Mould in your washing machine is one of those sneaky little monsters. Just because you don’t see visible black spots doesn’t mean mould spores aren’t lurking in the rubber seal or other hidden areas.
Unfortunately, no product can truly guarantee it "kills 100%" of mould—precisely because these pesky spores often hide where you can’t see them. That's why prevention matters more than trying to eliminate every last microscopic squatter.
Why Mould Grows in Machines: A Spore’s Paradise
Mould thrives in warm, damp, and dark environments. Sound familiar? That’s the perfect description of the inside of your washing machine drum, especially those front-loaders.
Residual water left after a cycle, paired with detergent and fabric softener residue, gives these spores everything they need to settle in and start a family. Add to that a sealed door or detergent drawer, and moisture becomes trapped, essentially creating a luxury spa for mould growth.
Prevention Is Your Best Friend
Leave the Door Open After Every Wash
Once your cycle finishes, swing that machine door slightly ajar. This lets air circulate and helps the drum dry. It's the simplest—and frankly, the most recommended—way to stop mould from setting up shop.
Let the Detergent Drawer Dry
That little drawer is a residue magnet. Dampness encourages a slimy buildup. Give it a break and leave it open after each wash to allow it to dry out fully.
Wipe Down Seals and Gaskets Regularly
The rubber seal around front-loader doors traps moisture, lint, and soap scum. After each wash, give it a quick wipe with a dry cloth. And do a more thorough clean weekly using a mild solution (like water and vinegar) to evict any unwanted residents before they get comfortable.
Use the Right Amount of Detergent
Stop free-pouring! Using too much detergent (or softener) can leave a sticky film inside the machine. That residue doesn’t just affect your laundry—it serves as an all-you-can-eat buffet for mould. Stick strictly to the manufacturer’s recommendations.
Run a Monthly Maintenance Cycle
Running an empty hot cycle once a month with white vinegar is like hitting the reset button—it helps eliminate buildup and keeps the drum fresh and clean.
Improve Ventilation in Your Laundry Room
If your laundry room feels damp, it’s time to intervene. Consider using an exhaust fan or dehumidifier. Reducing the overall humidity helps prevent mould not just in your washing machine but across your whole space.
Expert tip: You can’t see every single spore, so don’t expect a silver-bullet mould killer product to save the day. Instead, focus on preventing growth by keeping your machine dry, ventilated, and residue-free. Small habits—leaving the door ajar, wiping down seals, and running a cleaning cycle—will save you from a major mould headache down the track.
