Your steel porch railings are under attack every hour of every day. As kryptonite turns the Man of Steel (Superman) into a quivering mass, rust turns steel railings into a grungy mess. But, like the Man of Steel, you can come to the rescue. Use a wire brush or wire wheel on a drill to get down to bare metal; and be sure to get it all. Rust in tight corners can be dissolved with a thick coat of chemical rust remover. Let it sit for half an hour, then rinse well. Once the rust is gone, paint the railings with a zinc-oxide- or red-oxide metal primer. This will discourage future rust attacks. Finish the job with a coat of good high-gloss, oil-base enamel paint. Faster than a speeding bullet you will have railings stronger than a locomotive that are able to withstand rust for years to come. And that's the On The House tip for today.
