01 / IDENTIFY
Identify inside versus outside and check whether a film or coating is present. Reserve clean towels for glass.
02 / CARE
Use a glass-cleaning product and cloth permitted for that surface. Inspect in different light and separate ordinary residue from persistent deposits.
03 / KEEP SEPARATE
A window, an applied tint film and a display screen are not interchangeable. Do not jump from a streak to a blade, abrasive or household solvent.
Visibility remains impaired, a coating appears damaged, or deposits resist the normal permitted clean.
