To this end, the editor of this article has collected several tips for defogging in winter, hoping to help car owners.

Causes of fogging:

When it comes to how to remove fog in winter, our first step is to understand how fog is formed. In fact, frost on the car window glass and front and rear windshields is mainly caused by the temperature difference between the inside and outside of the car. The temperature difference is usually more than ten degrees, and in severe cases it may reach 20 degrees. This kind of cold outside and hot inside causes the car windows to fog up.

1. Use anti-fog products:

1. Purchase anti/defogging products

Spray on the front windshield before setting off to form a liquid film, which can effectively prevent condensation of frost mist; spray it while driving to quickly eliminate the condensation of frost mist. One spray can last about 2-3 days. sky!

2. Homemade anti-fog products

In the same way, you can also use dishwashing liquid! First pour the dishwashing liquid on a cloth soaked in water and rub it on the inside of the windshield. It can effectively keep it from fogging for about 20 hours!

2. Reduce outdoor temperature difference

1. Windshield heating and defogging:

Blow the glass directly. As for the fog on the left and right glass sometimes, you can adjust the direction of the left and right air conditioners to face the left and right glass without affecting the rearview mirror.

2. Ventilation and defogging:

You can open the car windows intermittently to circulate air and reduce the rise of fog.

Because the air inside the car cannot be dispersed well, it will cause frost and fog when encountering the cold air outside the car. Roll down some windows appropriately to allow the cold air outside the car to blow into the car to achieve convection of hot and cold air. Reduce the temperature difference between inside and outside and eliminate frost and fog. This method is very suitable when there are many people.

3. This method is more trouble-free and is more suitable in early autumn and rainy days. Remember to turn on the air conditioner first and then turn on the heating after the frost and fog disperse.

Because turning on the air conditioner can quickly reduce the temperature of the front windshield, making it impossible for frost and fog to condense, and turning on the heating air conditioner is to prevent the car owner from feeling cold.
