As UK temperatures climb, washing machines become breeding grounds for mould. Fungal spores thrive in humid conditions, and after a wash cycle, the drum and detergent drawer stay damp, accelerating mould growth. Mould creates slimy residue, causes blockages, and leaves clothes smelling musty.
Simple prevention method
Marilee Nelson from cleaning brand Branch Basics says the best way to prevent mould is to leave the washing machine door ajar after each wash. She explains: "Mould and mildew cannot grow in your front loader without a food and water source. So, your first step is to remove the moisture from your washer by leaving the door open between washes."
This simple step allows air to circulate, evaporating moisture. Leaving the door and detergent drawer open after removing clothes keeps surfaces dry and prevents mould.
How to deep clean a mouldy machine
If slimy residue or musty odours appear, use distilled white vinegar. Spray it on the detergent drawer and inside the rubber door seal—areas where soap and moisture trap easily. Leave for five minutes, then wipe with a damp cloth. For a thorough clean, pour white vinegar into the drawer and run a hot empty cycle to flush out spores.
Regularly leaving the door open and using white vinegar keeps the machine spotless during summer.
