    See the area I circled in red (in addition to several areas I did not circle). If the trace is bubbled up from the board the damaged area needs to be removed since the alkaline damage has gotten under it and will continue to destroy the trace. After removal you will need to flush the board again. It can then be repaired with copper foil or jumpers.

    Quoted from Cheddar:

    Should I try and remove the oxidation in some manner?

    Yes, the traces should all be nice and smooth like the lower (parallel) ones in the photo are. If there is damage under the traces those rough areas should come up pretty quickly w/o damaging the surrounding trace (will still need to be jumpered/repaired).

    Micro-bead blaster, Dremel tool with emery paper or an abrasive buff, electric pencil eraser, scotch-brite pad, fiberglass pen or fine grit sandpaper.
