Just got one of these from a pipe maker to clean the silver on my pipes. He also told me it's great for stems.

So I tried it out, and it does a great job polishing vulcanite/ebonite stems! Brings them back to a shiny deep black. Now it won't remove small tooth marks, but it does get rid of the oxydation (graying) on the stems.

Works so well that I just polished all my pipes and it made a dramatic difference. The only other way of getting a deep black finish is to fine sand, then polish using a stem polish (or alternative), and then waxing.
