Scott, I can't help you with the paper since I haven't had much success with it either (although after reading many of Bob's posts about what to do with it I'll probably give it a try again soon), but I was going to say that, like Bob, I only use gloves to handle the prints and toss them after every print. Nitrile gloves are super cheap, and in my case, eliminated contamination problems not in the trays, but on the prints themselves. Also, it's much easier to 'snatch' prints with your hands than with tongs.
