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.
litmus test first to see of acidic or alkaline and go for the opposite as
cleaner ?

use vinegar if an alkaline electrolytic,or sodium bicarbonate(baking
soda)solution if acidic. then rinse well,prferably with distilled
water,then some 90% isopropyl alcohol to dry.
use a cotton swab soaked in one of the solutions to test it,then try the
other on a new swab.
vias would probably wick up the solution by capillary action.
