Brits are raving about an unusual hack to banish condensation from windows – for just 69p.

As the UK braces for the coldest snap of the year, many people will have woken up to the familiar dreaded sight of icy rooftops and soaking windows.

Condensation forms on the inside of windows when warm air from indoors collides with cool glass. It is more common on colder days, because turning up the central heating to combat chilly weather creates a bigger difference between indoor and outdoor temperatures.

If left unchecked, the excess moisture can lead to mould, which in turn poses serious health risks like respiratory problems and allergic reactions. In fact, condensation is often the main culprit behind mould in our homes, particularly when temperatures drop.

To put an end to the daily stress of wiping sodden windows dry, cleaning gurus recommend reaching for a popular household product that can be found in many bathrooms, or purchased from Aldi for just 69p.

It turns out that shaving foam can be used as an effective – and cheap – hack to manage the nuisance droplets on your windows.

Apply a small amount of shaving foam to a dry microfibre cloth then wipe it across your windows, buffing it in evenly. Next, use a squeegee to remove any excess product.

A thin, transparent film of foam will cling to the panes of glass and banish condensation. When moisture in the air tries to condense on your windows, the detergent in the shaving foam prevents the water from beading to stop the mist from forming.

According to the RAC, the trusty hack has been used by drivers to defog their windscreens for years. Before that, it was even adopted by ice-hockey players, who used shaving foam to prevent their visor from misting up.

Experts warn that the shaving foam will need reapplying every few weeks to ensure that there is a consistent level of product to prevent condensation from reappearing.

The unusual strategy has wowed frustrated individuals who face a daily battle with condensation. Sharing their tips and feedback on a cleaning forum, one user wrote: “It works! I do this each week to keep on top of it”.

Another enthusiast gushed: “Living in a Ski️ Resort, this gem is a life saver for our wild winters!”, while a further added: “Tried this and I can’t believe it actually works – does make you wonder what men are putting on their face though…”
