How to Remove Black Mould in Washing Machine Seal

Why Does Black Mould Love Your Washing Machine Seal?

Let’s be real: your washing machine’s door seal is basically mould kingdom prime real estate. The combination of warm, damp conditions and detergent residue creates the perfect breeding ground. If you’ve ever opened your washer and smelled that funky, unmistakable scent—or even seen those pesky black spots lurking in the folds—you know this battle is one worth winning.

Mould isn’t just an aesthetic ouchie; it can cause musty odours, damage rubber seals, and potentially trigger allergies. So, how do you evict this unwelcome tenant without dismantling your entire laundry setup? Buckle up, because we’ve got a thorough, step-by-step guide to wipe out black mould from your washing machine seal for good.

Gear Up: What You’ll Need to Fight the Fungus

Before diving in, grab these trusty sidekicks:

• Protective gloves (mould and cleaning agents don’t play nice with skin)
• Microfibre cloths or paper towels
• Soft toothbrush or small scrub brush
• Baking soda
• White vinegar (gentler cleaning hero)
• Bleach (handle with care and ventilation)
• Spray bottle
• Dish soap (mild but effective)

Step 1: Prep and Initial Inspection

Don your gloves and open the washing machine door.

Grab a dry cloth or paper towel and wipe out any visible lint, hair, or dirt from the seal folds. These little critters trap moisture and mould spores, so clearing them out is your first line of defense.

Give the seal a close look—mould loves sneaky spots inside the folds and crevices. The deeper it hides, the harder it is to evict. Remember: mould spores are not just on the surface, so thoroughness is key.

Step 2: Gentle Cleaning for Light Mould

If your seal shows just a few spots or mildew whispers, warm water mixed with a drop of dish soap can do the trick. Dip your soft toothbrush or cloth in the soapy water and scrub all the nooks and crannies of the seal. Rinse the cloth, wipe off soap suds, and you’re off to a fresh start.

Step 3: Bring In The Heavy Artillery — Tackling Stubborn Black Mould

Some mould just doesn’t quit after the gentle approach, am I right? Time to get a little tougher, but safely:

• Bleach-based mould cleaner: Lightly spray onto a microfibre cloth (not directly on the seal to avoid damage). Scrub the mouldy spots, then rinse the seal with a wet cloth. Pro tip: Always keep your laundry area well ventilated when using bleach and wear gloves to protect your skin. Source.
• Baking soda and bleach paste: Make a paste with equal parts baking soda and bleach to gently slap on those stubborn mould patches. Let it rest for 10 minutes before scrubbing with that trusty toothbrush. This combo earns extra points for effectiveness but demands respect for the chemicals involved.
• Vinegar alternative: Prefer to keep it mellow? White vinegar is an ace gentler option. Spray the seal with vinegar, let it sit for 15 minutes, then scrub. It’s great for moderate mould but might not conquer the fiercest infestations.
• Extreme cases — pool shock (calcium hypochlorite): This is the nuclear option for stubborn mould, found in some niche cleaning hacks. Handle with utmost caution, wear protective gear, and test a tiny spot first to avoid rubber damage. Video guide here.

Step 4: Rinse and Sanitize Like a Pro

After banishing the mould from the seal, wipe down with a clean damp cloth to remove any leftover chemical residue. Now, let’s sanitize the whole machine:

• Run an empty hot wash cycle, preferably at 90°C, to kill lingering spores.
• Add a cup of white vinegar to the detergent drawer for an extra clean boost. Vinegar’s natural acids help break down residue and deodorize.
• Once done, leave the door open to air dry thoroughly and keep moisture at bay.

Step 5: Maintain Your Mould-Free Machine

Preventing mould’s triumphant return is easier than fighting it once it’s entrenched. Keep these in mind:

• Clean the seal and detergent drawer monthly with appropriate cleaners.
• Always wipe the seal dry after each use, and leave the door slightly ajar between washes to let moisture escape.
• Use the right amount of detergent; excess soap builds up and invites mould.

What About Persistent Stains and Rubber Damage?

Here’s the hard truth: sometimes, mould leaves behind permanent black stains because it seeps into the rubber. Cleaning kills the mould and stops odours, but the ghost of stains past may linger. Additionally, excessive or harsh chemical use can degrade the rubber seal over time, so moderation and thorough rinsing is the name of the game.
