Rust is a natural process that begins when metallic surfaces are exposed to moisture and oxygen. If you need to clean rust and paint off of metal stairs, you're in luck, as metallic surfaces are durable enough to withstand some of the more aggressive removal techniques. Still, use caution, or you could end up suffering unforeseen injuries. In addition, protect the stairs from future rust outbreaks, or you will find yourself repeating the removal process, over and over.
