I had been shooting this idea around in my head and finally went through with it. The idea was to use a parts washer to strip paint off figures. I thought about getting a jewelry cleaner from Wal-mart or something, but I found something a little better. I found this on Craigslist. It is a heavy duty professional ultrasonic cleaner that has a digital timer and a heater built in. If you look up the price for this cleaner, keep in mind that I did not pay nearly that much. A fraction of the cost is an understatement. Here is it working: You are not supposed to put anything flammable inside these, but I was really wanting to try it out. I put some alcohol inside and did not turn on the heater, just let the cavitation do the work. The cavitation of hte bubbles alone heated up the alcohol to 122 F, so I see the danger of flammables going inside. I kept a close eye on it to make sure it didn't get too hot. I tried a starscream torso first, this had been partially cleaned already and I wish I took a before shot. No scrubbing was done on this piece. To give you and idea of how well it works, I tried another torso from Ramjet. Here are the before shots. Here are the after shots, again, no scrubbing whatsoever. The part only stayed in the solution for 30 minutes and there was one stubborn area where either the plastic was stained, or just some paint that needed some more time in the cleaner. I was more than pleased with the results. The parts were cleaner, no scrubbing, and less mess. I am trying another test using a solution that does not risk catching on fire. I will post those results once that test is over.
