Cleaning tellurium copper

We recently switched from pure copper to tellurium copper in some of our products. Since we drill a number of small cross holes in the part, we use a thermal deburr to remove the burrs. The copper was fairly easy to clean and make shiny. The tellurium has proved to be a challenge to get anywhere near the same finish. Any suggestions.

What have your tried before? Are you concerned about the internal holes or just the OD? Do you need a surface improvement or mirror finish?
