How does Evapo-Rust Work?
Unlike some products that use acids to remove rust, Evapo-Rust uses a chemical process called chelation to selectively remove rust. Chelation is a process where a large synthetic molecule forms a bond with metals and holds them in a solution. The active ingredient in Evapo-Rust bonds to rust while leaving surrounding materials unharmed. the P.S. more rust the longer you soak. never use on real real rusted object yet. But I well try some time and leave the result.
