Overview
- Which? urges households to open windows or vents and spray equal parts water and white vinegar with a few drops of washing-up liquid on panes to reduce droplet formation.
- Additional steps include using extractor fans, putting lids on pans, drying bathroom surfaces, keeping heating low and steady, and considering a dehumidifier to cut indoor humidity.
- Homeowners are advised to inspect window seals and check double‑glazing warranties because failed seals can allow moisture between panes and may require repair or replacement.
- A Daily Mirror account describes placing a 65p bowl of table salt on the windowsill to absorb moisture and lessen morning condensation, noting results are anecdotal and the salt needs regular replacing.
- A separate Mirror test reported that wiping a thin film of washing‑up liquid on clean glass kept panes clearer for around two weeks, with salt performing weakly and bicarbonate showing partial improvement.
