I would first try Lawrence's recommendation. Failing that, try soaking the stem for a day or so with a pipe
cleaner drenched in a thick solution of baking soda and water; or maybe just submerge the whole stem in it.
You might also considerOxiclean, which is purported to be safe for jewelry, so it shouldn't harm the metal stem.
I'm with docrx. I'm betting it is a Lakeland ghost. A good alcohol scrub after a good reaming and a serious burley routine should help.
I swear Lakeland is one tobacco that must be an aquired taste because I just can't do it. :puffpipe:
Is it Lakeland soapy or latakia soapy? To me Lakeland has a floral flavor that makes me think soap, but also perfume. Latakia blends have a slighly bitter taste that I associate more with just a basic, plain soap flavor.
