these issues:
Stubborn Stains Won’t Budge
- Reapply your cleaning solution and let it soak even longer.
- Try switching between vinegar, hydrogen peroxide, or a mild bleach solution (if safe for your machine and environment).
Bad Odours Linger
- Clean your detergent drawer and any accessible internal areas.
- Regularly run a hot empty cycle with vinegar or a washing machine cleaner.
Seal Keeps Getting Mouldy
- Moisture is likely being trapped after every wash.
- Leave the washing machine door open after each cycle to allow air in and moisture out.
- Wipe the rubber seal dry after every use.
Preventing Mould from Returning
Prevention is always easier than constant cleaning. Here are some expert tips:
After Each Wash
- Leave the door open: This allows air circulation and drying.
- Wipe the seal: Quickly dry the rubber after each load.
Weekly Maintenance
- Check for debris: Remove hair, lint, or other residues.
- Inspect for new mould: Catching it early makes it easier to clean.
Monthly Deep Cleaning
- Run a hot cycle: Add vinegar or a special machine cleaner to keep things fresh.
- Clean the detergent drawer: Mould can also hide here and spread to other parts.
Smart Usage Tips
- Use less detergent: Excess detergent can leave a residue, which feeds mould.
- Avoid liquid fabric softener: Use dryer sheets or wool balls instead.
- Wash high-temperature loads periodically: This kills bacteria and prevents buildup.
Challenges with Cleaning (What NOT to Do)
While it’s tempting to use strong chemicals or rough tools, avoid these mistakes:
- Don’t use sharp tools: Knives or abrasive pads can damage the seal.
- Don’t use harsh chemicals: Pure bleach or oven cleaners may degrade the rubber. Always dilute chemicals and follow manufacturer guidelines.
- Don’t ignore manufacturer recommendations: If in doubt, check your washing machine manual.
When Should You Replace the Seal?
If you find the rubber seal is cracked, heavily worn, or the mould is impossible to remove, it may be time for a replacement. Persistent mould deep inside the seal or a lingering odour despite regular cleaning may also signal that replacing the seal is the best option for your machine and health.
Frequently Asked Questions (FAQs)
Can I use bleach to clean the rubber seal?
Bleach can kill mould, but it’s harsh on rubber and may cause damage in the long run. If you use bleach, always dilute it (about one part bleach to four parts water) and rinse thoroughly. Many people prefer natural alternatives like vinegar, which are safer for both you and the machine.
Why does the mould keep coming back after cleaning?
Mould returns when moisture is trapped and the area is not kept clean and dry. Leaving the washing machine door open after every use and wiping the rubber seal can significantly reduce the chance of mould returning.
Is it safe to use my washing machine with mould on the seal?
It’s best to clean the mould as soon as you notice it. Small amounts aren’t usually dangerous, but exposure to mould can irritate people with allergies or sensitivities and cause unpleasant smells to transfer to your laundry.
What is the best cleaning solution for washing machine seals?
White vinegar, hydrogen peroxide, and baking soda are effective natural solutions. For stubborn mould, a diluted bleach solution can be used, but check your machine’s manual first. Always avoid mixing cleaning agents and use only one product at a time.
How often should I clean the washing machine rubber seal?
A quick clean every 1–2 weeks, with a deep clean monthly, is usually enough. Wiping the seal dry after each wash and keeping the door open will reduce the frequency needed for deeper cleans.
Summary
Mould on your washing machine’s rubber seal doesn’t have to be a permanent predicament. By following these simple steps—regular cleaning, using natural cleaning agents, drying the seal, and airing out your machine—you’ll get rid of mould and prevent it from coming back. Regular attention keeps your washer in top shape, your laundry smelling fresh, and ensures a healthier home environment for you and your family.
