"Never dump" Electropolishing Solution

(2001)

Q. I am interested in any information regarding a 'self-regulating' electropolishing solution for stainless steel. By self-regulating I am referring to the ability of the solution to be operated without accumulating dissolved iron. I have seen some reference to an electropolish solution with this property, but can't find more information about this.

Thanks for your help.

A. There are solutions based on acids, and solutions based on salts. Both drop iron on the bottom.
