Car defogger is useful. After spraying, it can prevent the generation of fog, and it can last for about 7 to 15 days. The main component of the defogger is a surfactant. When the defogger is sprayed on the glass, a coating will be formed. This coating can absorb the water molecules in the air without forming water mist. This will not affect the line of sight, and the driving safety can be better guaranteed.
The defogging agents of Kuaimet, Goodway, Biaobang, and E Road Chi are all good, and the price is in the dozensYuanVaries, as follows:
1. The Goodway brand has a history of almost 15 years, and the price of the defogger of this brand is relatively cheap, 200ml costs 30 to 50 yuan;
2. Quickmet is a Japanese brand, and it has a history of decades of development. Its defogging agent has a strong defogging ability, and it can last for about ten to fifteen days after spraying once.
Car owners can make a simple defogger by themselves, and use diluted detergent and soapy water to defog. The persistence of defogging is not so strong, generally only about 2 to 3 days. So it is better to buy a special defogger, which can maintain the anti-fog effect for a long time.
Other methods of glass defogging:
1. Leave a slit for the window, so that the air can circulate better, and the temperature inside and outside the car will be in a relatively balanced state. But this method is not very suitable for winter, after all, the temperature is too low in winter and it is easy to freeze yourself;
2. Turn on the cooling function of the air conditioner, that is, press the A/C button, the humidity of the air in the car will gradually decrease, so that the fog will slowly dissipate, but the cooling will increase the fuel consumption of the vehicle.
