How to Protect Wrought Iron
Wrought iron has been used for centuries for fencing, gates and outdoor furniture because of its durability and fireproof nature. It is also a great outdoor choice because it is impervious to insects, strong and resistant to rot. The only thing that iron can not stand up against is rust. Simple semi-annual maintenance will keep your wrought iron from suffering the ravages of rust, but it should be re-coated every five years.
Periodically wash the wrought iron with warm, soapy water. Rinse with hose water.
Scrape off any signs of rust with a steel-bristled brush or sandpaper. Wipe clean.
Prime and paint any nicks or dings with a thin coat of oil-based metal paint. Dry thoroughly between coats.
Protect the finish with automotive wax on non-textured wrought iron. On textured iron, use mineral oil or baby oil to protect.
Scrub the wrought iron with a steel-bristled brush to loosen any paint and rust.
File down any rough edges with either 80-grit sandpaper or a metal file.
Spray all metal surfaces with a coat of phosphoric acid to neutralize. This will convert any specks of rust remaining to a crust, and will prohibit its spread.
Brush away any loose paint or flakes. Apply a heavy coat of primer with a bristle brush.
Paint with an oil-based metal paint, using a chip brush to apply paint from the top of the piece down.
