i use stuff called goof-off that's a solvent, much like lighter fluid. i soak a bristle pipe cleaner in it and the jam it everywhere. plus you can put like 6 pipe cleaners together and shove em all in and everywehre to get it all. but really just put some lighter fluid in the pipe and cover the bowl, carb, and mouthpiece and shake well. then run water into the mouthpiece for like 10 minutes to get all the chemicals out then smoke
