I have cleaned them once since I purchased them. You can BARELY tell when they are dirty. You have to pay close attention. I have had them for months now and they haven't lost any color what so ever. My picture does no justice. It's a hell of a purchase. Lloyd Mats are one of the best out there as well.
I have admit these guys like seibon and vis really do a good job when it comes to fitment. Its indve like you get what you pay for ya know. No issues here. Iv heard of some having issues but they took it back and sent another one.
