- 1). Use your fine-grit sandpaper (120-160 grit) to begin stripping away the rust and/or paint on your wrought iron. Be sure to sand the entire area, removing all layers of paint and corrosion (See Ref. 2). You will want to sand all the way down to the metal in order to ensure you've removed any and all signs of rust. Any rust that's accidentally left behind will eventually spread and find its way to the surface once again. If necessary, use 80-grit sandpaper to remove heavy layers of rust.
- 2). Rub the wrought iron with some steel wool after you've finished sanding. The steel wool will essentially buff the iron, removing any small bits of paint or rust. When you're finished, you should be left with wrought iron that has regained its original appearance.
- 3). Apply rust inhibitor to the wrought iron. You can purchase a spray can of rust inhibitor at any hardware store. The rust inhibitor will basically act as a primer for your paint and seal the iron against moisture. This is important, as exposure to moisture is the main cause of corrosion.
- 4). Paint the wrought iron with the enamel paint of your choice. Apply at least one coat over the entire surface of the wrought iron. Once again, this will provide the necessary barrier against moisture and rust.
