The 12c hack for preventing windscreen frost thanks to kitchen staple

With UK temperatures dropping to -2 degrees in some places today and more cold weather on the way, it means it’s going to get frosty out there. Sub-zero temperatures means icy car windscreens, which can be extremely annoying in the early hours of the morning when you need to set off to work.

Frosty windscreens aren’t just an annoyance, but can actually land drivers with a £100 fine and three points on their licence. Luckily, cold weather experts from Iceland, Lotus Car Rental, have revealed an incredibly clever and bizarre hack that should keep your windscreen from freezing over using a staple item from your kitchen.

The item in question, which costs about 12p from most supermarkets, is an onion.

According to the experts, onions can break down frost as soon as it forms on the window.

Simply cut an onion in half and rub it generously all over the windows and windscreen the night before you need to drive. This should stop frost from forming in the first place.

If you don’t have an onion, a potato should work in the same way – and at least it won’t make you cry in the process.

Vinegar works in the same way, so you could spray a vinegar solution mixed with water on your windscreen the night before.

The experts explain that vinegar is often “used as a de-icer because its freezing point is much lower than water’s, meaning the water doesn’t have the chance to settle and freeze on top of the vinegar”.
