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

He notes that: "Some cars have a single button to defrost all the windows but a lot of cars have controls that look like these.

"Lots of people just blast the windshield with hot air. But what if you use cold air?

"And should you be using recirculated air or air from outside? And pushing the A/C button or cracking the window helps speed things up? And if so, by how much?"

Mark explains that after performing a series of tests to get rid of the frost in his car, he has 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 heater on full blast. This is because as we said, hot air can hold more moisture."

Mark continues with step number two which is to turn your A/C on as it will help absorb the moisture that is still in the air.

He said: "Number three: make sure inside air circulation is off. Winter air is cold and we know it doesn't hold much moisture so if you bring it into your car and you heat it up, it has a lot of absorption capacity.

"Finally number four: crack your windows for just a little bit. It might not be possible if it's freezing cold or if it's raining outside but cracking as many windows as possible even for a few seconds helps by initially exchanging the humid air in your car with the dry air from outside."

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