But when you say you do an extra swab near the area of the bit, what exactly do you mean? So in a live smoke, in my experience once you insert the pipe cleaner in the bit, if it picks up any gunk, as you extract the cleaner, the gunk will concertina in the inside of the mouthpiece. It seems to me that any extra swabs would run into the same danger, and the only way to avoid this danger is to remove the stem and pull the cleaner straight through. But then of course if we do this on a regular basis we run into the dangers of the tenon mortise not fitting. It's a quandary, but I may have to start removing the stem and fish for the black gold that way, I never, ever, wnat that dottle near my mouth again. It's Satan's shit lol
