Re: Aluminum Restoration
Grill finish is usually sealed with some form of an iodized finish. However, if you truly want to clean it, then I would use a steel wool, as suggested, but then I would follow with a 2500 grit wet-N-dry sandpaper, using WD-40 as a lubricant to keep the paper from loading up. After that I would use Mothers Aluminum polish to start and then finish with the Mothers Billet Pollish for a mirror finish.
If it is hard cleaning, then look on the web for what is called "Razor Buffs" and get some of them to use on a die grinder and get some green and white rouge polishing sticks from your local truck stop. They use it to clean the semi truck tanks and wheels. The razor buff will clean the metal and you do not have to put any real pressure on it to do the work. Follow up with a small amount of billet pollish to clean and then seal the metal with a metal sealer, like Wizards sells. That will keep the water spots off of it.
