Using Cold or Warm Air to Defog in Winter?
1 Answers
In winter, use warm air to defog. Here's more information: 1. Turn on the warm air, but defogging takes time. After turning on the warm air inside the car, the temperature difference between the inside and outside of the car will become greater, and the fog will become heavier. Once the temperature inside the car rises, the moisture in the air decreases, and the surface temperature of the windshield gradually increases, the fog will naturally dissipate. 2. Precautions for defogging with warm air. Defogging with warm air requires the driver to act in advance because turning on the warm air will make the fog heavier for a short time, affecting driving visibility. The driver should turn on the warm air to defog a few minutes before driving.
