A good soul in the Forums membership sent me a stately billiard Meerschaum with light grape motif etchings on the bowl, in a handmade box probably from the original owner. It has an engraved plate with a name! It has some charring on the rim, about like most of my pipes and not objectionable, and graceful light coloration on the bowl which is (I think) lightly waxed. I don't want to mess up the coloring at all, and I don't mind a little charring on the rim ... means it's a good smoker. The screw-in stem needs a clean-up but is not chewed or worn. So here's my plan, and please let me know what's appropriate. I plan to soak the stem in dishwashing liquid, with a little scrubbing with a pipe cleaner, then rinse it off and give it a few pipecleaner swabs with alcohol. The bowl I plan to simply rinse and pipecleaner out and leave as is. My main objective is to do the usual sanitizing and not alter the pipe's patina and look at all. Can I soak the bowl in dishwashing liquid without removing the wax? I like the finish the way it is. Forgive my lack of Meer knowledge. After forty years of pipes (well, on and off) this is my first Meerschaum.
