Summary: Compared to other maintenance projects, cleaning car windshields is indeed a small job. But this is closely related to your driving view. If not cleaned properly, it can be dangerous! So how do you choose the right glass of water? First, you need to determine the freezing temperature of water in glass. If you drive to the Northeast and use 0 degree glass water, you will definitely collapse because it will definitely freeze! Secondly, you should also pay attention to the cleaning ability and anti-fog ability of the water glass. Let's take a look with the editor below! 1. How to choose glass water
Car glass water is generally divided into 0℃ glass water used in summer and -20℃ and -35℃ glass water used in winter. Its main function is to effectively clean the car. windshield. Quickly removes dust, stains, shellace, bird droppings, grease, foreign frost, etc. To choose car glass water correctly, you must first understand the difference between good and bad car glass water.
High-quality car glass water is made from demineralized water and various environmentally friendly additives. It has the functions of decontamination, water displacement, antifreeze, antistatic and anticorrosion. It can effectively remove dust, lubricating oil, gasoline and diesel, wax residue, gum, bird droppings, highway shellac, etc. It can quickly disperse rainwater on the windshield to prevent the driver's windshield from being blurred in heavy rain. It can neutralize the charge generated by friction between the windshield and wiper and substances in the air, improve the conductivity of the glass surface, resist evaporation.static electricity and prevent the charge from absorbing dirt and affecting the field of vision. The PH value is always neutral, does not contain various metal ions, and has no corrosive effect on automobile topcoats, rubber and various metals. It can quickly disperse rainwater on the windshield to avoid blurring the windshield in heavy rain. It can neutralize the charge generated by friction between the windshield and wiper and substances in the air, improve the conductivity of the glass surface, resist static electricity and prevent the charge of absorb dirt and affect the field of vision. The PH value is always neutral, does not contain various metal ions, and has no corrosive effect on automobile paint, rubber and various metals. It can form a protective film on the windshield to make the car window clearer and more transparent, without corroding the surface.face the car paint and without swelling the rubber.
The special winter glass water can also directly dissolve frost in a low temperature environment of -35°C and can quickly spread on the windshield, keeping the glass clear and bright and restoring a wide field of vision. . Low quality glass water will often appear to precipitate, change color, change taste, etc. Because the alcohol content in it is too high, it will have adverse effects on the car paint surface, damaging the gloss and hardness of the car paint surface, and causing swelling of the rubber parts and plastic parts contact, thereby reducing hardness. of these parts, and produce color differences. Since the water from the car glass will flow near the air inlet of the air conditioner after cleaning the window, the volatile odor of the glass water willwill also enter the cabin along the car's air conditioner ventilation duct. Deteriorated and moldy glass water and glass water. made from inferior chemical raw materials. The noxious odor emitted will become an invisible killer that will endanger the health of car owners.
2. Identify the quality of glass water
1. The richer the foam, the stronger the glue and stain removal ability.
It's easy to understand. Glue and stain removal mainly relies on various surfactants, and the more the better. Then, the more foaming the liquid is, the better the cleaning effect will be. To give a simple analogy: if the detergent you buy doesn't foam, do you think the stains can be removed? Therefore, when choosing glass water, be sure to shake it to see if the foam is rich. Of course, there is also an acetuce to monitor foam: The foam produced by high-quality glass water is not only rich but also fine. which is a typical anionic surfactant (environmentally friendly, biodegradable), if the bubbles in the glass of water you choose are very large and expanded (just like washing powder washed), it means that the glass of water is not environmentally friendly.
2. Antifreeze performance
To be honest, this can't be seen by looking at it. The easiest way is to look at the retail price of the glass of water. Take Zhengzhou as an example. According to historical records, Zhengzhou is the coldest city with -18°C, so most glasses of water are marked with a freezing point of -25°C, or even -35°C if the glass is water. buying free costs 10 yuan a bottle, so I can tell you for sure that it is good if its freezing point can reach -15℃. Don't youDon't aim for it to reach -35℃, which is not even enough for. the cost. Are they going to sell it to you at a loss? Therefore, it is recommended that when choosing glass water in winter, you should purchase one with a retail price above 20 RMB. The most effective way is to freeze it in the refrigerator. Generally, the refrigerator can reach -18°C. most effective for testing. In a word: quality is synonymous with price. If you want to spend less money to buy good products, it is fundamentally difficult.
3. Look at the viscosity of the fluid
High quality glass water contains a formula that lubricates and inhibits rubber wipers. Therefore, if the liquid is thicker, you can turn it. upside down glass water bottle. , observe the bubbles rising. If the bubbles rise slowly, it means the liquid is viscous, so the rubber wiper will be better lubricatedified to avoid cracks in the rubber. You can also dip your fingers in glass. water to feel if it is slippery. I think it is best to compare two different brands of water glass at the same time, so that the advantages and disadvantages can be determined naturally.
4. Anti-fog function
Professional glass water will form a monomolecular film on the glass surface, which can connect small water droplets into one piece, avoiding the generation of most water Glass do not have anti-fog function, but professional glass water basically has this function. The principle is the same as that of the anti-fog agent. Simply apply the water glass to the inside surface of the windshield or side. which does not want to fog up, the glass will not be scratched and the effect lasts a long time. Simple and practical, you can buy two products for the same price.
5. Checkwhether there are impurities in the glass water
Invert the glass water bottle and carefully check whether there are obvious impurities such as flocs and sediment. , it means that the glass water is bad and cannot be used. High quality glass water is crystal clear. Of course, any brand of glass water will expire and deteriorate. Most of the poor quality glass water will deteriorate before the shelf life expires, or due to the production formula, the production time will be different. It has already undergone chemical reaction and deteriorated at after a while. There is also a way to turn trash into treasure, which involves finding a piece of cloth to filter it through. Otherwise, the use of precipitated glass water will cause the wiper nozzle to malfunction. will be blocked!
