To remove rust stains from plastic, use chemical methods (rust removers, phosphoric acid, hydrochloric acid, oxalic acid) for deep stains or mechanical methods (steel wool, sandpaper, pumice stone, emery cloth) for surface rust. For chemical rust removal, apply solutions to the stain and allow it to work. For mechanical rust removal, scrape or sand the rust away. To remove rust stains using vinegar, soak the affected area in a vinegar solution or apply it directly to the stain and let it sit. Always test the solution in an inconspicuous area first and wear gloves and eye protection for safety.
