It's foggy outside the window. No need to blow warm air? It took 10 years to know that a stupid move made the window HD without code.

There is an old saying that everyone often says, "Look at all directions and listen to all directions". Many people will certainly often hear the coach say this when learning to drive. It is usually used to describe people who are resourceful and flexible, and can observe and analyze things from many aspects, so we are also good at driving. It is very important for a person to see all directions, especially when driving. Only by seeing the situation around the road can he drive more conveniently and better. If the line of sight is blocked, it will definitely affect the driver's driving and easily lead to traffic accidents, so this is also the reason why they should travel less in rainy days. In fact, in addition to rainy weather, fogging of windows in winter is also a headache for drivers. Fog will blur the driver's sight and the road ahead, which has a great influence on driving. Today, the old driver will tell you what to do if the window is foggy.

There are four seasons in a year, with different temperatures in spring, summer, autumn and winter. Careful people will find that in autumn and winter, there will be a thin layer of fog on the window, but this will not happen in warm summer. The fog will hinder people's vision and can't see the surrounding situation clearly. There must be many people wondering why fog only appears in autumn and winter. Its principle is simple, because the temperature outside is different from the temperature inside the car, and the air forms water vapor on the window. In order to get rid of the fog, most car owners will turn on the air conditioner and blow warm air to make the water vapor on the window evaporate, but this will make people sleepy and dangerous. Listen carefully, let the old driver of 20 years teach you a few tricks, and you can remove fog without turning on the heating.

The first trick: defogging agent for automobile glass. You can buy glass defogging agent online or in auto shops. When driving, you can spray it on the windshield to clean it, which will form an oil film protection layer on the glass, and there is no way for air to adhere to the windshield. The general effect of this cleaner can last about 10 days, and the price is also very affordable. You can take it with you when driving in winter, and spray it when it is foggy, which is a more radical way.

If you don't want to buy it, you can also make your own defogging agent for car glass. Dilute water and detergent according to the ratio of 1: 10 to 1:6, put it in a small watering can, spray it on the windshield when driving, and dry it with a cloth after one or two minutes, and the fog will disappear, so it will not fog when driving. Its effect may not be as good as that of special demister, which can only last for about one day, but it is also simple.

The second measure: convection defogging method. Haha, simply speaking, it is to open the window and blow cold air. This is the ultimate way for old drivers. Fog is produced because the temperature outside and inside the car is different, resulting in differences. According to this principle, there are two methods, one is to raise the temperature of the glass to the same as that in the car, and the other is to adjust the temperature inside and outside the car to the same. The first method, as the old driver said above, is not feasible to turn on the heating to raise the glass temperature, so we can take the second method, blowing cold air while driving, opening the window to let the outside air into the car, so that it will not fog, which is the so-called convection defogging method. The driver doesn't need to turn on the air conditioner at all. When there is no fog, he will open a small gap on both sides of the glass so that the air inside and outside the car can convection, and the temperature inside the car will gradually approach the temperature outside the car. It won't be long before the window lights up. Of course, the bigger the window, the more obvious the effect. I would like to remind everyone here that it is not suitable for use when it rains at high speed, otherwise it will definitely be frozen into slag unless there is an emergency.

Of course, some car owners have convenient maps. When the window is foggy, wipe it with a cloth or get started directly. This is actually a very unsafe behavior, and it is very dangerous to deal with it in an emergency. When the window is foggy, you can use the above method. For your own safety, the simplest and safest thing is to open a small crack in the window. Don't get started just for convenience.
