Reviving Anodized Alum Trim Back 2 Bright?

[bluesky]

For the early 70's bright Anodized Aluminum Trim (door frames & trim and Qtr window frames), is it possible to be brought back to bright?

If this finish has got a patina on it over the years, is there a way to revive it?....like using Never-Dull, polish, etc? No pits or scratches....just a dull patina.

Or does it need to be reanodized?
