Rust remover is a chemical solution designed to dissolve and eliminate rust from metal surfaces. It works by breaking down the iron oxide (rust) through acidic or alkaline reactions. Common types include phosphoric acid-based removers, which chemically convert rust into a water-soluble compound that can be rinsed away. Other formulations may contain citric acid or oxalic acid. Industries such as automotive, marine, and manufacturing use rust removers to restore metal components, machinery, and tools. These solutions vary in strength and application method, from brushing or soaking to spray application, depending on the severity of rust and the type of metal being treated.
