Aluminium Door Mirrors

[Odds]

Apologies if this has been asked before.

I recently acquired an Audi that has aluminium door mirrors, and wondering if there is anything special I need to do for cleaning, maintenance or protection ? Will the polishes and waxes I normally use be suitable, or can you recommend something specific ?

Thanks

Assuming they're lacquered just wax 'em
