Evapo-Rust ($6.99) removes rust quickly and easily. Immerse the affected metal in the solution for about 10 minutes for light rust or as long as overnight for heavy rust. Once the rust is gone, you rinse the piece and allow it to air-dry. Evapo-Rust can be sprayed on steel to prevent rust, and it will not damage plastics or clothing.
