Step 4 · Execute Mechanical Rust Removal

Employ tools like wire brushes (manual or drill attachments), sandpaper (various grits, starting coarse and moving to fine), steel wool, or abrasive pads. For heavily rusted items, a grinder with a wire wheel or flap disc might be necessary. Work systematically across the rusted areas, applying consistent pressure. The goal is to abrade the rust down to clean metal.
