A few years back (don't know to where it disappeared) I had a small ultrasonic cleaner designed for the optical trade. As I recall, it was a catalog special (before the Internet) and cost about $50. By kicking up the solvent a notch or two, I was able to clean and degrease a number of gears, shafts, bearings, etc., as used in the 16mm projectors I was working on - back in the days when people actually used projectors and film instead of DVD's and LCD's. Anyway - it worked great, if you could ignore the annoying high-pitched "squeal". I usually loaded up the tank, turned it on, and went to lunch.
Would something like that be good for "green goo"? If so, would naphtha be the solvent? Acetone is more agressive, but would evaporate before I got back from lunch.
