Cleaning up old nuts and bolts ?

[68gmsee]

Does anyone know of a good way to clean the rust and grime off? I'd like to reuse the ones that are in good condition in my old trucks and others that I've accumulated over the years.

I've used petroleum jelly and other rust removers before but these won't protect the metal once the rust is gone. I'm hoping there is something else out there that works better.
