The domestic automobile market is booming, and joint ventures and independent brands are developing smoothly. In fact, in the past, most people would not consider domestic cars. After all, the quality and reliability of domestic cars are not as good as those of joint ventures.

With the rise of independent brands, all aspects of strength can gradually compete with joint ventures. Of course, the price of cars is becoming more and more transparent. It is not difficult to find that the price of the same paragraph in the same city is basically the same. In this way, the way that 4S shops used to earn profits from car prices no longer exists, so they will transfer their profits to other aspects, such as maintaining car insurance.

Especially in terms of maintenance, although many people will choose to maintain in regular repair shops after the first insurance, most people will choose to continue to go to 4S shops for maintenance. Although the price is more expensive, the quality of service and accessories is more reliable. However, not all insurance items must be carried out in 4S stores, and some are unnecessary at all.

First, we need to know what glass water is made of. What's the role? Generally speaking, glass water contains alcohol, ethanol and corrosion inhibitor in addition to water. If you drive at night, there is too much dust on the windshield, which will scatter light. At this time, spraying some glass water can make the glass more transparent. Glass water not only has cleaning function, but also has anti-freezing, anti-fog, anti-static, lubrication, anti-corrosion and other functions, which is very important for windshield.

Therefore, it can be seen from the function that tap water can only play a cleaning role, and the effect is not good, which can't be compared with glass water at all.

But in an emergency, if there is no glass water, tap water can be used instead, but it can't be used for a long time. If tap water is used instead of glass water for a long time, it is easy to adsorb dust besides static electricity. Without lubrication, the glass will be easily scratched, and the windshield will be basically destroyed after a long time. If it is replaced, it will undoubtedly increase the cost, and the loss will outweigh the gain. Of course, there are many kinds of glass water, but they can be roughly divided into three types.

One is commonly used in summer. Adding insect repellent glue to the cleaning solution can quickly remove the remaining flying insects on the windshield.

The other is commonly used in winter, belonging to antifreeze glass water, which will not freeze even if the temperature is below 20 degrees.

The third type is a special anti-freezing type, which has better anti-freezing effect than the second type, and will not freeze at MINUS 40 degrees, so it is very practical in the north, especially in the northeast. When adding glass water, the owner can add it himself.

The operation is simple. Just open the engine compartment and find a special place to fill the glass water. There is a blue windshield-like cover on it. Some cars may not be blue, just remember that there is a windshield sign on them. Then open the lid and pour the glass water directly. Don't add it too quickly to avoid overflowing. After adding, cover and close the engine compartment. The whole process basically takes no more than 5 minutes, which is very simple, even if the car is white.
