OPTIGLASS is a glass cleaning product, with water-miscible solvents that cut the greasy film of the glass quickly leaving them completely clean. It does not contain soap or ammonia, so it leaves no marks or residue. With double action, it can be applied pure or diluted. Diluted, cleans instantly and prevents dirt, excellent and safe for tinted windows. Undiluted has the same cleaning capacity, but in addition, it creates a water-repellent film on the glass that repels water, not allowing it to stick when it rains, significantly improving day and night visibility.
