What Removes Rust From Metal?

There are several products that remove rust from metal by using either phosphoric or hydrochloric acid to dissolve it. These solutions typically involve soaking time for maximum effectiveness. There are also nontoxic solutions that use an acid-free process to take away rust, relying on chelation to remove the iron.

In addition to chemical rust removal methods, a grinder or sander removes rust with only some physical effort and the correct power tools. Another method of handling rust on metal surfaces is using a spray that stops the rust and primes the surface; this method leaves a rough appearance to the metal.
