A simple 55p kitchen staple could be the answer to window condensation and mould, offering a budget-friendly alternative to expensive dehumidifiers. Homeowners have discovered that washing-up liquid, when applied to windows, can prevent moisture build-up overnight.
The hack involves pouring a small amount of washing-up liquid onto a dry cloth or sponge and wiping it over the window until covered. The liquid is left to dry naturally without being wiped off. One user reported that the next morning, there was no condensation or 'mass of water droplets' compared to previous nights.
Budget brands such as Asda's Essential and Morrison's own brand cost just 55p, while Sainsbury's own brand is 62p and Aldi and Tesco's own brands are 69p. Many households may already have a bottle under the sink, making it an even more cost-effective solution.
While this hack offers a quick fix, experts note that dehumidifiers remain effective for reducing overall humidity and mould. However, they caution that choosing the wrong size or placing the unit incorrectly can reduce efficiency. A dehumidifier should be placed in the centre of a room for optimal airflow.
For those looking to save money, the washing-up liquid method provides an immediate, low-cost alternative to combat condensation and mould without the need for electrical appliances.
