I have a recently acquired Hardcastle Royal Crown billiard that smokes wonderfully and has become my favorite (for now) pipe. But it shows its 60 years of age (I got it from ShinyPipes at eBay). Even with a furious rubbing of Dunhill Pipe Wipe, it refuses to take any kind of shine. I've heard wax mentioned. What kind of wax would help restore just a little of this pipe's former magnificence? Where would I get such wax?
