What, chemically, is that whiteish crumbly powder on bad batteries?
We all have seen it, and most of the time you can just brush it off, but
I have it on a device deep inside that I can't get a brush on without
breaking stuff.
I'd like to use a solvent (I already tried water but I want to do a
better job) that dissolves the stuff so knowing the chemistry might help.
Do you have any idea what the chemical composition of that stuff is?
Potassium Hydroxide - an alkaline (Alkaline batteries after all). Wash
off with a mild solution (50/50) of white vinegar and water, scrub, and
rinse with clean water carefully.
