I wasn't sure if there was a better forum, so I thought I'd give it a try in here. I purchased a new scanner that has a built in film & slide scanner, and I want to scan all of my family's old film. I'm starting with slides, but I'm finding that many of them are coated with finger prints. Is there a product available, or maybe even some household cleaner that is safe to use on film? I think with a quick wipe, these scans will come out looking like a million. Any thoughts? Thanks!
