I have a few older SCR type sub C packs that I would like to use in some shelfers, but they are showing signs of leakage. You know, crusty white junk around the shrink on the individual cells. Does anybody know what would work to either stop the leakage, or neutralize the growth of this wonderful stuff?

Vinegar should break it up and remove it- total discharge should help prevent re-occurance I believe-
