I have a used, unsmoked by me, adjustomatic. I was wondering what kind of routine maintenance should be done. The unremovable metal stinger thingy is throwing me off a little. Also there appears to be a little rust, any ideas on how to clean it up a little? Finally, I just picked up a reamer from a local head shop. The owner who sold it to me asked me what it was :crazy: I've only used dull knife blades and such to ream my pipes, and don't know if I even plan on opening this. Was just curious because I never knew Dr. Grabow made reamers. Could I have found a rare find, or just wasted $4.
