Stop condensation on windows by placing 59p item nearby - not dehumidifier

Condensation on windows is a common winter problem, but one low-cost approach circulating online suggests using bicarbonate of soda rather than a dehumidifier. The advice targets moisture that forms when colder temperatures and indoor heating cause water vapour to collect on cold glass, leading to misted panes, damp sills and potential mould and odours. The method is to place bicarbonate of soda in a small bowl near affected windows, loosely cover it with a lightweight cloth to prevent spills, and replace it when it clumps as it absorbs humidity. The article cautions it works best in smaller areas, where cooking steam, showers or drying laundry indoors may overwhelm the effect.
