I read a post (which I can't find) about cleaning the willow floor mats. I tried it and it works very well! It would work on all the colors infiniti has available.
Heres how:

Use the washing machine on the "delicate or knit" cycle. Use a non bleaching or safe bleach detergent. You won't need much. Add the detergent and OXYCLEAN (about three little scoops) to the wash before adding the mats. The Oxyclean is VERY important. Dry on a line or use the air fluff for about 30 minutes. Then use the regular dry for about 20 minutes or until dry. You'll need to check as the drying progresses to make sure the mat is okay. The mats will become very pliable as they dry so you may want to make an adjustment or two. You'll have to try the system to determine which drying times work best.

Double Mat Chango's.....My eventual solution for my willow mats was to clean em up, scotch guard em...use them only in our desert environments out here in So Cal. I have Euro-grey mats for around town in the coastal areas, you know greasy parking lots, etc.,,,,and they work well, The euro-grey compliments the greyish trim in our willow leather coupes.
