The pipe doesn't look dirty enough to reak badly, it may be your just not use to a tobacco sent.
The shank is a bit dirty but, a bristle cleaner should get most of it out. The bowl looks like
someone really reamed it to the wood and may have gone down a bit too deep, it's hard to tell
in a photo but, I would run a cleaner through the shank to the bowl and see if the cleaner
comes in contact with the bottom of the bowl. If not it may need a bit of mud in the bottom.
Depending what brand and type of pipe cleaners your using a standard "Dill" pipe cleaner should go
through the stem, stingers are always a bit of a hassle to get through but, being it's been cut off
it should pass fairly easy.
