A. Question to you, is your bath homebrew? If so why the lactic acid? jon

A. Kathy: Foaming of electropolishing baths can also be caused by drag-in of organic materials, such as lubricating oils. Are you cleaning the parts adequately before electropolishing?

We have some foam suppressants available, but the most effective treatment is to remove the organic contamination.
