Thanks for the replies. Though I do like to keep my tools working and looking really good, I don't believe I've yet reached the point of OCD about it. As I mentioned in my first post, this was a new tool, and had quite a lot of oil in it, presumably to keep it from rusting on the boat. The first exhaust of the tool created a splatter the size of a piece of New York pizza. I was able to wipe some of it up, but this happened 2 days after I came home from the hospital with my second child, and I didn't have much time to give it any attention, since I was trying to finish up a good paying job, and my time in the shop since then has been all but non-existant.
I'll give the lacquer thinner a go. I've done some baltic birch plywood work on it since the spill (non-critical work - will probably end up being painted) and can't see any oil transfer, but that doesn't mean there isn't any.
