[sdiy] Board Corrosion

[carlile at ece.utexas.edu]

I'm working on restoring a CAT and there is heavy corrosion in one corner of 
the main PCB.  The filter/VCA board looks great, so I assume something was 
spilled on this corner.  Most of the traces check out fine with a continuity 
meter, but a few are damaged.

I've tried spot applying deoxit, denatured alcohol, rubbing with a pencil 
eraser, and rubbing with fine steel wool and it won't come off.  Is there 
anything else I can do?  I'm replacing most of the components, so the thought 
of having it bead blasted has crossed my mind, but this might be too much as 
it could damage the traces.  Should I just solder jumper wires where needed 
and forget about it?  Any advice is appreciated.
