Overview
- Allan Reid of Art Windows and Doors advises placing a small bowl of table salt or silica gel on the windowsill before bed in rooms prone to fogging.
- Wipe existing moisture first, then briefly open windows in the morning to release trapped damp air and refresh the room.
- Replace the salt or silica gel once it turns clumpy, keep trickle vents open, check and reseal older windows, and pull furniture slightly away from exterior walls to improve airflow.
- The guidance cites the basic cause of condensation as warm, moist indoor air meeting a colder glass surface during colder weather.
- An alternative tip previously shared by cleaning expert Lyndsey suggests rubbing a tiny drop of neat washing-up liquid over affected panes to keep them clear.
