We are sorry your glider bench is starting to rust. The most common cause of rust is prolonged exposure to water. Any metal that contains iron, including steel, will bond with the oxygen atoms found in water to form a layer of iron oxide, or rust. Rust will increase and speed up the corrosion process, so upkeep is important. We would be happy to help with replacement parts and provide some rust preventive instructions for the future.
