Well, I've de-railed my own thread here, so let's put it back on track!
I spoke with Troy a few days ago and he said he's now using lacquer thinner to clean parts. You just have to be VERY careful with it. Use it outside, not in direct sunlight, etc... but it seems to work good. He said that if you leave parts in it too long, it will discolor them, so you have to keep an eye on it, but other than that, it works just fine.
I'm going to give that a try so I'll report back after this weekend.
