If you’ve ever opened your washing machine door and been greeted by a musty odour or unsightly black spots, you’re not alone. Mould is a common problem in washing machines—especially front loaders—and it’s not only unpleasant but can also leave your clothes smelling less than fresh.

Why Does Mould Grow in Washing Machines?

Mould thrives in damp, dark places where there is little airflow. Unfortunately, washing machines—especially those with rubber door seals—provide the perfect environment. Leftover detergent, fabric softener, and trapped moisture create a breeding ground for mould and mildew. Regular cleaning is essential to break this cycle and protect your laundry.

How to Clean Mould from Your Washing Machine: Step-by-Step

Follow these simple steps to effectively clear out mould and freshen up your washer.

1. Gather Your Cleaning Supplies

You’ll need:

• Rubber gloves
• Old towels or microfiber cloths
• Toothbrush or soft brush
• White vinegar (or bleach if preferred)
• Baking soda
• Spray bottle

2. Inspect Key Areas for Mould

Focus on:

• The rubber door seal (most common site)
• Detergent and fabric softener dispensers
• The drum interior

Look for black or dark spots, as well as any musty smells.

3. Clean the Washing Machine Seal

The rubber door seal traps water and is a hotspot for mould.

1. Put on rubber gloves.
2. Mix equal parts white vinegar and water in a spray bottle.
3. Pull back the seal gently to inspect hidden areas.
4. Spray the mixture generously under the seal, on the surface, and inside any folds.
5. Use a cloth or an old toothbrush to scrub away visible mould.

6. Wipe down the area with a clean cloth.

7. Tip: For stubborn spots, sprinkle baking soda directly onto the mould before scrubbing with vinegar. Let it bubble and sit for 10-15 minutes before wiping.*

4. Clean the Detergent Dispensers

Mould can also settle in drawers where detergent and softeners are added.

1. Remove the dispenser drawer completely (check your manual to see how).
2. Soak it in hot, soapy water for 10-15 minutes.
3. Scrub all surfaces, especially corners, with a toothbrush.
4. Rinse thoroughly and dry before returning it to the machine.

5. Clean the Drum and Run a Cleaning Cycle

To kill lingering spores and deodorize the washer:

1. Pour 2 cups of white vinegar (or 1 cup of bleach) directly into the drum.
2. Sprinkle half a cup of baking soda into the drum as well.
3. Run the machine on the hottest, longest cycle (without laundry).

4. Once the cycle is complete, leave the door open to air dry.

5. Note: Never mix vinegar and bleach together—choose one, as mixing can release harmful fumes.*

6. Wipe Down the Exterior

While mould growth on the outside is rare, it’s wise to clean all surfaces.

• Use a damp cloth and a mild cleaner to wipe the outside.
• Pay attention to buttons, handles, and any moisture-prone crevices.

Benefits of Cleaning Mould from Your Washing Machine

• Fresher laundry: Eliminates musty odours that can cling to clothes.
• Healthier environment: Reduces exposure to allergens and mould spores.
• Longer machine lifespan: Prevents build-up that could affect performance.
• Improved appearance: Removes unsightly mould or mildew spots.

Challenges & Common Mistakes

• Ignoring hidden mould: Many people only wipe what they see, leaving behind hidden infestations.
• Using the wrong products: Abrasive cleaners can damage seals; stick to gentle yet effective solutions like vinegar, baking soda, or diluted bleach.
• Closing the door after each wash: This traps moisture, giving mould a chance to grow.
• Forgetting regular cleaning: One deep clean isn’t enough; regular maintenance is key.

Best Practices & Prevention Tips

Keep mould at bay with these proactive steps:

Regular Maintenance

• Wipe down the door seal after every use to remove moisture.
• Leave the door and detergent drawer open post-wash to allow air circulation.
• Run a hot, empty wash with vinegar or machine cleaner once a month.
• Clean the detergent drawer and filter frequently.

Laundry Habits

• Avoid using too much detergent or fabric softener—excess can lead to residue build-up.
• Remove washed laundry promptly to prevent dampness inside the drum.

Inspect for Leaks

• Check hoses and seals regularly to ensure no water is leaking or pooling.

When to Seek Professional Help

If mould persists despite regular cleaning, or if you spot heavy black spots in hard-to-reach areas, it may be time to call in a professional. Persistent issues could signal a more serious problem that requires specialized care or parts replacement.

Frequently Asked Questions (FAQs)

1. How often should I clean my washing machine to prevent mould?
Ideally, perform a thorough cleaning—including the seal, drum, and detergent drawer—at least once a month. Wipe down visible moisture and leave the door open after every wash for best results.

2. Is vinegar or bleach better for cleaning washing machine mould?
Both are effective, but vinegar is safer for most washing machines and environmentally friendly. Use bleach sparingly, as it’s powerful but can damage rubber seals if overused. Never mix the two in the same cleaning cycle.

3. Can mould in my washing machine make me sick?
Yes. Mould releases spores that can cause allergies, respiratory issues, or skin irritation, particularly in sensitive individuals. Keeping your washer clean reduces these health risks significantly.

4. Why is mould more common in front-loading machines?
Front-loaders have tight rubber seals to prevent leaks, which also trap moisture and soap residue. Their horizontal design makes it easier for water to collect—providing an ideal environment for mould growth.

5. Are there commercial products made for washing machine cleaning?
Yes, there are washing machine cleaning tablets and liquid cleaners designed to target mould, mildew, and odours. These can be helpful in addition to routine cleaning with household products.
