Use a battery terminal wire brush tool to clean the battery terminals and the cable terminals. Remove all old oxidized contaminants.

To prevent future corrosion, a light coating of non-conducting grease such as Dow Corning DC4 should be applied. While a professional might not recommend this, I had Japanese mechanics put regular bearing grease on my car battery terminals when I was overseas and it never presented a problem. It seemed to prevent acid build up and corrosion. | To prevent future corrosion, a light coating of non-conducting grease such as Dow Corning DC4 should be applied.
