You never use steel wool on chrome!!! In such cases where I have overspray or yellow rust, instead of steel wool, get a piece of aluminum foil from the kitchen and fold it into a small square. Apply lacquer thinner or chrome polish to the square and scrub your chrome with it. The aluminum foil is stiffer than a rag, but softer than steel so it won't scratch. I've made some really ragged out chrome look good again with that trick..
