i've had good luck with pressure washing and dressing them with mop n glo. works well on the bed liner as well

I've had my 2012 for a couple months and it was driving me crazy. I hand washed them and then on a whim tried 303 Products on it. It brought it back to black instead of gray and it is not slipper at all.
Also applied this to bed rails and made them more black and it is a great protectant. It's not shiny either.
