Our automotive glass film cleaning agent contains brightener, corrosion inhibitor and propellant. It can effectively break down stubborn stains such as oil film, water stains and glue stains on the glass. The usage method is very simple: Take an appropriate amount of this product and squeeze it onto the glass or a sponge. Immediately wipe back and forth with the sponge or towel. Rinse with plenty of water and dry with a towel. After cleaning, the glass will be refreshed and a protective layer will be formed, allowing water droplets to roll off, preventing rain and water damage.
