Blue Battery Terminal

Today I had a few hours to kill. Did general check up on my wife's car. When I open the Bonnet, WoW, what did I see, Blue-greenish flakes surrounds the Battery +ve Terminal. Got a shock!!. This is actually a thin film of sulfuric acid. If left un-check will eventually lead to corrosion of metal parts around the battery. It can be cleaned away easily before it causes problems. If corrosion is ignored, it can damage battery cables and holddown parts and lead to operating problems, such as a no-start condition.













This blue-green flakes are corrosive !!!













Remove the terminals ( -ve) first, then remove the (+ve) side. Ensure no spill of the corrosive flakes. I then remove the +ve cable that connects to the start-motor. Did a good wash on it. Use lots of running water. Use eye-protective goggles. Then wash the battery mounting areas. You do not want any residue of the flakes to starts "eating" your paintworks and subsequently your car metal parts.













Washed thoroughly the cable connectors and the terminals. They look ok now. Then install back the cables and the battery.
This time I apply a layer of grease to protest both the +ve and -ve terminals.













This cleaned terminal and connector will give you a "one-Kick" start.
