I dive with the same few dive ops (most are "valet") and they all know to leave my atomic reg alone. I did have one or two crew dunk my whole reg when I first started diving with these ops. At my first service - after only a year due to some creep - there was corrosion in the first stage, so I assume it was the dunking. I'm pretty insistent now. I dunk my reg (and bcd) in the rinse tank with the gas tank attached so it's under pressure (and now some of the crew will do it that way for me). If I soak the reg at home, which I do every few dives or if I won't be diving for a week or two, I attach a pony and soak under pressure. I hang it up to dry before storing it. It's a small PITA but if it keeps the water out I'm ok with it. And I need to hook the reg up to air to test the IP before each dive anyway.
