Excuse me, because the window is closed in winter, the front glass will produce fog and block the line of sight. If you roll down the window, it will be very cold, and it is not safe to wipe it with steps. Turn on the air conditioner.

Use a special defogging agent.

There are special defogging agents in the decoration and beauty market. Spraying this defogging agent on the inner surface of automobile glass and wiping it clean can remove glass dirt and form a thin transparent protective film on the glass, which can effectively prevent the fog layer formed by water vapor condensation on the glass. Spraying it once can prevent fog for about 10 day.

The second skill of defogging

Blow hot air while turning on cold air.

In fact, many car manuals have introduced the methods of defogging, one of which is to adjust the air outlet of the air conditioner to the windshield, turn on the air conditioner switch, and let the compressor work so as to dehumidify. But at this time, if you turn the temperature control knob to the cold wind gear, the people in the car will definitely be too cold to stand, so you can turn the temperature knob to the warm wind position to achieve the purpose of both defogging and heating.

The third measure of defogging

Cleaning method of detergent window

In fact, the defogging agent is prepared by ourselves, and the method is also very simple: the tableware detergent is mixed with water according to the ratio of 1: 10, and then dipped in absorbent cotton or soft cloth and applied to the inside of the front and rear windshield and the mirror surface of the rearview mirror. After drying, the residual fibers left on the windshield can be wiped off with suede or soft dry cloth. Although it is not as effective as the special defogging agent, it is indeed an economical and practical one.
