Washing-up liquid applied to windows can prevent condensation and the mould it causes, according to specialists at Horizon Windows, offering a low-cost alternative to daily wiping.
How the washing-up liquid trick works
Horizon Windows said: "A tiny amount of washing-up liquid rubbed onto your windows with a dry cloth can work wonders at preventing condensation. It creates a barrier that helps repel water droplets."
The liquid contains surfactants that stop water droplets from forming on a surface. It leaves a thin film on the glass, causing condensation to spread out into a fine layer before evaporating quickly.
Applying the solution to window panes
To use the method, squeeze a small amount of washing-up liquid into a bowl of hot water. When diluted, it will not leave marks or streaks on the glass.
Dip a cloth into the soapy water and spread it evenly across the window pane, covering the entire surface uniformly so the liquid forms a thin layer over the glass. Gently buff the window with a dry cloth to soak up excess water, leaving the washing-up liquid coating on the glass.
Reapplying to keep mould at bay
The solution should be reapplied every two to three weeks to prevent condensation from building up. This keeps windows dry and free of condensation, helping to stop mould from taking hold in the home during winter.
