How to Clean Rust Off of Keys
- 1). Wipe off any dirt or debris covering the rusted keys. Vinegar works better when it can make direct contact with the rust.
- 2). Simmer enough vinegar to cover the keys in a saucepan. Don't put the keys into the saucepan, though.
- 3). Pour the vinegar into a bowl. Add the keys. Allow the keys to soak for 30 minutes. If the rust layer is thick, soak for another 30 minutes.
- 4). Take out the keys. Use a toothbrush to scrub off the rust. If rust remains, soak for another hour. The acid in the vinegar removes rust.
- 5). Wipe off all residue with a rag. Don't worry--the vinegar smell disappears after a little while.
