Several outlets report that mould can build up in washing machines when damp areas—such as the drum, door seal and detergent drawer—are left to remain wet after cycles. Both sources recommend a quick habit after each wash to reduce the conditions that allow mould to grow. The guidance focuses on taking a brief action once the programme finishes, typically involving ensuring the machine is left in a way that allows moisture to dissipate and surfaces to dry more quickly. The advice is presented as fast—taking only a few seconds—and is aimed at interrupting the mould-growth cycle by limiting lingering dampness. While the reports frame the method as a preventive “quick task” rather than a full deep clean, they emphasize that consistent after-wash attention can help keep machines cleaner over time. The articles do not detail specific chemical treatments or replacement parts, instead stressing that a small routine performed after every wash can make it less likely for mould to take hold.
