So, this isn't mine, but here's a pic to give for elaboration: http://www.grasscity.co.uk/img/products/glass_spoon_pipe_clear_bead_f.jpg So at the bottom of the bowl area, some black crap gets stuck at the bottom after a while. I cleaned my pipe THREE times thoroughly with Isopropyl alcohol, and go the job done except for that stuff at the bottom. I can't unscrew it or anything, the only way to reach it is through the main hole or choke. Anybody have any ideas? It's not a big deal, I'd just like my pipe to look cleaner.
Did you mix salt in with the alcohol while you were cleaning it? If not try using coarse salt and alcohol with the piece and a ziploc bag and shake thouroghly. That should help gettin the resin out.
