There's several products out there for removing rust. I would like to see what others have used to see before and after results.
For smaller parts that I can fit in a coffee can/bucket I have had good success with Evapo-Rust. The hardware shown is off my old dirt bike that was in a damp garage that I soaked over night in the Evapo-Rust.

I did need to paint/protect the parts after the chemical treatment or they would rust up pretty quickly.
I am curious on other products for larger parts like the Rusty 911 that Chuck mentioned in another thread.
