Our car glass deicing antifreeze contains penetrant and isopropyl alcohol. It provides complete protection for the glass against scratches and aging. The way to use it is simple: before use, shake the water cooler bottle and evenly spray the wine on the car windshield where frost or ice has formed. Once the frost begins to melt, wipe the liquid and loose ice off the glass. And can effectively prevent the glass from freezing to adapt to the harsh cold environment, to ensure smooth driving.
