How to remove the fog on the car glass in snowy days?

Method 1: Use antifogging agent to prevent fogging. First, wet the whole windshield with antifogging agent, and then wipe it with a clean soft towel after a while. Then wipe the inside of the front and rear windshields with absorbent cotton or a good cloth, and wipe off the watermark left on the inside of the glass after drying to prevent fogging.

Method 2: air conditioning refrigeration method. Using the refrigeration and dehumidification function of air conditioner, fog and steam can be removed by reducing air humidity. At this time, you can turn on the air conditioner and blow cold air against the front windshield, and use the dehumidification function of the air conditioner to slightly remove the fog and steam on the front windshield. It should be noted that the dehumidification capacity of the refrigeration system is limited. If necessary, open some windows or circulate outside to dry the air.

Method 3: Air conditioning warm air method. Car owners and friends know very well that the fog on the window is often in the cold or humid season. Under these weather conditions, the hot air inside the car will form water droplets on the glass. Then hot air can not only dry some air in the car to reduce moisture, but also reduce the temperature difference between inside and outside the window. One thing, however, is that the temperature of the glass on the back and side rises slowly, so it takes a long time to remove all the fog.

Method 4: Turn on the air conditioner and adjust it to the external circulation mode to keep the internal and external temperature balance.
