YouTuber Mark Rober used science to determine the most effective way to defog your car.

He notes: “Some cars have a single button to defrost all windows, but many cars have controls that look like this.

“A lot of people just blow the windshield with hot air. But what if you use cold air?

“And should you use forced air or outside air? And pressing the air conditioner button or opening the window helps speed things up? And if so, by how much?”

Mark explains that after a series of tests to get rid of the frost in his car he found the quickest and best way to do it.

There are four simple steps you need to follow to get guaranteed results.

He said: “Number one, turn the heating up to full blast. This is because, as I said, hot air can hold more moisture.”

Mark continues with step number two which is to turn on your air conditioner as this will help absorb any moisture that is still in the air.

He said: “Number three: make sure the airflow inside is turned off. The winter air is cold and we know it doesn’t hold much moisture. So if you put it in your car and heat it up, it has a great absorption capacity.

“Finally, number four: open your windows only briefly. It may not be possible when it’s freezing cold outside or it’s raining, but it helps to open as many windows as possible for even a few seconds by first exchanging the humid air inside your car with the dry air outside. “

Mark concluded that results may vary depending on weather conditions and the type of car you have, but in general these four steps seem to do the trick.
