FOR REMOVAL OF CARBON RUST YOU CAN ENGAGE A TANK POLISHING COMPANY FOR "PASSIVATION" DURING WHICH THEY (1) APPLY AN ACID THAT CONSUMES IRON OXIDES THEN (2) RINSE AND (3) PASSIVATE TO RETURN THE NATURALLY OCCURRING FILM TO THE SURFACE.

Hi usually to remove surface rust from 316L stainless use a solution of acetic acid (vinegar) and use electrolysis with 12 volts and the piece needed to remove the rust from on the negative side and another piece of similar material like a piece of scrap material-same grade on the positive side
