How to Defog When Driving in Rainy Summer Days?

[DeRowan]

The usual method is to turn on the car's fan and cooling switch, so that the cold air blows onto the glass, quickly dispersing the fog with fast and direct results. Here are more methods for defogging: 1. Use specialized defogging products. Many markets and auto parts stores have stalls selling dedicated defogging and anti-fog products, such as defogging sprays or fog towels. Spray this type of defogging agent onto the inner surface of the car glass and wipe it clean. While removing dirt from the glass, it also forms a thin transparent protective film that prevents water vapor from condensing into fog on the glass. One application can prevent fog for about ten days to half a month. 2. Open windows for convection: If the fog is not heavy, you can open a small gap in the side windows to allow air convection inside the car. The temperature inside the car will gradually approach the outside temperature, and the fog will disperse. 3. Detergent-based anti-fogging: Mix dishwashing liquid with water in a ratio of about 1:10, then use absorbent cotton or a clean, soft cloth to apply it to the inside of the front and rear windshields.
