This may be from an overcharging battery, or more likely the battery is old and leaking. If the battery is over 4 years old, I would replace it, clean the cables real good with a acid neutralizer like baking soda.

No what you should do is clean it good, use a metal brush then use paint to paint the terminals finally use grease to grease the terminals
