The hidden ecosystem in your laundry: Why your washing machine might be making your clothes smelly

Your washing machine, surprisingly, is a breeding ground for odour-causing microbes. Modern cold washes allow bacteria and oils to accumulate, forming resilient biofilms that cling to clothes. These biofilms metabolise residues, releasing unpleasant smells. To combat this 'permastink' and prevent cross-contamination, a monthly hot wash with bleach is recommended, along with leaving the door ajar.
