The electrolyte in most common household batteries is KOH
(potassium hydroxide?). We used to use dilute boric acid
(don't know the dilution%) to clean contacts on battery test
equipment.  It did a fair job, but you can expect some
etching of metal. Look for hidden damage. The KOH released
from a venting cell will run like water into cracks and
along PCBs.
