Households are being warned they may be unknowingly creating the perfect conditions for mould to thrive in their washing machines. Gwilym Snook, a laundry specialist at AO, has identified a simple yet widespread error that promotes mould growth: closing the door immediately after a wash.
According to Snook, this common habit traps moisture inside the drum, allowing mould and bacteria to flourish in the rubber seal and detergent drawer. To combat this, he advises always leaving the machine door ajar after a cycle to let it air out.
Snook also shared a budget-friendly 50p hack using white vinegar to tackle early-stage mould on the seal. 'White vinegar is a natural wonder for breaking down the soap scum and lint that mould feeds on,' he explained. 'I recommend wedging vinegar-soaked cotton pads into the rubber and leaving them for around two hours, then wiping clean with a damp microfibre cloth.'
For stubborn stains, a diluted bleach solution may be needed, followed by a high-temperature maintenance wash. Snook emphasised that regular cleaning of the door seal, drawer, and filter is essential to prevent mould and keep laundry smelling fresh.
Other tips include avoiding overfilling the drum, not leaving wet clothes sitting inside, and running a hot empty cycle periodically to clear hidden residue. 'Detergent alone won't keep a washing machine clean,' Snook said, noting that these simple habits can make a noticeable difference over time.
