How can I remove rust on wrought iron fencing?

Rich Wilson
by Rich Wilson

I moved into a 1.5 acre property surrounded by this rusted fencing. I have experimented with sanding, rust removers/neutralizers and have even considered sandblasting, but have yet to zero in on the the most efficient option to get paint on these without getting the rust back within the year. Have I missed any solvents or other ideas that may make this rust removal any quicker? Thanks for any thoughts!

There are close to 100 of these!

    Where are you located? The fact that the rust is recurring so rapidly makes me question what environmental forces are acting upon your wrought iron (excessive rains/humidity/snow ?). Thorough sand blasting or sanding to bare metal, sufficently priming the railing and coating completely with several coats of paint designed for exterior wrought iron would survive longer in zone 6 than has been your case.

    Your photo appears to be of a railing in a somewhat protected area.

      I am located in the North L.A desert so it is usually dry and windy. The railing photo is from a balcony, but the rest of the fencing surrounds the perimeter of the property. I really do not know how long it will take for the rust to return as I inherited this problem, but if painting over the rust would work, I may have been overthinking this!

    I had a rusted fireplace screen. Took it to a place that does sand blasting - they used a low pressure machine and it came out great!

    There are products available to stabilize rust. As I remember, the stuff is painted over the rust which turns black as it neutralizes. So after the rusty areas are treated you would want to improve and protect all the fencing by painting with Rustoleum.

    Hi, Rich,

    Your locale will definitely increase the rate of wear on your railings, due to windborne particles. Treating the iron with a rust inhibitor prior to painting would save you the expense of sandblasting, although I'm not sure what it would do in terms of extending the paint's life. You might contact a local wrought iron manufacturing company to see if it's worth coating the paint with a clearcoat sealer, given your environmental exposure issues.

    Just paint it with rustoleum!
