What to use on swivel racks

[Mcdonas]

Any suggestions on what to use on my swivel racks. They need polishing but not sure to use an aluminum polish or like a chrome? 2014 Moomba Mojo.

Thanks for the suggestion

On the chrome I just use regular chrome polish, on the Alluminum I don't use anything. Only the fingers with rubber pads are alluminum on mine.
