Good news: I got a lovely 81/110 for only $10!

Bad news: there were some "video" problems that turned out to be a leaked Backup Battery. The owner said it would work but just had the video problem...well now I know it maybe a bit harder than that. Any way to salvage the motherboard? I understand that it is essentially an 8100 tweaked by Radius. Just wondering what I can do to try and fix it or clean it, sounds like it was working beautifully until that mishap.

If you guys think I should go about cleaning, I'd like some details since I don't know the first thing about cleaning mobos...

Any ideas??
