6.1 Projector lenses
General guidelines for cleaning projector lenses
Blow off dust with clean compressed air (or pressurized air cans) .
Use lens cleaner and a clean lens cleaning cloth to remove the dust and contamination.
Wipe in broad strokes, in one direction only.
Warning: Do not wipe back and forwards across the lens surface as this tends to grind dirt into the coating.
Use a dry clean lens cleaning cloth to remove left liquid or stripes. Polish with small circles.
If there are still fingerprints on the surface, repeat with lens cleaner and a clean lens cleaning cloth, then polish
again with a dry cloth.
If smears occur when cleaning lenses, replace the cloth. Smears are the first indication of a dirty
cloth.

the projector cabinet.
General guidelines for cleaning the projector cabinet (exterior only)
