How to Solve Fogging on the Outside of Car Windows in Summer Rain?

[PhoebeFitz]

When car windows fog up during summer rain, if the fogging is slight, wiping with a towel will suffice; if the fogging reappears after wiping, you can adjust the temperature difference between the inside and outside using the air conditioning and wait for the fog to disappear. Turning on the air conditioning can quickly remove the fog inside the car. After turning on the air conditioning, use the recirculation mode and direct the air vents toward the windows. The fog inside the car will clear up immediately, with very fast results. However, there is a drawback: the temperature inside the car will also drop, which can be uncomfortable in winter. Additionally, using the warm air from the air conditioning can also clear fog on the windows. Adjust the switch to the warm air position and set the fan speed as high as possible, also directing the air vents toward the windows. This will raise the temperature inside the car, dry the air, and prevent fog from forming on the windows. However, this method is not suitable right after starting the car; you need to wait for the engine to warm up for it to be effective.
