How to quickly and safely remove frost from your windshield

KNOXVILLE, Tenn (WATE) – Now that cold weather has returned and many of us have to take time to remove frost from our car windshields early in the mornings.

It was another cold morning Tuesday with most areas waking up to temperatures in the teens and 20s. If you left your car outside, it probably had scattered frost on the windshield.

There are two ways to get rid of this. First, you can warm up the car for a long period of time, turn the defroster on and that will get rid of the frost. However, this a waste of gas. The other way is by using a good old ice scraper. It takes time, but it will eventually do it.

Here’s a better way: a simple solution where all you do is spray and the frost is gone. The mix does not include hot water. You can’t add hot water to a cold windshield, because it can break it. It is just a simple spray of solution on the windshield will make that de-icing a lot easier.

The solution is is actually very simple and most of you probably already have this in your home – isopropyl or rubbing alcohol that you mix with water.

You take one-third part water and mix it with two-thirds parts of isopropyl or rubbing alcohol. You mix these solutions together and pour it into a simple spray bottle.

The reason why this works is rubbing alcohol has a freezing point of 128 degrees below zero. So, you can always keep this mixture in your car and it will never freeze. provides commenting to allow for constructive discussion on the stories we cover.
