Harris I have one, you ought to see the crap that comes out of a pipe that is supposed to be clean, small bits of tobbaco trapped for God knows how long, cleans the shank super clean, you still need to do alcohol and salt to get the heavy tars and crap out the bottom of the bowl, I put cotton rounds my wife uses in bowl to seal the top, she"s a hair dresser and uses that to take off nail polish, you can find that at the dollar store, if you got a high end pipe blue tape around the rim, I"ve never did that , the bowl gets hot and the glue on the blue tape might stick to the bowl , don"t know.? Saying that if you don"t retort an estate or pre-smoked pipe it is DIRTY. The old cajun
