Sarah pulled open her washing machine drawer to add fabric softener and immediately recoiled. Black specks dotted the corners, and that unmistakable musty smell hit her nose. She’d been wondering why her “clean” towels had started smelling strange, but now she knew the culprit.
What started as a few innocent-looking dark spots had quietly transformed into a thriving mould colony. Sarah realized she wasn’t alone – thousands of households battle this exact problem every day, often without knowing the serious health risks lurking in their laundry routine.
The good news? Learning how to remove mould from your washing machine drawer isn’t rocket science, and with the right approach, you can stop it coming back for good.
Why Your Washing Machine Drawer Becomes a Mould Paradise
Your detergent drawer creates the perfect storm for mould growth. After each wash cycle, moisture lingers for hours in those tight corners. Sticky residue from detergents and fabric softeners provides the perfect food source for mould spores.

Most people slam the drawer shut immediately after use, trapping humid air inside. This combination of dampness, limited airflow, and organic material creates what experts call “textbook mould conditions.”
“Mould doesn’t just appear overnight,” explains cleaning specialist Dr. Emma Richards. “It’s been quietly growing in those damp conditions for weeks before you notice the visible signs.”
The health implications go beyond just looking unsightly. Mould releases microscopic spores into the air, which can trigger allergic reactions including sneezing, watery eyes, skin irritation, and respiratory problems. For people with asthma or compromised immune systems, exposure can be particularly problematic.
Once established, mould spores travel through your washing machine’s water system, contaminating hoses, seals, and eventually your clothes. That mysterious musty smell on supposedly clean laundry? It’s often traced back to a mouldy detergent drawer.
The Step-by-Step Guide to Remove Mould From Your Washing Machine
Before diving into the cleaning process, prioritize safety. Never mix different cleaning products, especially bleach and vinegar, as this creates dangerous chlorine gas. Open windows for ventilation and wear rubber gloves if you have sensitive skin.
Here’s your complete mould removal process:
- Remove the drawer completely – Most drawers have a release mechanism about halfway along the runner, often marked “Push” or colored differently
- Dismantle removable parts – Take out any inserts, siphons, or compartment dividers
- Soak in warm, soapy water – Use regular dish soap and let everything soak for 30 minutes
- Scrub thoroughly – Use an old toothbrush to reach corners and crevices where mould hides
- Apply targeted mould treatment – White vinegar or diluted bleach work effectively
- Rinse and dry completely – Any remaining moisture will restart the mould cycle
| Cleaning Solution | Effectiveness | Best For | Safety Notes |
|---|---|---|---|
| White Vinegar (undiluted) | High | Light to moderate mould | Natural, safe for septic systems |
| Bleach (1:10 ratio with water) | Very High | Stubborn, black mould | Ventilate well, avoid mixing with other products |
| Bicarbonate of soda paste | Moderate | Prevention and light cleaning | Completely safe, good for regular maintenance |
| Commercial mould remover | High | Severe infestations | Follow label instructions carefully |
Don’t forget the drawer cavity inside your machine. While the drawer soaks, wipe down the internal housing with a damp cloth and your chosen cleaning solution. This area often harbors hidden mould that recontaminates clean drawers.
Prevention Strategies That Actually Work
Removing existing mould is only half the battle. The key lies in creating conditions where mould simply can’t thrive.
“The most effective prevention is disrupting mould’s three basic needs: moisture, food, and stagnant air,” notes appliance maintenance expert James Thompson.
Your daily habits make the biggest difference:
- Leave the drawer open after each wash – Even a small gap allows air circulation
- Wipe down wet surfaces immediately – Don’t let moisture sit in corners
- Use the correct amount of detergent – Excess soap creates more residue
- Run a monthly maintenance wash – Hot water with no clothes kills lurking spores
- Check and clean rubber seals regularly – These are mould hotspots
Consider switching to powder detergents if you consistently battle mould. Liquid products often leave more sticky residue, providing better growing conditions for spores.
Room ventilation plays a crucial role too. If your washing machine sits in a poorly ventilated utility room or basement, invest in a small fan or dehumidifier. Reducing ambient humidity makes your entire laundry area less mould-friendly.
When to Call in Professional Help
Most household mould situations respond well to DIY treatment, but some scenarios require professional intervention. If you notice mould spreading to walls, extensive black growth that won’t budge with standard cleaning, or if family members experience persistent respiratory symptoms, contact a professional mould remediation service.
“Widespread mould often indicates underlying moisture problems that need addressing beyond just cleaning,” warns building hygiene consultant Dr. Michael Foster.
Professional services use specialized equipment to test air quality, identify moisture sources, and ensure complete mould removal. While more expensive than DIY solutions, professional treatment may be necessary for health and property protection.
Regular maintenance prevents most serious mould problems. Weekly quick wipes and monthly deep cleans keep your washing machine drawer mould-free without professional intervention.
FAQs
How often should I clean my washing machine drawer?
Clean it weekly with a quick wipe-down and monthly with a thorough deep clean to prevent mould growth.
Can I use normal household bleach to remove mould from my washing machine?
Yes, dilute household bleach (1 part bleach to 10 parts water) effectively kills mould, but ensure good ventilation and never mix with other products.
Why does mould keep coming back even after I clean it?
Recurring mould usually indicates you’re not addressing the root cause – moisture and poor ventilation. Leave the drawer open after use and ensure thorough drying.
Is it safe to wash clothes if there’s mould in the drawer?
It’s not ideal as mould spores can transfer to your clothes. Clean the mould first, then run an empty hot wash cycle before resuming normal laundry.
What’s the black stuff in the corners of my washing machine drawer?
Those black spots are typically mould colonies that have established in damp, soapy conditions. They need immediate attention to prevent spread.
Can washing machine drawer mould make me sick?
Yes, mould spores can trigger allergic reactions, respiratory problems, and skin irritation, especially in sensitive individuals or those with compromised immune systems.
