I had some black stains on the carpet that Newell puts on the inside of interior cabinets.  Since the stains had been there since I purchased the coach in 2010, I was not optimistic of finding any thing that would remove them.  I tried Folex instant carpet spot remover on the light tan carpet.  All stains now gone.  I followed the directions to soak the area, agitate area with fingertips and blot dry.  I suggest using a white cloth for blotting.
