Polished aluminum oxidizes slowly, so you'll need to polish every 3-4 weeks to keep them shiny.

In addition, you'll need to use a specific wheel cleaner to remove brake dust, as harsh cleaners can etch or stain the aluminum.

I run billet aluminum on a couple of my cars, and I polish them every 3 weeks, and every 3 months pull them off to polish the back side.

I wouldn't recommend running polished aluminum in the winter time, if they use salt or other chemicals on your roads.

Chrome is, admittedly, easier to care for, but I prefer the polished aluminum look.
