To clean Rally Armor mud flaps, use mild soap and water with a soft cloth or sponge -avoid harsh chemicals or abrasive tools and or direct pressure washing of decorated areas.
Much like a tire or other piece of trim on the vehicle, UR mud flaps naturally matte over time. For a desired glossy or wet look, you can apply a plastic or rubber protectant in the same manner
Avoid direct pressure washing, wire/scouring brushes, bleach, strong degreasers or solvent-based cleaners - they can degrade decoration or logos on the mud flap.
