If you are referring to the DigitalFit liners. DigitalFit liners are made of a different material then the regular WeatherTech mats TPO (ThermoPlastic Olefin). I have had them in 5 cars so far and with regular maintenance they maintain a satin finish. Regular cleaning with a mild APC should do the trick. They do tend to get dull in any spots with frequent scuffing after time but I have found no totally effective way to eliminate this. The regular WeatherTech mats get dried out and dull after time. I would refrain from using to harsh a chemical on then as it will speed up the process of deterioration. I have also had more than a few sets of these mats also so I speak from first hand experience.
Quick tip... Weathertech mats (not the liners) seem to wear out rather quickly at the top of the ribs in high traffic areas. simple fix is to clean well, flip over and run a bead of black silicone into the groves of the high traffic parts of the mat. When the mat wears through the silicon keeps it from completely wearing through. This can be done before or after they wear through as it also forms a pretty tough bond with the mat. I made my first pair last 13 years that way.
