The big thing is to get iopropyl alcohol, not rubbing alcool, or such. These contain a bunch of stuff other than isopropyl alcohol and water.(posted 9173 days ago)There should be no residue from isopropyl alcohol and water.
But why bother, just flick the film like a whip to get the excess water off, then hang to dry. I do use a final rinse of distilled water, then a quick dunk in distilled water and Photo Flo.
