Cleaning battery acid? Anyone know off the bat how or if one can clean off dried, leaked battery acid from a terminal?→[More:] I opened an old flashlight and one of the batteries leaked (I think it's an Energizer, the only batteries that have ever leaked on me, though not literally on me, thankfully) so it's inside and not easily, say, scrubbable and it's not rubbing off at all.

It's a good flashlight, with a fluorescent bar light opposite the handle. Like a camping light (?) not like a Maglite, although I have a big one of those, and maybe a small one... I have a remarkable number of flashlights, come to think of it.
