How to Properly De-Ice Your Car

9th December 2019 | ifa_admin

It’s getting to that time of year again when car owners wake up to a frozen windscreen. It may seem like a simple problem to fix, but a surprisingly large number of people share bad advice when it comes to properly de-icing your windscreen.

Not only is it very dangerous to drive with a frozen, or part-frozen, windscreen, it can also land you with a fine and three points on your license. So, what IS the correct way to do it?

Use a solution – As most people know, a de-icing solution is easily purchased. But you could also make your own, buy mixing two parts rubbing alcohol with one part water. As a preventative, you could use a mixture of water and vinegar, which should stop ice forming the night before. Some people also recommend soaking a towel in a saltwater solution and leaving it on your windscreen overnight for the same result

Use an ice scraper – Simple, but often very effective!

Start your engine – defrost settings in your car, and the engine warmth will generally thaw your windscreen in about 10 minutes or so. A word of warning – ensure you stay inside your vehicle the entire time, or you could risk a £20 fine and 3 points on your license for idling your engine.


And a couple of things to avoid:

  • Don’t use anything other than an ice scraper on your windscreen, as you risk scratching it.
  • Don’t use boiling water. The shock of it on the cold glass could cause a crack.
  • Don’t try and rush it. Give yourself a little extra time in the morning, and remember how dangerous, and illegal, driving with limited vision is.
