What to Do When the Front Windshield is Blurry on Rainy Days?

[McColin]

The methods to deal with a blurry front windshield on rainy days are: 1. Turn on the defogging mode; 2. Open the windows for air convection to balance the temperature inside and outside the car; 3. Spray defogger on the windshield; 4. Use the car's heating or cooling system to blow air onto the windshield. Precautions for driving on rainy days include: 1. Maintain a sufficient safe distance; 2. Use lights correctly; 3. Avoid harsh braking, sudden acceleration, or sharp steering. Windshield glass is produced by heating the glass in a furnace to near its softening temperature, then sending it through air grids with varying cooling intensities to unevenly cool the glass, creating different stresses between the main viewing area and the peripheral areas. This process produces zone-tempered glass.
