Oh sorry, I just read the title of the thread and thought you wanted someone to come over for a few hours work.
Do you mean cleaning the exterior of the bowl and stem or interior?
Exterior; sometimes you can get by with a cotton cloth, some spit, and a lot of elbow grease,.....and sometimes you gotta get out the 0000 steel wool.
Interior; sometimes, depending on the ghosts involved, just a reaming and alcohol wash. If it's pretty crappy you might end up sanding down to the wood and starting over, sweetening with Kosher salt and Everclear, filling holes with pipe-mud and painting with a mix of sour-cream/powdered-charcoal/buttermilk.
