I soak my doubles hoser (RAM and DAAM's in warm water with some of Bryans regulator cleaner. Because it dilutes at such a good ratio, little is needed. After about a three hour soak, I rinse everything off, let it dry, and then back on to my peg board where it hangs with my other Dh regs awaiting a new adventure.
Get the reg cleaner, it is perhaps the single best investment if you dive salt water or murky fresh water. No diver should be without it
