yep give it a clean up.
if you can take a few pics of both sides of the pcb in the acid damaged areas.
you may have several tracks that need to be repaired.
also you will need to remove all the corrosion and clean the board in that area so the copper tracks are nice and shiny, then you will have to check that all the tracks in that area are not corroded threw.
then after you have repaired the damaged tracks you will need to seal the pcb with some clear pcb laquer.
dont do any thing yet. i will see if i can find some posts on this subject and post the links here.
