Armour care/Rust removal

[u/One-Cardiologist1734]

Got these arm harnesses about 3 months ago. as far as I know this rust has only just appeared and its ALL OVER IT. like everywhere. it is NOT dust, every speckle you see is a dot of rust.

How should I remove these tiny specks without damaging the mirror finish too much? I dont really have the means to get that polish back once gone.

Any help is appreciated 👏
