Overview
- An Instagram cleaning influencer urges a 10‑minute daily window‑opening routine to flush moisture and target 40–60% indoor humidity, claiming it reduces condensation and mould risk.
- Consumer body Which? recommends spraying windows with equal parts water and white vinegar plus a few drops of washing‑up liquid to create a protective barrier, alongside steady low heating, dehumidifiers at night, and checking window seals.
- Kitchen‑fitting expert Simon Roberts, echoing multiple UK councils, advises running cold water first when filling sinks, pans or baths before adding hot to cut steam—and thus condensation—by up to 90%.
- Social‑media users promote inexpensive moisture absorbers such as cat litter stuffed into socks for windowsills, with reported costs as low as about £2.19 and informal advice to replace monthly.
- Other low‑cost tips include placing bowls of table salt on windowsills or behind curtains to draw moisture, with experts noting it should be refreshed once it clumps from saturation.
