Maintenance
Cleaning lenses
1. Dampen a clean, lint-free cloth with vinegar or household
ammonia. You may use water, but it will leave spots which may
be removed by polishing the lens gently with a clean, dry cloth.
Warning: Never use glass and window cleaner or any abrasive
material to clean the lens. Glass and window cleaners will stain
the lens surface. Abrasive materials (such as steel wool) will
damage the surface of the lens.
2. Starting from the center, gently wipe the lens.
Cleaning the reflector

cloth using alcohol or distilled water (alcohol is recommended).
