I have been trying to figure out a way to save the battery boxes on radios after the batteries have leaked and the
green corrosion woud appear to have rendered them useless. Usually I have had to replace the battery boxes;
sometimes, through, they are not replaceable and this has caused a new problem. In one of the worse cases of
corrosion I have ever seen, I managed to remedy this by cleaning off the corrosion with white apple cider vinegar
on a Q-tip. The vinegar dissolved the green stuff, and in less then 15 minutes it was clean as ever, and like nearly
new. Use baking soda in water to stop the acid action on the metal by dabbing everything with another Q-tip.
