In winter, cars parked outdoors for a night and windshield frost often occurred the next day, which is probably one of the biggest headaches for garage owners. In this regard, experts reminded the majority of riders: car defrosting is not suitable for collision, wisdom is often more effective than brute force. In the cold winter, when the car glass is frosted, the safest method in the traditional method is to warm the car in advance with warm wind blowing frost, but this method takes a certain amount of time.
It should be noted that the frost on the glass cannot be scraped with snow shovels, cloths and cards. Because the winter wind is relatively large, there will be many small dusts in the frost. The result of using a tool to wipe frost is to sand the glass with fine sandpaper, and your window will soon become frosted glass. Also remind you that you can't use cold or hot water! Because water is poured and cold water freezes the glass, hot water can directly cause the glass to burst. As for the practice of some riders defrosting white wine or alcohol on windshields, our experts are not recommended. If the wine is spilled, the drink directly flows down the deflector, which causes the alcohol to come into contact with many rubber parts on the body, causing some corrosion or damage to the rubber parts. Therefore, this method is not recommended.
At present, some anti-frost methods have been favored by many riders. For example, a car owner can cover a vehicle with a professional car after parking in the evening. Here we do not recommend newspapers and ordinary cloths to block the glass, because in cold weather, such items may be frozen on the glass or blown away by the wind. Another way to take precautions is to open the windows or doors before the parking spots are about to reach the parking place at night, or to stop the car, so that when the temperature in the car drops to the outdoor temperature, the window is closed, the door is closed, and the car is locked. The temperature difference, the water vapor in the air will not be easy to condense in the window, so you can prevent frost from the source. In winter, the temperature is low. When you get up and drive in the morning, there is often a thin layer of frost on the glass. It is not easy to remove it. How to get rid of the mist or frost attached to the glass faster and better? Here are the tips given by professionals!
Defrosting and defrosting of automotive glass: In the morning, it is found that there is a layer of fog on the glass of the car. The main reason is that the glass of the car is in contact with the outside world. The temperature is low and the water vapor in the car condenses on the glass. To remove this, Fog, there are two ways, either to increase the temperature of the glass, or to reduce the humidity inside the car. Professionals of car decoration and beauty shop reminded that in fact, many car manuals have introduced the method of defogging, that is, the air conditioner tuyere is transferred to the windshield, the air-conditioning switch is turned on, and the compressor works so as to dehumidify. However, if the temperature control knob is turned to the cold windshield at this time, people in the vehicle will certainly be too cold to stand. Therefore, the temperature knob can be placed in the warm air position to achieve the purpose of both defogging and heating. The automatic air-conditioning defogging operation is very easy. Turn on the automatic air-conditioning and switch the mode switch to the defogging gear. At this time, the air-conditioner is automatically converted into an external circulation, fresh air enters the cab, and defogging begins.
If it is a manual air conditioner, the wind direction switch should first be adjusted to the defogging gear, and the external circulation should be started so that the fresh air can be blown in. When the compressor and the wind speed are adjusted to the maximum, the dehazing speed can be accelerated. If you feel that the defrosting of the side glass is not fast enough, it is better to close the two central air outlets so that the airflow at the outlets on both sides can rapidly blow up the fog. You can also open the window to speed up the defogging. In addition, special defogging agents can also be used for defogging, and the greatest benefit of this defogging agent is "anti-", so it is particularly useful when driving.
Professionals introduced a special glass cleaner anti-fogging agent sprayed on the car glass, and wipe clean, while removing the glass dirt, but also on the glass to form a thin layer of protective film, which can effectively prevent water vapor in the glass The fog formed on the condensation is generally sprayed once a day for a period of time. The mist is better dealt with. If the weather is too cold, in the morning, it will feel that the glass of the car has been “frozen†and the surface is covered with a thin layer of frost. When it is cleared, the car will be started first. After the water temperature comes up, use hot air to block the wind, etc. Blow the ice on the windscreen and wipe it with a wiper. Waiting for a long time before you can drive on the road. It is really troublesome. Is there any good way? The reason the car glass is “frozen†is that after leaving the car the night before, hot air remains in the car, making the temperature of the car's glass higher than the outside of the car. If the outside temperature is too low or it is snowing, the snow falls on the glass. Melting first, when the temperature of the car gradually decreases to the same temperature as the temperature outside the car, the snow melting on the glass begins to freeze, and the snow that falls after freezing will no longer melt. The quilt covers the surface of the ice: "In the morning when driving, the snow on the glass is very clear, but the frost below is not good."
The more clever way is to use the car to stop, do not immediately lock the car away, but to be patient and wait for a while, open the ventilation on both sides of the door, wait for the temperature inside the car to drop to the outside temperature is almost the same time, open With the power supply, wipe off the remaining snow on the front glass with a wiper, and clear the snow the next day without worrying about the annoying frost. Frost on the rear window glass is better dealt with, most cars are equipped with a rear grille defroster, defroster work will consume battery power, when used, we must first start the engine, and then press After the rear window defogging switch, the defroster will automatically close after 10 minutes.
There are other ways to defrost cars in winter.
1. If it is frosting while parking, start the car with hot water or start the car in place.
It is recommended that you go home at night and park your car to open the door and heat it up. When you lock the car, you won't be blooming.
2. If the glass starts to bloom, clean the glass with a clean cloth or newspaper and perform the following operations:
Winter: When the cold car is just started, the two doors of the front door are slightly shaken to reduce the temperature in the car so that the cream will not condense on the glass. After the car temperature rises, the mode will be opened to the inside of the car and the blower will be hot ( Small frost does not need to open the air conditioner) Open the (wind cream size adjustment gear) blow the glass, the cream will be scattered.
