This has already been answered for sure. I have only five RM2s, four Brass and one Chrome. I usually boil them once a month or so. And, yes, they are "married." I set a small tea strainer in boiling water and boil each RM2 individually and then set them, base and cap together, to dry on paper towel. I imagine someone like Trunker, 11 RM2s, last I heard, has to be especially careful to keep them "married." Oh, and yeah, about half the time I'm rewicking cotton, after dryburn, I run cap, with DT still attached, under hot water, blow out, and then finish with paper towel inside to get gunk out. I do only one at a time. Keeps life simple.
