The grille on my truck is dull I guess its oxidized, do any of you guys know any cleaner or anything to take this off?

i have the same question. i have yet to try this but someone told me to use wd-40 and steel wool. now like i said i never tried it yet but hey its worth a shot.

I found that you use Mothers Mag and Aluminum Polish first then go back over it with chrome polish. It worked great for me. It got rid of all that hazy Oxidized look.
