The windscreen is a very important part of any vehicle, through which the driver evaluates the road situation to make decisions. In summer, the glass can be kept clean using regular water, but in winter time this obviously will not work. The windscreen wash system can be ruined by the freezing water.

Special non-freezing liquids are used in the cold season. A good quality of the washing liquid can handle glass cleaning even in cold weather, and efficiently remove dirt, film and ice.

So what are the ingredients of window wash liquids? First of all, they include surfactants, with washing effect. To keep the glass clean, a 1-2% surfactant solution is sufficient. Aromatizers and dyes are also needed. The former remove odors, the latter make the product look better. Water is also important: distilled water is the best choice. Regular tap water does not work, because it will cause sediment of mineral salts and chalk, scratching the windshield glass.
