Rust removal is the process of eliminating rust, a reddish-brown corrosion that forms on metal surfaces when they react with moisture and oxygen. Common methods for rust removal include using chemical rust removers, sandblasting, or mechanical tools like wire brushes. These techniques help restore the metal's appearance and prevent further deterioration. After rust removal, it is essential to protect the metal from future rusting. This can be achieved by applying protective coatings, such as paint or rust inhibitors, which create a barrier against moisture. Regular maintenance and inspection can also help keep metal surfaces rust-free and extend their lifespan.
