  Coke does a good job of cleaning car battery terminals but those are
lead-acid batteries and the corrosion products are entirely different from
those produced by "dry-cell" batteries (alkaline, carbon-zinc, NiCad, etc).
Dry cells use a weak oxidizer (Maganesse Dioxide) or an alkaline solution
(Potassium hydroxide) as an eletrolyte where auto batteries use sluphuric
acid.
