Hi all, I'm working with an inherited Optemus II enlarger. It has a nice negative carrier that adjusts from 35mm up to 2x2. The problem is that the film sits between two glass plates, and the glass is an unbelievable dust magnet. I can pretty well get all the dust off the film, but dustlets (hair, black dots) appear out of nowhere and adhere to the glass, usually the upper one, and on both the outside and inside surfaces. I clean one off, reload the carrier, and there's a new one. So far I've tried an anti-static orange cloth, an antistatic brush, eyeglass lens cleaner, warm water with dish soap, canned air, my fingers. and liquid film cleaner. I'm not sure I've found the right cloth to dry it off with when I use one of these liquids--have been using lint-free darkroom cloths. Any ideas greatly appreciated, before I chuck the equipment.
