What I'm most concerned about removing is some white silicone that was used as a glue for neoprene on the back of the board. The neoprene is somewhat torn, and it is blocking repair work on the wires for a Palomino die temp reader, and it's also a little thick for some of the plans I have for this board.
Ideally, I would like to clean up around the socket as well, but I've mostly gotten that cleaned up with a razor blade and a soft plastic scraper.
I would like to have it all pretty and clean again though.
