No worries, I didn't take it as suchI didn't mean to sound terse in my reply previously..
I usually smoke 5-8 bowls a day, often rotating a few pipes per day and warm water rinse the lot every week or so. I put mineral oil on the pipes and stems after warm water cleaning and let them sit a day or so before wiping off the excess oil and buffing with a rag. My Dunhill is the only vulcanite stem that plays nice with this routine. Based on my experience and habits, I won't buy a new pipe unless it has lucite/acrylic stem.
