What kind of battery?
They sale some stuff at advanced( and other auto parts store) that seems to work very well on acid cell batteries. But coke or anything with a strong acid/base effect will usually do it as well.

A dry cell, I would buy another battery. Before you damage the beeper or whatever you are using this battery in.
