It appears to be a combination of marks and scratches. Tried washing with upholstery cleaner and conditioner. I will try the Magic Eraser Idea and let you know how that worked.what have you tried already? Do you know how you got them? Is it s scratch or a mark? Looks like a mark to me. If you are doing it yourself, you can try the Magic Eraser by Mr.Clean (found at places like W*lmart) or Plexus (not sure if it work).
