Response to watermarks on negatives

I agree Isopropyl works, but there are cheeper alternatives. I use either a wetting agent ( Ilfotol 1:200, but any other would do as good) or simply give the final rinse in destilled water. I think this is the best. If you use alcohol, be aware that any impurities will soak into the emulsion and eventually cause archival problems, so the alc. should be of the highest possible grade.
