I actually do a pre-wash of my films, roll and sheet, however; it's not for 5 minutes. Wasn't sure how that would affect the film. I develop my roll/sheet in a patterson tank. I do a pre-wash on each which is fill, and swhoosh around, and dump 3 times, then I'm ready to put in my developer.. I'll try to extend my pre-wash longer on my roll film now, and see if that helps.
