I dunno about that. Coming from a background of electronics (computers, radio, audio/video) I know that isopropyl alcohol leaves a film behind it. Just put some on a clean piece of glass, and watch what is left behind. That's why Tascam markets their own head cleaner -- it contains no isopropyl alcohol.(posted 9367 days ago)If you don't want to use Kodak Photoflo, there's Edwal LFN in distilled water, or just distilled water. (There's another one which will advertises that it will completely dry the film in just minutes, but the name escapes me.)
