Strip PVD CrN layer

I'm trying to find a good way to strip CrN PVD later from a SSteel. Any suggestions?

A solution of 25% NaOH to which you very slowly and constantly add 25%by volume H2O2 will do the trick without affecting carbon, alloy or stainless steels. P.D. How nice city Coimbra. Just went for the first time two years ago and certainly would return.
