Should You Use Cold or Warm Air to Defog Car Windows in Winter?

[OLogan]

In winter, use warm air to defog car windows. Methods to remove fog from car windows are as follows: Open windows for air circulation: Crack open both side windows slightly to allow air circulation inside the car. When the interior temperature approaches the outside temperature, the fog will dissipate. Use air conditioning to defog: Press the A/C button (A/C stands for air conditioning cooling), lower the temperature, turn on the window defogging button, and set the fan speed to maximum. As the moisture on the window surface evaporates, the window glass temperature will drop quickly, achieving the defogging effect. Use defogging spray: The principle of defogging spray is to apply a layer on the windshield, forming an effective protective film.
