[Elecraft] Cleaning capacitor goop from PC board

[Vic K2VCO]

I have a board (not an Elecraft product!) which has several SMD electrolytics that have 
failed, leaking brown, corrosive goop. The board is hard to find and expensive. I am going 
to try to fix it.

Question: how do you clean the brown capacitor goop off the board?  Some of the traces may 
be corroded, but I can't tell without getting this stuff off! And I don't want to damage 
them by scraping.
