How to eliminate glass fogging in winter driving

[China Glass Network] With the temperature drop, the winter temperature and precipitation, for many car owners, the window, especially the front windshield fog is a headache, how to avoid this phenomenon?

First, the use of special defogging agent

Special defogging agents are generally available in the interior decoration beauty market. Spray the defogging agent onto the inner surface of the car glass and wipe it clean. The defogging agent can not only remove the glass dirt, but also form a transparent protective film on the glass, which can effectively prevent the water vapor from condensing on the glass to form a fog layer, and generally sprays a sustainable anti-fog day.

Second, blowing hot air while blowing cold air

In many car manuals, the method of defogging is introduced. One of them is to adjust the air conditioning vent to the windshield, open the air conditioner switch, and let the compressor work to dehumidify. However, if the temperature control knob is adjusted to the cold windshield at this time, the person inside the car will certainly be too cold, so the temperature knob can be placed in the warm air position to achieve the purpose of both defogging and heating.

Third, the detergent window method

Detergent contains a surfactant, which can change the surface tension of water, so that the droplets quickly condense into large water droplets, which can play an anti-fog effect, which is an affordable and simple method. However, this is a preventive measure that must be dealt with in advance. If it is found that the fog is coming again, it is too late.
