Aluminum Cleaner from BoatLife features a highly specialized low-micron formula designed for use on only bare or anodized aluminum, removing oxidation and stains while it polishes and brightens the metal. The cleaner is easy to apply. After any surface dirt is washed away with soap and water, dry the metal and then work the paste onto the surface. Buff it out to restore the luster. $25.45 per 16-ounce jar; boatlife.com
