What are the methods to prevent fogging on the car's front windshield?

Methods to prevent fogging on the car's front windshield include: 1. Turn on the front window defogging mode, increase the fan speed, turn on the temperature control, and lower the temperature; 2. Activate the one-touch defogging function; 3. Open the windows to increase air circulation, reduce the temperature difference between the inside and outside of the car, and weaken the conditions for fog formation; 4. Spray defogging agent evenly on the glass surface and wipe it clean with a dry towel; 5. Make a homemade defogging solution with dishwashing liquid and spray and wipe it before driving. The reasons for car windshield fogging are: 1. When the window temperature is below the dew point, condensation forms on the window surface; 2. A temperature difference occurs on both sides of the window, with the surface moisture saturation on the cooler side being lower than the vapor pressure of the surrounding environment; 3. Water vapor gathers on the glass surface and forms tiny droplets, leading to fogging.
