Not sure what i used in school. But stuff I sprayed on film and whiped with a special tissue. just got a film scanner and want to prep my film that way before scanning to clean dust and stuff off the film. Any suggestions would help.
Load it on a reel and run warm (not hot) water on it for an hour or two. Finish up with a couple of dips in distilled water. That's pretty much the only really safe way to do it. Emulsions are soft and wiping film with anything at all can scratch it. All it takes is one tiny bit of grit. The special tissues were probably Kimwipes; the manufacturer says Kimwipes can be used on film, but knowlegable photographers never use them for film. My photography teacher would drop you a grade if he saw you doing that. We only used them for cleaning gear.
If you wash the film and finish up with distilled water, there will be no spots when it dries, so there is no need to wipe the film. Just let it dry naturally. Yeah, school teaches you to do all kinds of things that pros won't do. Amber lights, RC paper, wiping film, 5-minute print washes ...
Compressed air from a compresser works; the stuff from a spray can can ruin film. There is rusty water in the bottom of the can and the propellent can cause freeze damage.
