Rust Removal By Electrolysis - VintageMachinery

Since red rust (ferrous oxide) formation is an electrochemical process (oxidation), all we need to do is reverse this process. During oxidation, electrons are given up by iron and combine with oxygen. The result is ferric oxide (black rust). When ferric oxide oxidizes, ferrous oxide is formed (red rust).
