Can I preserve this binder clip? - Leminal Space

I have this cheap binder clip from Amazon, which wasn’t actually cheap imo, but whatever. I like the cat. I’d like to keep using it, but the “brass” paint is rubbing off, and it smells like metal. I think it reacts with the oils in my hands or something. I’ve only been using it for a few weeks. Is there something I can do to keep it looking nice and perhaps prevent it from wearing down so quickly? [https://leminal.space/pictrs/image/40f1aca8-c857-429c-833c-66c0da0650f9.jpeg]
