How to Remove Rust from Car Keys?

[MacPhoebe]

Methods for removing rust from car keys: 1. If there is a significant amount of rust on the key, you can use steel wool to scrub it while wiping away the rust with water. After scrubbing, dry it with a towel or soak it in vinegar before drying. 2. If there is only a small amount of rust, soak the key in vinegar for about 40 minutes to loosen the rust. Ensure the vinegar fully covers the key. After soaking, dry the key and apply a layer of engine oil. 3. Use sandpaper to scrub the rust off, which can also make the key smoother. Place the key between two layers of sandpaper and rub it back and forth. 4. You can purchase a rust remover, spray it on the key, and then wipe it clean.
