Machine parts and components are usually made from metal or steel. If you aren’t aware, steel and metal surfaces are prone to corrosion such as rust. Rust forms when the object is left wet and unwiped which exposes the surface to water, air and moisture. When that happens, hydrogen and oxygen atoms combine to form rustic surface that will slowly consume the metal surface. Rust forms which can be very damaging. That is why, you need to consider chrome plating to protect the surface against rust and corrosion.
