Glass it's cold.

Maintenance knowledge of automobile glass frosting in winter

It is particularly important to maintain and prevent moderate and heavy maintenance of vehicles in winter. In winter, when it rains sleet, the front windshield is easy to freeze, especially when the temperature is below zero after the vehicle is parked overnight. Traditional medical theory holds that winter is the season of storing essence, and the saying that "three nine make up one winter, and the next year will be painless" comes from this. Similarly, it is particularly important to maintain vehicles in winter and prevent major maintenance.

In winter, when it rains sleet, the front windshield is easy to freeze, especially when the temperature is below zero after the vehicle is parked overnight. In order to remove these frost, many cars will consume a lot of time, and even cause many car owners to delay working hours.

The main reason why the car glass freezes is that there is still heat in the car after people leave the car, which makes the car glass still very hot. Snowflakes fall on the glass and the glass melts first; When the temperature inside the car is the same as that outside the car, the melted snow water on the glass begins to freeze.

How to remove frost from automobile glass

Method 1: warm air deicing

The best way is to start the car. When the engine water temperature rises, blow the windshield with warm air until the ice melts. But this method also has some shortcomings, that is, it is time-consuming, laborious and oil-consuming. If there is no rain or snow after turning off the car, you can clean the water on the windshield, which can also prevent the windshield from freezing again. If it snows, you can clean the windshield after the flameout, and then cover the windshield with a newspaper, so that you can tear up the newspaper easily when you get off the bus. Don't worry about the windshield. It's very cold.

Method 2: Physical deicing

The owner can prepare a hard plastic scraper. Of course, you can also use a special glass frost shovel. The glass defrosting shovel is more convenient and quick, and does not freeze hands. When there is snow and ice on the glass, use a plastic scraper or glass scrubbing spoon to remove it. However, Geely Global Hawk Gaomi Runfu first-class service station reminds car owners to prevent scratching the glass when removing ice and snow. Don't scrape the plastic scraper or glass frost shovel back and forth, but push it in the same direction.

Method 3: Chemical deicing

There is a spray deicer in the market, which is a kind of high-speed anti-icing spray concentrated solution, specially designed for thawing frozen windows and wipers, without damaging the surface of the car body, and can prevent icing and scaling again. At the low temperature of MINUS 30 degrees, ice and snow can be easily removed. At the same time, it can also prevent the windshield and accumulated water from freezing without damaging the surface of the car body. After cleaning, the glass is smooth and clean, leaving no stripes.

Method 4: Keep the temperature inside and outside the car consistent.

After a day's use, don't lock the car and go at once, but open the door to ventilate. When the temperature inside the car drops to the same as that outside the car (about one minute), turn on the power again and brush the snow on the windshield with the wiper again. At this time, close the door and lock the car. The next morning, as long as the snow on the windshield is cleared and there is no ice under the snow, you can start driving immediately.

Method 5: Cover the ice sheet.

It is a windshield companion in the market. Adopt national environmental protection materials, resistant to MINUS 40 degrees, double cream snow. Just cover it gently, open it gently in the morning, fold it and put it in the bag, and the hot car can start. Save time and fuel. It is the best choice for car owners who don't want to reach out and toss themselves in cold weather and love cleaning. In addition, it is also effective to cover the car in snowy days, or spread newspapers or plastic sheets on the window mats and fix them with adhesive tape.

Tips for car protection in severe winter:

1. Deicing with warm water, not hot water.

Remember not to melt the ice with hot water when the windows freeze in winter. Although hot water melts ice much faster than warm water, it is very dangerous and it is easy to burst the windshield. After all, the temperature difference is too big. Using cold water will also damage the paint surface, and frosting will be more serious in the later stage. When the ice on the front windshield is not very thick, you can wash it with a rag in warm water of 40-50 degrees for several times, then gently wipe the windshield, and then rinse it with warm water of about 40 degrees. Rub it a few times. Flushing water can generally be cleaned.

If there is thick ice on the windshield, please start the vehicle and melt the ice with warm water. When the water temperature indicator of the waiting car reaches the middle (about 70-80 degrees), blow the warm air on the windshield and turn it to the maximum. After a while, the glass will get hot and the ice will melt easily. In addition, if the car doesn't run for a while, you can drive it to the sun to dry it until the ice melts. Although this method takes time, it is also economical and convenient.

2. Cold and warm air eliminates fog in the window.

When driving in winter, due to the large temperature difference between inside and outside the car, fog is easy to form inside the car, which affects the driver's sight. There are two ways to demist, one is cold air demisting, and the other is warm air demisting. Both of these methods can help us to eliminate the fog on the glass. Of course, we need to adjust the adjustment knob of the air outlet to the air outlet position of the front windshield or press the defogging button. Because of the low temperature in winter, the way of cold air defogging makes the comfort in the car worse, so it is rarely used.

The air circulating from the outside to the car, the warm air blown by the engine after preheating, can not only demist, but also heat. In addition, there is no need to start the compressor, and the fuel consumption is naturally reduced, which is more acceptable to everyone. However, in rainy days in winter, due to the high air humidity, the effect of using heating to remove fog is not obvious, and sometimes it will fog repeatedly. At this time, the final solution is to use air conditioning for heating. Because in addition to adjusting the temperature, the most important function of air conditioner is dehumidification.
