Try 0000 steel wool. I have also read of people wet sanding chrome with good results (1500-2000 grit, then buff). I would practice on a spare first, though. For any rust, use pure lemon juice and a toothbrush. When you get it clean with no visible rust, wax it, and keep it waxed. _________________ Plate of shrimp |

Those "ugly" rectangles you are trying to "remove" are the parts of the bumper that are in better condition. The bumper was protected by the stickers.
If you want the rectangles to not be visible, focus your polishing on the areas outside the rectangles. _________________ "The new Volkswagen 1303. We've made so many improvements, they're beginning to show." |

Don't use steel whool unless you have a very good buffer. You will see microscopic lines/scratches in the chrome in the sun. Only use steal whool if the chrome is in real bad shape. A good fine abrasive is tooth paste and a rag then polish the crap out of it. I have also used cola to get microscopic blemishes off. The acid in the coke is a mild abrasive and eats the microscopic blemishes. Lemon juice is also good as Tr0utman said but a little expensive. Cheap cola is easy toi find also. _________________ "Sic Vic Pacem, Para bellum - Pray for peace, prepare for war."

When I first read your title, my immediate thought was a bumper full of rusty pock marks, of which there is little to no hope for
Upon seeing the pictures though, I call what you have there "ghosts"
Same thing can happen to window glass. The past is haunting that bumper blade!

I agree, the sticker has kept off the natural effects of sun, acid rain and road dust from aging the chrome.
I honestly don't see any amount of cleaning, polishing or spritzing with anything removing it entirely.
There was a sticker on the donor blade that's on my car now, a little 2" square from an old college parking pass. Took the sticker off, cleaned the polished the blade with XXX Chrome Cleaner and 0000 Steel wool when I installed the bumper a few years ago. Now that it has weathered awhile you can hardly notice it, but it's still there.
Keep the bumper cleaned and polished of course.
Exposing to the sun and weather a few years will even it out a little.
Or, put a bigger, better sticker over it _________________ -Bruce
