What is RUST on Moh's hardness scale? : geology

Short version trying to get rust (iron oxide) off some iron weightlifiting plates. Steel is a 44.5 and iron is a 4. So theoretically, if I used a steel wire brush I would degrade the plates right? But if rust (because it is iron oxide, not just iron) has a lesser hardness could I just use an Iron brush or something?
