We have an area of 4 X 4 aluminum tiles behind the cooktop. I bought some oven cleaner for my mom's caretaker to clean the cooktop grates. She got carried away and sprayed the aluminum tiles too. It was a mottled, blotchy mess when I got here. I managed to get all of it off with a little scouring power and an abrasive pad, but now it looks dull. I know it will never be perfect again, but will aluminum cleaner give it back some shine? I wipe it and a black film comes off on the paper towel. Any way to restore this somewhat to a metal look again with some shine?

I would really appreciate any help! It was a brushed finish before. Thanks!
