This is a good little video on cleaning batteries,..also once cleaned I always put a light coat
of vasoline on all the wire ends and posts. always vent your battery compartment when charging, I just open the
door. Fumes over time in a confined area can cause corrison also. Wear rubber gloves and eye protection.
run the water gently to wash away the yucky. Remember you're washing away battery acid, clean in a safe place.
