The windshield is dirty and sometime need windshield repairs because of dust, sometimes less attention, and will crystallize. In addition, residual exhaust gas from the exhaust or other pollution results that contain oil, also embedded in the glass. Various contents are accelerating the process of glass becomes opaque. Exposure the rain water on the glass surface does not directly fall, because the dirt has formed and soft layers have been fused with a layer of glass. Water is not easily washed away and attached to the glass. Especially if the night, light glow from the front so it is very dangerous. Therefore, care needs to be done as follows:

1. A first step is checking the condition of the rubber eraser’s glass from the possibility of brittle and crack.
2. Setting up water reserves and a special cloth for cleaning the rear glass can be for cars that do not have a special eraser.
Before you start polishing, clean glass with water and wipe until completely free from dust.
3. Do not clean the glass (with or without shampoo or soap) directly in the sun. Some of the shampoos containing a chemical that will rapidly absorb in the sunlight, and into the glass porous.
4. Perform polishing with a special device (cleaning fluid) to the scratched glass from the crystal dust or friction wiper rubber.
5. Every increase of water in the tube wiper, mix the liquid glass and try a special shampoo water and shampoo in a tube is replaced every month.

To repair a damaged windshield, we must use special windshield repair kits equipment. The glass is a material that is easily broken, then do not fix the glass without using the proper windshield repair kit.

Steps to perform glass repairs are as follows:
1. Perform drilling in the cracks (with a diameter of less than 5 cm) first.
2. Perform injections with diluting resin.
3. After the resin into the cavity of the glass that has been drilled, dry by using ultraviolet.
4. Furthermore, re-injected the cracks with a more viscous resin for the solid cavity filled resin cracks.
5. Do it again with UV drying.
6. After drying, the surface around the crack smeared glass cerium (Polishes glass). Perform polishing.
7. After wrapping, clean the glass.
