removing aluminum anodizing

anyone here ever remove the anodizing that is on aluminum trim pieces.

I want to polish up the grill on my 79 truck, and from I can tell, I think the coating on it is anodizing and not clearcoat, correct me if i'm wrong.

I read online where oven cleaner or lye based draino will remove it, then the piece can be polished with aluminum polish to a shine......anyone try this with satisfactory results....

thanks fellas, Jim
