How to Deal with Fog Inside a Car's Windshield?

[Sanchez]

Solutions for fog inside a car's windshield: 1. Open the windows to allow air circulation; 2. Use specialized defogging products, such as defogging sprays or defogging towels. Spray these defogging agents onto the inner surface of the car glass and wipe them clean. This not only removes dirt from the glass but also forms a thin, transparent protective film on the glass; 3. Use the car's one-touch defogging function. Most cars equipped with air conditioning have a defogging feature—simply press the defogging button. Fogging on the windows mainly occurs due to temperature differences between the inside and outside of the car. When the saturated vapor pressure of water on the colder surface is lower than the surrounding environment's vapor pressure, moisture gathers on the glass surface and forms tiny droplets, leading to fog formation.
