Washing machine mould can be stopped with a three‑second post‑wash routine

Home‑appliance users are advised to spend a few seconds after each wash wiping the door seal and detergent drawer and leaving the door ajar. The quick task – about three seconds – is reported to prevent mould growth that can cause musty odors and degrade the rubber seal. Advice originated on the Mumsnet forum, where users shared the tip and recommended using a vinegar‑water solution for any existing mould, noting that vinegar penetrates porous material more effectively than bleach.

The guidance has been reproduced by multiple UK outlets, emphasizing that keeping the seal and drawer dry after each use can keep washing machines mould‑free for the long term.
