Alcohol can also be an effective liquid to use in cleaning corroded battery terminals, as they contain elements capable of eliminating corrosion and rust on battery terminals. A classic example of such alcohol is Isopropyl alcohol. Suppose your vehicle’s battery terminals are corroded because the vehicle was packed or the battery was kept somewhere for a long time. In that case, you could use Isopropyl alcohol to remove such corrosion and use the battery again.
