I recently bought one of Mattias refurbished estate pipes and I have to say that it is one awesome smoker! I love it! I want to keep the stem looking nice and sharp and black. Now I have heard that you can take some chapstick, rub it on the stem, leave it for 5-10 minutes, then wipe it off, and the stem will stay nice and shiny. Anyone have any experience with this? Does it really work? I figure it couldnt hurt. I mean, you put chapstick on your lips anyway, right?
