Which button to press when there is fog in the car?

[HarleyRose]

Press the front window defogger button when there is fog inside the car. When the temperature inside the car is higher than the outside temperature, fog forms. Here are some methods to remove fog: 1. Special defogging products: Spray this type of defogging agent on the inner surface of the car glass and wipe it clean. It not only removes dirt from the glass but also forms a transparent protective film on the glass, preventing water vapor from condensing and forming a fog layer. 2. Open windows for air circulation: If the fog is not heavy, you can open a gap in the windows on both sides (do not do this when it is raining). This allows air inside the car to circulate, and the temperature inside the car will gradually approach the outside temperature, causing the fog to dissipate.
