Can you tell me how to stop the inside of a car from fogging?

On very cold mornings, my car windows are covered in condensation, making it hard to see out. How do you stop the inside of a car's windows from fogging?

That definitely makes it hard to see! There are, however, a few solutions to de-fog your car windows on a cold morning.
  • Turn on the air conditioner. The AC will remove moisture from the inside of the vehicle. You can turn the temperature to around 70 degrees, so you don’t get too chilly, and make sure cabin recirculation is off.
  • Use the heater. The heater can fight fog by heating up the windows, so water doesn’t condense. If you notice your breath is causing more fog, roll the windows down.
  • Fill a sock with cat litter. Since litter absorbs moisture, it will help reduce condensation in your car.
To prevent windows from fogging up in the future, make sure you
keep them clean
, since dirt can attract moisture.
Now that you’ve got your foggy windows under control, consider adding a roadside assistance membership for any other issues.
