cleaned leaks

Cleaned a LED lid light double-AA battery pack of leaked battery goo. Couldn't remember how to do it, at first. Looked it up on the interwebs (potassium hydroxide which is an alkaline). Right, use an acid. Checked with Mr T, the chemist, but he was thinking of lead acid batteries. Started looking around for vinegar but couldn't find any! I asked what household stuff I could use to make an acid (we forgot about citrus fruits). Tony suggested red vinegar. Ah ha! Found some in the spice cupboard. Toil and trouble. Bubbling! He said, "It's working." Then rinsed well. Good as new. Tested with some spare AA batteries on the desk. Back in service.
