10. Loctite Naval Jelly Rust Dissolver

Best Car Corrosion and Rust Inhibitors

This Naval Jelly Rust Dissolver by Loctite is ideal for when you have rust that’s already taken hold on your metal surfaces. This acts by dissolving the rust at its source, allowing you to quickly and easily remove the remainder. Clean the metal surfaces with coarse sandpaper or a wire brush so as to remove all of the dirt, oil, grease, and loose rusted metal from the target area.

Once your area is prepared for cleaning, apply this Naval Jelly Rust Dissolver to the surface of your rusted metal. In the event it is a painted surface, you’ll need to wipe it off immediately. For rusted chrome surfaces, limit the use to 5 minutes. For all other metal applications, wait 20 to 30 minutes for the rust dissolver to work.

Rinse the rust dissolver off, sand it lightly, and repeat if necessary until your rust problem is no more.
