This is the coolest rust remover ever!

Evapo-Rust is an organic rust remover that removes rust without affecting the remaining steel by using a chelating agent. Evapo-Rust is very safe and has no disposal problems.

You can find it in several sizes at andahammer.com along with some LED flashlights and an amazing bargain binocular.

 

Here is a very very rusty M14 barrel that has been dipped in Evapo-Rust overnight.
