Sukie, I laughed out loud when I saw your subject line. I can just picture the ferts running around in a Johnny Cash kind of way singing, "I'm gonna break... I'm gonna break my... I'm gonna break my rusty cage and run..." Anyway, if the rusty bits aren't huge or really bad, I've had good luck with CLR. Of course this stuff is NOT safe for ferrets, but if we're talking the thorough cleaning of a cage, and residue would be cleaned off, I'm sure it would be OK. Something to consider anyway.
