How do you get rid of battery corrosion?
If you're not talking about a car battery then ignore this, but if you are, they make battery post and clamp cleaners. http://cgi.ebay.com/ebaymotors/2-pc-ALL-METAL-BATTERY-POST-TERMINAL-CLEANER-WIRE-BRUSH-_W0QQcmdZViewItemQQhashZitem45f7d3e907QQitemZ300510603527QQptZMotorsQ5fAutomotiveQ5fTools
You scrape off the battery corrosion, with anything you have handy. If the corrosion is bad, take a file and scrape it off. Your battery will love you, if you get rid of the corrosion. The battery will run better, when it is free of corrosion also.
In a pinch you could use coca cola trust me it works!
Can of Coke ears right through it.
Baking soda also works. Just mix it with a little water and pour it on.
