This is the Fastest Way to Defog Your Windshield
This trick will save you time and keep you safer while driving this winter.
Windows can fog any time of the year, whether it’s summer or the middle of winter. But cold temperatures can create the ideal conditions for foggy windshields. You and your passengers warm up the cold air inside the vehicle. And when the warm moisture hits the cold glass, fog and condensation occurs.
How to Defog a Windshield With AC
Even if it’s freezing cold outside, turn on the AC and aim the vents up so the airflow hits the windshield. Your car’s air conditioning system also acts as a dehumidifier, so it will quickly remove the moisture inside the vehicle by circulating the air through the cold fins in the evaporator.
If your vehicle doesn’t have air conditioning, or it doesn’t work, turn the blower on high and open your windows a crack to allow moisture to escape.
Next time your windshield fogs up, crank up your car’s AC. Your windows will defog quickly and you’ll be on your way.
