try pec-12. works for me every time. takes some experience though to get it right, especially with bigger film. try it with some pec pads and a rocket blower(or a baby nose blower/sucker thingy) you can get those at your local pharmacy. ask the pharmacist, they may give you one for free. mine did a year back. so I don't really care if I lose it, cause it was free .
I generally use the canned air, I used to print at a place that had hookups to a compressor in every color room, so it was nice and convenient for that purpose.
go easy on the pec-12 though... you DON'T need a lot, just a DROP or TWO on a pec pad. nothing more. definitely not soaked!
