Replacing The Lens On Lt280. Hand Oil Was 'burned' Onto The Lens.
LT280. A fingerprint was etched onto the lens while it was still warm and 'butned' onto the front lens. I am attempting to locate a replacement lens OR discover a way to clean it off. Used acetone, rubbing alcohol to no avail. Schematic parts lists would be helpful to locate part #.
