Many thanks,

Hi, Bob. There are many many different recipes, most based on sulphuric acid or a mix of phosphoric and sulphuric acid. The Electroplating Engineering Handbook has an excellent chapter on electropolishing, and includes some recipes you can try.

If you need qualified technical assistance you might contact Metal Coating Process Corporation, which specializes in electropolishing and conducts training schools. Good luck.
