How to Deal with Fogging on Car Windows?
1 Answers
Use anti-fog spray: Apply a small amount of defogging agent on the car glass and then wipe it dry. Utilize air convection: Due to seasonal temperature differences between the inside and outside of the car, warm and humid air inside the car meets the cold windshield and then reheats, leading to easy condensation and fog formation. Use the warm air from the air conditioner: Turn on the warm air and direct it toward the glass to quickly heat up the front windshield. Fog: When the relative humidity in the air reaches 100%, water molecules in the air condense into particles suspended in the air. Water droplets refract light, similar to high-density suspended particles in the air, causing natural light to reflect at countless angles. Fog acts as a natural light barrier, obstructing visibility due to the infinite refraction of light by water droplets—this is why visibility is low in foggy conditions. Recommended Methods: In winter, use the "front windshield/footwell" vents while driving. Warm air is less dense than cold air inside the car, so the cold air blown in will rise. Thus, directing airflow from the footwell can make the whole body feel warm. Keeping one vent blowing on the windshield ensures continuous heating—cooling from the outside and heating from the inside prevent the windshield from becoming too cold and fogging up, while warm air also helps dry any gradually condensing moisture. In summer, avoid using the "front windshield/footwell" vents to prevent the windows from becoming too cold.
