I greatly prefer citric acid. It comes in crystals so a small tub equals gallons of vinegar, it doesn't smell bad, and you can control the strength by dissolving more crystals into water.

It's incredibly fast compared to vinegar at cleaning battery alkaline.

Citric. Fixed!

Cool, I thought there was a pretty good chance there are acids of which I've never heard.
