How to Deal with Foggy Windshield on Rainy Summer Days?

[DiGiselle]

Here are the solutions for dealing with a foggy windshield on rainy summer days: 1. Lower the windows: Roll down the windows slightly to create a gap, reducing the temperature difference between the inside and outside of the car, which will make the fog disappear. In summer, fog forms on the outside of the windshield. The temperature inside the car is lower, while the outside temperature is higher. When the hot outside air meets the cold glass, the water vapor in the outside air condenses into tiny droplets on the cold glass. 2. Turn on the air conditioning: After turning on the air conditioning, use the recirculation mode and adjust the air vents to blow towards the windshield, which will quickly clear the fog inside the car. 3. Turn on the heater: Adjust the switch to the heating position, increase the fan speed, and also set the air vents to blow towards the windshield. This will raise the temperature inside the car and dry the air.
