White streak marks in electropolishing 316L

We are currently electropolishing cube of 316 L SS and we getting the walls mark with streaking marks but also some of them come out fine; does anybody has suggestion on solving this problem? I can e mail a picture of the wall.

In my experience the streaking if your talking about a cream like haze, is usually from not getting all the solution rinsed off, If you do not put your rinse back into your EP Tank you can add 1% ± Nitric Acid to the first rinse and should help with your problem.
