Abstract
Film will collect dirt, dust, and lint in a number of ways. Excess oiling of mechanisms makes the film oily and causes dirt, dust, and lint to adhere more easily. Dirt, dust, and lint flying in the air in the projection room from fans, sweepings, etc., get on the film during rewinding and projection. Static electricity generated by friction during the process of rewinding and projection causes dust and lint to adhere to the sound-track. Dirt, dust, and lint collect in the valves of both upper and lower magazines and in turn is deposited upon the film. The shaking of film reels during transportation in shipping cases lined with cardboard or other soft material causes the lining material to chip off and grind up and lodge upon the film.
