6.2 Cleaning Lenses CAUTION - Do not use polishes, or window cleaning aerosols and liquids for cleaning lenses. Do not touch the inner surfaces, (those facing away from the work piece), of the projection or condenser lens. The projection lens is the most critical; a finger mark on the inner surface will degrade the quality of the projected image.
Remove any accumulated dust with a photographic lens brush.
Remove any grease or finger marks with a new photographic cleaning tissue, which may be moistened with methanol if necessary.
