4 Settings To Defrost Your Windows Faster

January 8th, 2016 by

When you find your pre-owned BMW’s windshield covered in a layer of fog or frost, what is the best way to defog it? Using the window defroster for your car is key, but there are other steps you can take when wondering how to defrost car windows fast. Should you open your windows, or keep them sealed? Is hot air, or cold air better?

Former NASA engineer Mark Rober tested all the variables over ten days of controlled trials to come up with the best combination of defroster settings.

  • First, turn the front defogger on high. If your vehicle has a rear windshield defroster, turn that on as well.
  • Turn the fan on high. This maximizes the amount of drying air.
  • Turn the temperature on high. Warmer air holds more moisture and can dry the fog faster.
  • Turn the air conditioning on. This makes the fan act as a dehumidifier.
  • Turn off recirculated air. Outside air is dryer than your humid car on a cold day.

These settings should cut down the time you have to wait until your windows are clear. Remember not to drive when your windshield is frosted over, or you might just end up needing our collision repair center.
