There were brown spots on the interior passenger side roof. When I sprayed window cleaner on it and wiped off with dry cloth, came right off. Waiting to see if it comes back.. it wasn't wet as far as i know. Was going to have car wash place try and get it off, but they wouldn't touch it afraid mite put a tear in materiel..Am going to keep a check on it to see if it comes back.

Will keep you informed. Just wondering weather any one else has this proublem
