How to Remove Rust from Car Keys?
2 Answers
You can use vinegar to soak the rust, allowing it to loosen, and then wipe it off with a cloth. The soaking time should be between half an hour to one hour. You can also use a steel wire mesh for scrubbing pots to wet-sand the key, intermittently rinsing off the rust particles with water. Generally, nail clippers come with a nail file. Some keys are cross-shaped and can only be sanded with a file.
Last time my car key got rusty, it gave me a scare. I quickly used a small toothbrush to gently scrub off the surface rust, then sprayed some rust remover like WD-40, waited a few minutes, and wiped it clean. But remember, never spray near the remote buttons to avoid short-circuiting and damaging the chip. After removing rust, it's best to dry the key with a cloth and store it in a small sealed bag or place some desiccant nearby to prevent rusting again. If the rust is too deep and the key keeps getting stuck in the door lock, you might need to get a new key. To save money, you can buy a replacement shell online and install it yourself. Avoid keeping keys in damp pockets, as sweat can also cause rust. If you don't pay attention to these small things, you might end up embarrassed when you can't open the car door at a critical moment. Regularly take out your keys to wipe off dust and moisture.
