How often do I have to paint my handrail to help prevent against rusting?

As a home owner you are aware that all outdoor items will require maintenance. After your handrail has been installed, you may notice minimal surface rust in the joints or seams. To maintain the ironwork it is best to clean the rust off. Then touch up the area with spray paint or a small brush, it is best to use an oil base enamel paint. To help prevent against rust it is best not to salt around the ironwork and visually inspect the ironwork once a year. Paint and touch up as needed.
