The key difference between a rust converter and a rust remover is that one causes rust to separate away from the metal surface while the other converts rust to a stable compound. Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides (rust) into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide, converting them into an adherent black layer that is more resistant to m
