I'm having a devil of a time keeping my linen white interior carpets clean, especially around the foot pedals, driver's side foot rest and door transom. I can shampoo and get the other areas clean with PS21 Total Wash and lots of water, but the area around the foot pedals continues to be grungy. Also, my carpet is beginning to mat up on the door transom and I try to brush out to no avail. Any suggestions for cleaning as well as any clear type carpet protectors that I can use for daily driving, but pull them off for Concours?
