Muriatic acid does wonders ! As you can see a few post above the rust
I'm sure you know this but thought it worth mentioning. Be sure to cook it in hot water and baking soda to kill the acid, otherwise it will continue to rust away. The hot water expands the metal opening the pores so the soda can get inside where the acid is hiding.
FYI for future use, for a better way to clean up small metal parts refer to Michael Faraday's theory of electrolysis. Here are some cast iron grates I restored using that method. My rectifier outputs 48 volts @ 27 amps so the process goes pretty quick. You can use something much smaller, it just takes a little longer. No need to deal with acid and the problems it brings.
