Rust is the bane of many metallic tools, surfaces, and machines. Rust is an iron oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture. Given sufficient time, oxygen, and water, any iron mass will eventually convert entirely to rust and disintegrate.
With iron being so common in industrial workplaces, it is clear why the battle with rust is one that must be handled with care. A simple preventative measure to reduce rust is to paint as much of the iron you are working with, if possible, with a protective layer of paint. A machine body, for example, painted with protective coating, can keep the iron under a shield that protects it from air and moisture. This is not feasible for all iron parts, so having a good anti-rust spray is another necessary tool.
Anti-rust spray is a common product used to maintain rust-free tools and machines. They come in various types and solutions, but the concept is the same: spray targeted areas of exposed metal, and the anti-rust elements will slow down or reverse the rusting process. If rust has already appeared, rust-removing sprays are available. They are designed to eat away at the rust itself, and leave the metal in better condition than it began.
In worse case scenarios, rust will eat through the base metal, which flakes away, leaving pockets of bubbles. At this point, you can replace the affected area or you can cut out the rotten areas and weld patches to replace them. The oxidizing process will always be a consistent issue with products made with iron. The only way to stop rust from happening is to constantly maintain the health and wellbeing of the metal. Regular cleaning, anti-rust preventative measures, rust removal sprays and procedures, and replacement parts should all be part of the regular routine to maintain rust-free metals.
