If I thoroughly clean a pipe that was in a really bad way, I let it sit for a longer time than usual. I had two 80s Savs that smelled and tasted horrible during smoking even after the cleaning. Let them sit for a couple of months and when I picked them up again they were good to go. Sometimes it helps, but this is purely anecdotal.
The smell isn't going away completely on its own though; you should feel a difference after you smoke a pipe a couple of times yourself to get rid of it.
