I've searched a few times on the threads, and get mixed results for answers... easier to just post my question directly. With regards to estate pipes, I see lots of talk about cleaning pipes... salt and alcohol, PC and everclear, etc. Even some talk about buffing the outside of the bowl, etc. But does anyone do anything special to the bit? (Hope that's the right terminology...) In this day and age of communicable diseases and such, is it pertinent to clean, or even sterilize, the bit of a used pipe before using it yourself? And if so, how do you go about doing so without ruining the integrity of the pipe or the flavor of future smokes?
