The black cloth seats in my 17 sport stain very easily. I have used a little interior cleaner to try and get rid of it but it seems to make it worse so I just live with it. The stains look sort of white and circular like water stains and when I tried to clean it the circle just gets larger. I like the material and pattern of these seats but the stains bug me because I'm a bit of a clean freak. Anyone else had this issue? Any suggestions?
