How To Clean Mould Out Of Washing Machine

Ah, the humble washing machine. Our trusty sidekick in the never-ending battle against laundry day grime. It's the unsung hero of clean socks and fresh-smelling towels. But what happens when this domestic goddess herself starts to look a little… well, a little green? Yep, we're talking about mould. That fuzzy, often musty invader that can turn your sparkling clean wash into a damp, mildewy disappointment. Don't despair, though! Tackling washing machine mould is less of an epic quest and more of a chill weekend project. Let's dive in, shall we?
Think of mould like that one acquaintance who overstays their welcome at parties. Annoying, a bit smelly, and definitely not invited. In our washing machines, it thrives in the damp, dark corners, feasting on leftover detergent residue, fabric softener, and – you guessed it – all those tiny bits of fluff and lint that escape the drum. It’s especially fond of the rubber seal around the door, that little gasket that’s so crucial for keeping your clothes dry and your machine happy.
Now, before you start imagining your washing machine morphing into a science experiment gone wrong, let’s get down to brass tacks. Cleaning mould out of your washing machine is not only doable, it’s actually pretty straightforward. And hey, it’s a great excuse to get a little domestic goddess energy flowing. Channel your inner Marie Kondo, but instead of sparking joy, we’re sparking clean!
Why Does Mould Even Show Up?
It’s all about the environment, darling. Washing machines, by their very nature, are damp places. We fill them with water, add soap, and then leave them to sit between cycles. This constant moisture, combined with residual detergent and fabric softener that doesn't always get fully rinsed away, creates the perfect breeding ground for mould and mildew. Think of it like a tiny, humid jungle, and mould is the king of the jungle, reigning supreme in the dark, steamy confines of your machine.
Low temperatures are also a culprit. If you’re a fan of those cooler washes (which are great for saving energy, by the way!), they might not be hot enough to kill off mould spores. And let's be honest, who always leaves the washing machine door open after a cycle? If your machine is tucked away in a humid laundry room, that lack of ventilation further helps mould to set up shop.
The type of detergent you use can also play a role. Liquid detergents, while convenient, can sometimes leave behind residues that mould loves. Powdered detergents tend to dissolve more completely. It’s not about ditching your favourite brand, but being aware that residue is a mould party invitation.
The Mould-Busting Arsenal: What You'll Need
Don't worry, you don't need a hazmat suit or a degree in chemistry. Most of what you need is probably already lurking in your cleaning cupboard. We're talking about your everyday heroes:

- White vinegar: The undisputed champion of natural cleaning. It’s acidic, meaning it can break down mould and kill those pesky spores. Plus, it smells way better than bleach (in my humble opinion!).
- Baking soda: Another fantastic all-rounder. It's a mild abrasive, great for scrubbing, and it also helps to deodorise.
- Microfibre cloths or old rags: For wiping and scrubbing. Microfibres are great because they trap dirt and mould effectively.
- An old toothbrush or a small cleaning brush: Perfect for getting into those nooks and crannies where mould likes to hide.
- A spray bottle: For easy application of your cleaning solutions.
- Rubber gloves: To protect your hands, especially if you have sensitive skin.
- Optional: A mild dish soap: For a bit of extra oomph in stubborn areas.
And of course, a positive attitude. Think of it as a mini spa day for your washing machine. She deserves it!
Operation: De-Mould Your Machine
Alright, let’s get to the good stuff. We’re going to tackle this in a few easy steps, focusing on the main mould hotspots.
Step 1: The Door Seal – The Grand Central Station of Mould
This is where the majority of the trouble usually starts. That rubber gasket around the door is a magnet for moisture and debris. First, grab your trusty spray bottle and fill it with a 50/50 solution of white vinegar and water. If you’re feeling brave, or the mould is particularly stubborn, you can use undiluted vinegar. Give the entire seal a good spray.
Now, let it sit for about 10-15 minutes. This gives the vinegar time to work its magic and start breaking down the mould. While it’s marinating, you can admire your sparkly clean kitchen counters or catch up on your favourite podcast. Multitasking, right?
After the waiting period, take your microfibre cloth or an old rag and thoroughly wipe down the seal. You’ll want to get into all the folds and crevices. This is where that old toothbrush comes in handy! Use it to scrub away any lingering mould or discolouration. For really tough spots, you can make a paste of baking soda and water. Apply it to the mouldy areas, let it sit for a few minutes, and then scrub gently with your toothbrush or cloth.

Don't forget to wipe away any excess moisture and residue afterwards. You might need to rinse your cloth a few times. The goal is to leave that seal looking pristine and smelling fresh.
Step 2: The Detergent Drawer – A Forgotten Frontier
This little compartment can get seriously gunky. Mould loves the sticky residue left behind by detergents and fabric softeners. If your drawer is removable, take it out completely. This makes cleaning so much easier. Give it a good soak in warm, soapy water (a little dish soap is good here) and then scrub it clean with your trusty toothbrush or a small brush. Rinse it thoroughly and dry it before popping it back in.
If the drawer isn't removable, or if you just want to give it a quick clean, spray it generously with your vinegar solution. Let it sit for a few minutes, then scrub with your toothbrush or a cloth. Make sure to get into all the little compartments where the detergent and softener go.
A fun fact: In some cultures, like ancient Rome, they used urine as a cleaning agent! Thankfully, we’ve moved on to much nicer-smelling (and more effective!) solutions. So, be grateful for your vinegar and baking soda!
Step 3: The Drum – The Heart of the Matter
Now, for the main event. We're going to give your washing machine drum a deep clean. The best way to do this is with a hot wash cycle, and we’ll be using vinegar and baking soda to really get in there.

First, pour about two cups of white vinegar directly into the detergent drawer. This ensures it gets washed through the machine during the cycle. Then, sprinkle about half a cup of baking soda directly into the empty drum. This might seem a bit odd, but the baking soda will help to scrub away any remaining residue and neutralise odours.
Once your vinegar and baking soda are in place, run your washing machine on its hottest and longest cycle available. A 'hot wash' or 'sanitize' cycle is ideal if your machine has one. This high heat is crucial for killing off any lingering mould spores and bacteria.
While the machine is rumbling away, you can finally relax. Put your feet up, enjoy a cuppa, or perhaps do a quick five-minute meditation. You’re already halfway to a cleaner machine!
Step 4: The Exterior and Beyond
While you’re on a cleaning roll, don’t forget the outside! Wipe down the exterior of your washing machine with a damp cloth and a bit of all-purpose cleaner. Pay attention to the control panel and the handle. Sometimes, mould can even creep onto the outside if there’s been a particularly damp laundry room environment.
And what about the filter? Most washing machines have a small filter, usually located at the bottom front of the machine. This traps lint, coins, and other small items. If it's clogged, it can contribute to mould growth. Check your machine’s manual to find out how to access and clean your filter. It’s usually a simple case of unscrewing a cover, being prepared for a little bit of water to escape (have a towel and a shallow dish ready!), and pulling out the gunk. Give it a rinse and pop it back in.

Preventing Future Mould Invasions
Cleaning is great, but prevention is even better! Nobody wants to be constantly battling mould. Here are some simple habits to keep your washing machine fresh and mould-free:
- Leave the door open: This is probably the single most effective tip. After each wash, leave the washing machine door slightly ajar. This allows air to circulate and the drum to dry out, making it a less hospitable environment for mould.
- Wipe down the seal: A quick wipe of the rubber door seal with a dry cloth after each use can make a big difference. Just a few seconds to remove excess moisture.
- Remove wet clothes promptly: Don’t let damp clothes sit in the machine for ages. Transfer them to the dryer or hang them up as soon as the cycle is finished.
- Use the right amount of detergent: Overusing detergent can lead to residue buildup, which mould loves. Follow the manufacturer’s instructions.
- Run a hot wash occasionally: Aim to run a hot wash cycle (above 60°C or 140°F) at least once a month, even if you usually wash at lower temperatures. This helps to kill off any sneaky spores.
- Clean the detergent drawer regularly: Give it a quick wipe down or rinse every few weeks.
- Consider a washing machine cleaner: There are specific washing machine cleaning products available that you can use periodically.
Think of these as small, mindful practices that contribute to a healthier home. It’s like a tiny act of self-care for your appliances!
