Why do we get foggy windows in the winter? It has to do with temperature and air moisture. When the air outside your vehicle differs greatly from the air in your vehicle, the fog will appear. This means that the winter air, which is cold and dry, is counteracted with any warm and humid air inside the vehicle. This can be brought on from anything like hot food, turning on the warm air, or melted snow on your boots.
So how do you get rid of the fog? Defog your windshield by balancing the air quality inside your vehicle with the air quality outside. Turn off recirculation by looking for the proper button, usually marked by an arrow inside a car icon. To speed up the process, you can turn on the heat at the maximum setting and then strip the air’s moisture by turning on the AC. If possible, crack the windows for a short period to exchange the airflow. To stay cozy and warm, you can also turn on the defroster and direct warm air across the windshield.
