My pipes always smell like the last thing I smoked in them. The smell will fade over time, but they will always smell like they've been smoked. Personally, I have a rotation of 8 pipes, that I routinely smoke. My cobs, I just smoke whatever I want in them, while my briars are smoked with specific blends in mind, ie.....aro's, va's..flakes, etc..... I recommend picking up a few cobs to try and it's a very inexpensive way, to increase the number of pipes in your rotation. I never smoke the same pipe two days in a row. I like them to get a little rest.
