How do I defog my car windows?

What’s the best way to defog my car windows when it rains? I feel like I always just turn on defrost, but sometimes it seems like it makes the problem worse.

There’s nothing worse than foggy windows! Luckily, there are a few things that you can do to defog your car windows when it rains:
  • Turn off air recirculation. If you use your defrost, turning off air recirculation can prevent excessive fogginess.
  • Turn on your AC. Your air conditioning system can help by absorbing excess moisture in the air. It’s a good idea to turn on your heat as well. The heat will take moisture out of the interior and the AC will help remove it from the air.
  • If it’s not raining too hard, open your windows to get some fresh air into your car.
  • Clean your windshield to improve visibility, then use a fog preventative like RainX to help prevent fogging in the future.
