Default Cleaning leaked electrolytic & corrosion on PCB

DaveC wrote:
What is the best method for cleaning up leaked electrolyte? This PCB has some
corrosion on IC leads and vias.

Is there a corrosion neutralizer that would be effective? Since the potential
for corrosion in places that aren't accessible (deep in the vias), a liquid
that can neutralize corrosion is called for.

Would something like DeOxit work in such an application?

This is on a Tek scope acquisition board.

Thanks.



I scrub with white vinegar and a toothbrush, then rinse with alcohol. If
the corrosion is more severe, mechanical methods may be needed,
Scotchbrite type cleaning pads work well but you have to be careful not
to damage fine traces. In some cases it's best to neutralize and then
clean off as much residue as possible and then leave the remaining
corrosion alone.
