I have the new xbox 360 and I have a new laptop I brought and also a HD TV. All were expensive and they come in a slick black gloss finish looking very nice. They get dusty very easily and I read the instructions from all 3 products to see the best way to clean them. I followed them but now when I look at them all the black gloss finish has been scrated off and theres miny scratces round them all especially when the light shines. I followed all the cleaning instructions properly and was very careful. Should this be happening?
