Quoted from snyper2099:How would you fix a sys1 board with heavy corrosion/rust on the pins then? Sometimes sanding and re-tinning is the only option besides buying a new board.
I would recommend a nice fiberglass pen like this one I got:
(Scratch Brush, Ultra Thin - BRS-290.00)http://www.amazon.com/gp/product/B002RMCFZM/ref=oh_aui_detailpage_o02_s00
It's great for cleaning up any type of electronic connection and can be used to erase off the coating on traces if you need to add a component in like an LED indicator.
