As everybody knows I'm just an anal clean freak and like my pipes to sparkle all the time.
After each smoke I run a cleaner through them and wipe out the bowl with a paper towel, no scrubbing just insert it and a twist, then I wipe it done with a soft cotton rag and I'm done. Although I only smoke one bowl out of each pipe a day for two days, then I go to the next 3 pipes in rotation (I have 3 bowls a day). When I come to the end of my 14 pipes I start all over again. Confused yet, I'm not. At the end of the month all 14 get a thorough cleaning, ISO, wax and buff and anything else they might need like rim cleaning and maybe a ream depending. I don't do this because some old timer told me to and, I don't do this because I read it somewhere, I do it because I want to do it this way and don't really give a hoot in hell about what's suppose to or not suppose to be done. It works for me!
