Recently I bought this baby, for cheap. Needed little restoration, smokes well, and the stem seems to be .. bone. Any way, cleaning it is a bit problematic, since inserting a pipe cleaner from the shank part towards, what I was hoping to be, the bowl ends up down to that screw cap area in the bottom. I tried inserting a pipe cleaner from the inside of the bowl towards the mortise, but the hole - while not too narrow, won't pass a pipe cleaner from that direction due to the curve. How would you guys go about this? Of course ... there is always bathing the pipe with warm water, but I don't want to do that since it has a number of non removable metal parts, that don't seem rust free.
