What to Do When Car Air Conditioning Causes Water Droplets on the Windshield?

[Long]

You can use a long-lasting car anti-fog and anti-rain spray. Here are the relevant details: 1. Function of anti-fog and anti-rain spray: It forms an anti-fog film on the windshield and rearview mirrors, effectively preventing fog formation. 2. Principle: When moist air inside the car comes into contact with the cooler windshield, the water vapor in the air condenses due to the temperature difference, gradually forming droplets that eventually gather into fog on the glass. Therefore, as long as there is a significant temperature difference between the inside and outside of the car, or if the humidity inside the car is too high, fogging will occur.
