electrolysis is the cause, reaction off the lead post to the connector, clean with baking soda ( not baking powder) in hot water and smear grease over them to stop water and air ( the reaction requires water - even moist air is enough)

reason is likely the seal between battery and therminal broke, due to someone whacking on the clamp with a hammer or other tool. . next possibile reason it seperated on its own when you drive rattely roads. The fix is to fit grease patches for therminals fitted under clamps stopping the acid rise on broken seal.

The corrosion is usually a sign that the battery is on it's last legs or your charging system is overcharging causing the battery to fume.

Don't know if still available but .'felt' type washes (one red, one black or blue) the fitted over the battery terminal before putting on the clamps.Worked well for me.
