Anyone have any information on interior detailing / cleanup for the RLs. What to use for leather cleaning, vs. what to use for other plastic parts. It appears that the previous owner had kids in the car who did nothing but munching. I removed the back seat, and found several liquid spots -- juice/milk/u-name-it kind of crap. The interior, otherwise looks very clean; it is when I get to the minute corners of items, say the cup holders, that I find cookie crumbs, etc.
