da9000, I'm no chemist, but I can tell you that I've had good experiences with Dehydrated Ethanol. I reported about that in this post, and clicking on my link in that post will take you to the exact brand/bottle I use. I don't just use it for my Mac hobby's either. We use it at the office to clean circuit boards that we repair. Works great to clean up spilled cap fluid and solder resin -- and really, just about anything you could possibly spill on a circuit board. It dries fast too, so you can plug in your electronic device very quickly after cleaning.
