Two issues, if I read it correctly. Cake and pipe smell. I am among the devoted minority who don't build cake. To do this, I scoop out the ashes and wipe out the bowl with a paper towel or napkin after every smoke, plus pipe cleaner and general buffing with a cloth. If you don't build cake, just a thin carbon layer, you don't have to ream. I have pipes almost 40 years old that have done well. The pipe smell thing will probably fade, however, you'd better find out what the school dorm's policy is on smoking. Further, for the future, understand that the world outside is quite fanatical about smoking smells. If you stay in a non-smoking hotel or motel room, and you smoke, you can be hit with a major bill for ridding the room of the smell. Likewise, many hosts don't want you smoking inside their residences, and some even protest outdoor smoking at their homes. So just understand, this is an issue, and be alert to not getting hassled and not offending unknowingly. Offending knowingly is your own lookout.
