I'm not a fan of bristle cleaners, because they can scrape and bugger up the draft, possibly causing disturbances for condensation to form in there. Maybe, maybe not... but...
Anyways, I find it odd that the regular pipecleaners are so narrow, and you guys like that. I prefer the pipecleaner to make contact with the sides of the draft as I put it in. The narrow ones seem to me like trying to clean a room by just swinging a duster around in the center of the room. It never makes contact with the walls really.
I just remove the stem after rinsing with water, and if the draft on the stem side is too narrow for the fat end, I just insert the narrow end, up until I see it come out the button, and then spin it as I remove it. Then insert the fat end into the draft on the stummel. I've NEVER had a draft too narrow for the fat end on any of my pipes. Then roll up a paper towel and crank it into the chamber of the pipe to dry it. Then wipe down the pipe really well with a polishing cloth. Voila. Pristine pipe ready to be smoked again, or racked for latter.
