Polishing aluminium truck grill

I have a 1969 ford truck grill and it is made of anodized aluminum. I have tried all kinds of polishes on it to make it shine but it is still dull. Someone told me to clean it with oven cleaner ⇦ on eBay or Amazon [affil link] and then polish it and this works. I was wondering if that will make it tarnish any faster than if I hadn't cleaned it with the oven cleaner?

It will work, but it will also tarnish if you do not keep it waxed or polish it often. The polish has some oils in it that help out.

As to polishing the anodized grill. I have done at least 10 anodized grills on Freightliners. I have found that a product called Aircraft Stripper, or polyurethane stripper remove the anodized coating completely.

I find the best that works for that particular thing is wipe off with gunwash then polish with jeweler's rouge ⇦ on eBay or Amazon [affil link] then finish off with a coat of Autosol ⇦ on eBay or Amazon [affil link] . Use the green bar with the green cutting pad for this ....I have done at least 250 grills a year ...try it may work the best.
