One of my custombilts had that perfume scent in it for so many smokes. It's a decently large chamber so I was trying to make it an English. I thought that the Latakia would destory the scne but it almost seemed to grow stronger with every bowl. The pipe would never get rid of that flavor. I ended up making it a BurPer/VaPer pipe and the scent disappeared. Burley Flake #3, Limerick and Solani 633 showed that ghost who wears the daddy pants.
There is something that I have always wanted to try; can't because I don't have an over here in Japan. GL Pease has used activated charcoal pellets and an oven to remove ghosts. Given the abosorption properties of charcoal, I feel this might be a very effective
ghost buster :p
