I used about a 30% solution of isopropyl from the drug store to help quicken the drying of film. It worked okay. I used to use ISO_HEAT which you use to dehydrate gas lines which was almost 100% alcohol, but after 2 years or so the added some oily stuff that totally ruined the films. Same with the blue nail cleaner, it has amyl acetate, among with some oils in it --I wouldn't trust it-- probably melt the film
