How to clean and maintain school bus windshield glass

The safety of school bus windshields is very important. Not to mention if the safety performance is low, it is dangerous to the occupant body, that is, to the school bus itself, if the windshield cracks or there are obvious defects, just like the face is broken, seriously damaging the appearance of the vehicle image. Therefore, the safety requirements of school bus windshields are very high. The windshield in front of the driver, the role is very important, not only to protect the safety of the driver, blocking dust, rain, sand and high-speed strong winds, but also to allow the driver to clearly see the far road conditions to ensure driving safety. On the other hand, the material of the windshield is relatively brittle and hard, as long as the surface has a scratch, it will break with a slight touch, so it should be protected well and never allowed to scratch casually. Scratch the windshield and the dust attached to the windshield wiper, this dust scratch does not look, you will find many sand glass like fine lines. When a school bus travels at high speeds, even such a fine scratch can cause the windshield to crack. In the past, many people have suddenly burst the windshield on the highway and can't find the reason, but it is those small scratches that cause trouble. (1) Cleaning method of windscreen glass The basic method of cleaning windscreen glass is to scrub with a wet towel wrung out and a dry towel that does not remove hair. When working, be sure to park the car in a place where the sun does not shine. Because if you clean the window in the hot sun, it will form water marks. This is the same as body waxing, the glass is divided into two halves, each half is up and down left and right scrub, avoid the way to draw a circle to scrub. If you find dirt, water marks or waxy contaminated glass flowing down from the roof, you can choose glass cleaner to clean, and first squeeze a small amount of detergent on the cotton cloth to wipe the dirt on the glass. Then wipe it off with a clean, damp towel. Do not spray the spray cleaner directly on the glass, so as not to accidentally spray the car body, causing the paint to fade. At the same time, do not use silicone windscreen glass cleaning protective agents on the front windscreen glass, because a waterproof agent is sprayed off the water, the wiper brush will be brushed in an extreme waterless state, so it can not slide smoothly, and the life of the rubber will be shortened. In fact, wipers and waterproofing agents can not coexist. As long as you do not need to apply windscreen cleaning protectors to other Windows or rearview mirrors, it is okay to apply once a month. (2) Remove the oil film on the window glass and wipe the door and window glass, do not use cleaners containing abrasive; Dead insects and other foreign body stains on the glass should be soaked with soapy water, then wiped off with a sponge dipped in warm water, and then washed with a soft cloth. When using canned spray oil film remover, spray 3s within the wiper sweep range and let the wiper work to quickly remove the oil film. When using a plastic bottle of oil film removal solution, remove the lid, press the bottle mouth towards the glass, and the liquid will fly out. Within the wiper sweep range of the windscreen glass, the same effect as the spray type, the oil film can be removed in a short time. Oil film remover etc. can be applied to the cloth to remove the oil film from the glass of the scraper and elsewhere (including the side window and the rear window). When there are rubber, oil, grease, silicone and other remnants on the window glass, the window cleaning liquid or silicone cleaning agent can be removed. Window washing fluid is also a safety project for rainy days and night driving. Maintenance inspection of window washing fluid is very simple. It is only necessary to inject the windshield glass cleaning liquid into the inlet of the window washing liquid on the storage tank of the windshield glass washer from time to time. This can not only remove the dirt attached to the windscreen glass, but also form a protective film on the glass surface, which has a dust-proof effect. Although the steps are very simple, but after all, it is a project that can improve safety, so when opening the engine cover in normal times. Always pay attention to the capacity and condition of window washing fluid. (3) Anti-fog inside the windshield glass Although there is no car wax and other dirt attached to the inside of the windshield glass, but someone smoking, there will be soot attached, even if the car does not smoke, the use of air conditioning, switch to the outside of the car circulation, it is possible to guide the dirty air outside, and these dirty things are the cause of the fuzzy inside of the windshield glass. At the same time, the exhaled air or the moisture on the umbrella can cause blurring. This means that if the Windows are kept clean at all times, they won't blur. When cleaning the inside of the windscreen, the best way is to cross the wet and dry wipe, and the wipe method is the same as the wipe method outside the car. When using wet wipe, the direction of wipe is up and down, and dry wipe is to replace the lamp with sunlight. From under the window to look up and wipe, if from the front to wipe, it will not be easy to find the uneven place. In addition, the inside of the rear windshield glass is covered with a fog removal hotline, and its wiping method is to wipe parallel to the hotline. If the hotline is broken by mistake, the entire rear windshield glass will be replaced, and the cost is too large. Do not use antifogging agents, as long as the moisture is not too heavy, in fact, it is not necessary. Improper application can cause blinding, blurring, or oil film. Generally, if you want to remove the fog inside the window, just turn on the air conditioning and use the outside cycle. However, in the cold winter, the temperature difference between the inside and outside of the car is large, and it is easy to form a fog layer on the inside of the glass, affecting the line of sight of the driver, you can spray a layer of anti-fogging agent on the inside of the glass, and wipe it with a clean cloth after spraying. (4) Rearview mirror water removal, fog removal, dust removal rearview mirror water removal dust removal film can be pasted on the surface of the rearview mirror, it can absorb the sun's ultraviolet light during the day, the moisture in the air on the rearview mirror to form a layer of water protective layer, eliminate the accumulation of water mist, and dust. It is especially suitable for use in subtropical climates. The installation method of this water-repellent defogging and dust-proof film is: first clean the mirror with clean water thoroughly, and then spray the water on the glass mirror and the film with a spray bottle. Put the film on the mirror, and then put the protective film on the surface of the film, and then use the blue bubble cleaner to scrape away the bubbles between the film and the glass lens. After the rearview mirror is pasted with water, fog and dust proof film, the effect is automatically generated after absorbing enough solar ultraviolet light.
