there was a discusison on here previously about squirting acid into a keyway and opening the lock. I just happened to have a bottle of mild acid and a lock this weekend. it was the lock out of a schlage doorknob. I just took the whole thing intact and submersed it fully in acid. I thought the pins on those were brass? they should have dissolved, instead they just got shiny. the top plate did pop off in the acid and the springs came out, and didn't dissolve. the hull of the lock did infact dissolve. that's what caused the top to pop off. left overnight, there was nothing left of the hull at all. just the cylinder that containes the keyway. it's also really shiny now though.
