Households are finding simple ways to handle changing weather patterns indoors as autumn approaches. A quick kitchen trick is gaining attention as temperatures drop across the country.

As autumn weather creeps into homes across the country, many people are bracing for the familiar drop in temperature.

Chilly mornings often bring a frustrating side effect inside, with droplets covering cold glass panes.

Dealing with damp indoor air is a battle most households know all too well, writes the Daily Express Yet the solution to this seasonal headache might already be sitting right next to your kitchen sink.

Smart soapy trick

Households are being urged to rub ordinary washing up liquid onto their windows this autumn to stop condensation in its tracks. As cooler and wetter weather takes over, warm air inside homes clashes with cold glass surfaces. This creates a layer of fog and dripping water that can quickly turn into damaging black mould.

A quick wipe with dish soap offers a surprisingly cheap fix. According to the newspaper, washing up liquid contains surfactants that lower the surface tension of water. Instead of forming heavy droplets, the moisture spreads out into an invisible layer that simply evaporates away.

Cleaning brand Home Things explained the technique in its online guidance for tackling wet windows:

“By taking a small drop of washing up liquid and rubbing it into the condensation-prone window with a dry cloth, you can completely stop the issue altogether.”

The brand added that “the washing-up liquid forms a barrier on the surface of the windows, preventing the water from sticking. So in the space of just a few minutes, you can put a stop to the damp, mould, and mildew that wet windows can cause.”

Quick temporary fix

While the hack costs under a pound, experts warn that it is not a permanent cure. Specialists at Glazing Refurbishment points out that the soap film gradually wears away over time and requires regular reapplication.

“Applying a small amount of washing-up liquid to your windows can temporarily prevent condensation from forming,” the specialists explained. “It works by creating a thin film that lowers surface tension and prevents water droplets from forming on a cold surface.”

They noted that “it’s best applied to the bottom of the windows where condensation tends to accumulate the most,” while adding that long-term control still requires proper home ventilation and insulation.
