The problem with the metal items recovering is one of flavor. Change it to the rust monster spitting out a goo that slowly corrodes metal over time -- 10 minutes, for instance -- but which can be wiped/washed off out of combat (or by sacrificing a standard action), and it's all good.
Heck, if you changed it to let players take a standard action to reset an item, you could drop the corrosion time quite a bit, since the metal folks would be greatly impacted or face a very real chance of losing their items, which is the point of the rust monster.
For what it's worth, I do hope the rust monster is revised in 4E. While I have an enormous amount of 1E nostalgia, some sacred cows need another look. (I don't mind that the catoblepas is both no longer a core monster nor has its over the top death powers now, for instance.)
