How to Defog the Car Interior?

[GriffinRose]

Methods to defog the car interior include: 1. Open windows for convection, allowing air circulation to equalize the temperature inside and outside the car, which naturally dissipates the fog; 2. Use the air conditioning in heat mode to evaporate the fog inside the car; 3. Dilute dishwashing liquid with water, dip a clean cloth into the solution, and apply it to the windshield; 4. Use glass anti-fog spray. The reasons for fog inside the car are: 1. Under certain humidity conditions, when the window temperature is lower than the dew point, condensation forms on the window surface; 2. A temperature difference occurs on both sides of the window, with the surface at a lower temperature having a saturated vapor pressure lower than the surrounding environment's vapor pressure; 3. Moisture gathers on the glass surface and forms tiny water droplets, creating fog.
