Ok guys, I need some help. What do you use to remove rust from chrome? In the states, we have some stuff called Naval Jelly. What's good here? I'll be stopping by the auto parts store on my way home, so a quick response is appreciated.

Also, if anyone is feeling charitable, I need a usable set of square taper cranks. They're going on my folder project, so nothing fancy is needed, as I'll only be using the big ring.
