What is the principle of automobile glass freezing in winter?

There is still hot air in the car after we stop at night. When the external air conditioner meets a slightly higher temperature at the glass, it will melt, and then interact with the external air conditioner during the melting process and condense into ice.

In winter, the front windshield is easy to freeze when it encounters sleet, especially when the temperature is below zero and there is water after the vehicle is parked overnight. How to effectively and simply remove ice from automobile glass? When there is ice, two methods are suggested: one is to scrape with a bank card or a hard plastic card. Be careful not to use too much force when scraping, and scrape in the same direction to prevent scratching the glass. Before scraping, it is best to start the vehicle, turn on the warm air in the vehicle, and remember to turn on the defogging function of the glass, so that the warm air can blow the frozen glass away, melt it first, and then scrape it. Turn on the warm air step by step from neutral 1 gear to fourth gear, and take your time. The effective way to prevent the car glass from freezing is not to leave in a hurry after using it the day before, but to do everything possible to disperse the hot air in the car, and the effect is good. Cooling mode: Open the four doors and ventilate for two or three minutes, the temperature inside the car will drop and it will not freeze the next morning. There is also a "dress" on the car body: covering the front windshield with a cloth, covering the rearview mirrors on both sides with plastic bags, or sewing a cotton cover with elastic bands are all effective. Usually take it down and put it in the trunk when not in use. The other is to be careful not to burn the glass with warm water or hot water, which will crack the glass and cause irreparable losses. In addition, you can buy a spray snow remover in the market, which is very convenient to use and will not damage the surface of your car.
