Pulling the film off the reel before photoflo'ing it will often cause fine scratches where the corners of the film rub against the emulsion. Leave it on the reel for protection while it's in photoflo; a quick rinse under the hot tap will completely clean the reel once the film is hung up.
Well then you have a problem. You eventually have to remove the film from the reel to use it. Just be careful, never had a problem.
