rodent nests

So the good news is I've stumbled upon a Frankin Ace 1000 and a TRS-80 Model I with EI unit, 2 machines which I've been looking to acquire. Better yet, both are FREE! The bad news: some sort of rodent(s) decided that the shells would make nice homes and built nests in them. I popped open tha Ace, haven't had the heart to check out the inside of the EI yet. Most of what was in the Ace was bedding and shells from eaten nuts. These came out easy enough. All wiring seems to be intact and uneaten (the back of the case did have its card slots widened by rodent teeth however -- not a big deal). There wasn't really any droppings as I imagined there would be, but there is a brown film that is on much of the motherboard. What is this (urine, oils from their fur, some other sort of bodily excretion) and is there anyway to clean these systems and try to recover them? __________________________________ Do you Yahoo!?
