Our invisible car window crystal clear glass cleaner set contains sodium hydroxide and disodium EDTA. It can effectively resist dust adhesion and keep the glass clean. It evaporates quickly, reduces water marks, and keeps the surface smooth. Clean impurities and dust on the car glass surface, open the cap, use the cleaning brush to apply it evenly on the car glass, and finally rinse with clean water. After the liquid in the cleaning brush is used up, just add refill. It can also block UV damage and protect the interior decoration of the car.
