Regarding discoloration, as others have pointed out all that needs be done is removing the mats and rubbing with a soapy sponge and they look factory-fresh. Truth be told, with my kids and their activities, I remove the carpeted mats and go with the all-weather mats all year long. They look great and they are very protective, the new F30 design even moreso.
