I am a fan of cleaning my pipes with a water flush after each smoke. I have been cleaning my pipes in this manner since reading about it here around 18 months ago. As an experiment, I decided tonight to break down the tan Rubio Shape 55 that has well over 200 bowls smoked in it. This is the first time I have deep cleaned it to date. It was the first time I broke down the pipe for that matter, it was very tight.
The first photo shows the pipe cleaner, end dipped in Everclear, then run through the mouthpiece. I was shocked, nearly no residue. I ran it through several times and pushed it in and out and turned it.
The second photo is a progression, from top to bottom, of pipe cleaners dipped in Everclear run through the shank to the bottom of the bowl. Again, I was amazed at the small amount of residue build up. Most of what was picked up came from the draught hole area at the bottom of the bowl.
This further convinces me of the merits of the water flush cleaning technique. To be clear, after smoking and prior to the water flush, I run a pipe cleaner through the pipe then double it up to swab the inside of the bowl. I've also never reamed this pipe and there in a very thin layer of cake built up. It would normally take 20 to 25 pipe cleaners to deep clean a pipe with that many bowls smoked in it.
