I just finished reading it, and I did get one post in... but, I'm glad that guy is gone.
There are lots of threads about this, and different members have different ways to go about it. I don't use very hot water, but some guys do. I just hold the pipe chamber to the spigot of the sink, run water through the pipe and out the stem for a few seconds. Then I use a wadded paper towel to ream out the chamber, take out the stem, and run a cleaner down the stem, and into the stummel. I then buff the pipe with a clean towel, rub the rim over a piece of leather, buff the stem a bit with a jeweler's cloth, reassemble, and rack the pipe.
I can do twelve pipes in just a few minutes, usually doing all of my pipes that I have smoked throughout the day at one time before bed. But, the pipes has a fresher smell, keeping the cake beaten back, and my pipes all look fantastic.
But, if this scares someone, or gives them anxiety... or if removing a stem terrifies someone, maybe avoid it.
