How to Clean an ALR Projector Screen
ALR screens are optical surfaces, not ordinary walls. Their microstructure can be more delicate than matte vinyl, so the safest approach is to remove as little as possible and follow the exact care instructions supplied with your screen.

Start dry
For loose dust, use a clean soft microfiber cloth with very light pressure, or a gentle blower intended for electronics. Avoid aggressive rubbing across the directional surface.Do not improvise with household chemicals
Window cleaner, alcohol, abrasive sponges and strong detergents can affect coatings or leave residue. Unless the manufacturer explicitly approves a cleaning solution, do not assume it is safe.

If the manufacturer allows damp cleaning, use the smallest amount of approved moisture on the affected area rather than wiping the whole screen. Support the material so you do not stretch or deform it.Prevent problems
Keep fingers off the viewing surface during installation, avoid placing speakers or decorations where they can rub the screen, and control airborne grease or smoke in the room. Prevention is easier than restoring a directional optical material.When in doubt
Use the current manufacturer care guide for your exact screen material. The 132-inch NothingProjector uses a high-precision black-grid/lenticular material, so generic advice for a white matte screen should not be treated as interchangeable.
