Cleaning Nickel Clad Finish

I have a problem with a "green verdigris" on a nickel clad finish, it is on the inside of a sterilizer chamber. The specs on the sterilizer state the coating is 25 thousands thick over flanged steel. The sterilizer uses WFI (water for injection) or distilled water @ 180 degrees and clean steam (steam made from WFI). We are trying to remove the green with abrasive pads ( ⇦ on eBay or Amazon [affil link] ) but it is a long process. Does anybody know of a way to chemically remove the green without leaving any residue? The sterilizer is used to clean pharamaceutial componets and we can't have any contamination left after the cleaning.
