Your front window can fog up very quickly and manufacturers often offer a feature where if you press the button that looks like this, it turns the air conditioning on, directs all air to the windscreen and turns the fan up full. This will clear the windscreen as quickly as possible.
A defogger, demister, or defroster is a system to clear condensation and thaw frost from the windshield, backglass, or side windows of a motor vehicle. The rear window defroster was invented by German automobile engineer Heinz Kunert.
Do you use hot or cold air to Demist car?
Use the air-con in conjunction with the heater. Hot air will dry the glass a little through evaporation, but the air will then cool down and condense on the glass once more, so make sure the air-con is on to keep the atmosphere inside dry. If your windscreen is iced over, then the heat is obviously more necessary.
Hit the car windscreen demister button without air-conditioning and the ventilation system will try to warm up the windscreen, by blowing warm air at it and/or by running an electric current through a thin wire stuck onto the screen (more common in rear windscreens) to warm up the wire, and eventually, the window.
