Self Regulating Electropolishing Solution: Bad News Explained

Summary for self regulating electropolishing solution Discussion

Self regulating electropolishing solution is the core question here: Thomas Kemp asked whether there is an electropolish bath for stainless steel that can run without building up dissolved iron. The only answer shown, from an unnamed contributor, says there are two broad types of electropolishing solutions—acid-based and salt-based—and both cause iron to drop out on the bottom. That implies the bath is not truly self-regulating in the way the questioner hoped, at least not from the information provided in the thread excerpt. No detailed formulation, operating method, or exception is given, so the discussion is limited and cautious rather than definitive.
