How to defog a car is better? What if the window is foggy?

1, Emergency treatment of sudden fog on the front windshield during driving:

If it is an automatic air conditioner, just press the "front defogging" button on the air conditioner panel to defog quickly with one button. If it is a manual air conditioner, turn the air volume to the maximum, turn on the A/C refrigeration switch, and then turn the blowing mode to the defrosting position, that is, blow cold air against the glass, and soon the fog in the windshield disappears.

2. In rainy and foggy weather, it is better to give priority to prevention, such as keeping the glass surface clean or spraying some special defogging products to reduce fog. General defogging products can last for about half a month.

3, try to avoid the glass temperature is too low, if the weather is cold, you can gradually increase the air conditioning temperature, but you can't turn off the refrigeration switch at first, otherwise the demisting will be slow and the blowing will be more serious, which will affect the driving safety.

4. When driving at high speed, you can use external circulation or open the skylight a little upward. When driving at low speed, open the window to speed up the indoor and outdoor air flow and reduce the temperature difference, which will also reduce the possibility of fogging.

In addition, sometimes fog will appear on the outside of the front windshield or the outside of the windows on both sides, mainly because the air conditioning outlet blows towards the window, resulting in the glass temperature being too low. When there is fog outside, try to avoid the air conditioner blowing cold air against the glass.

In a word, the main reason of glass fogging is that the surface temperature of glass is lower than that of air. When the air humidity is high, the warm and humid air will give off heat and liquefy when it meets the cold front windshield, thus generating fog on the glass surface. It is suggested to use the defogging function of air conditioner when driving suddenly, or to take prevention as the main measure. For the sake of driving safety, it is not recommended to manually wipe the glass with a towel to defog during driving.
