i own a 2008 ls460 with 23000 miles the chrome besel around my exhaust is turning black does anybody have this problem thank you al neuman

common problem, just get some 0000 steel wool and some degreaser like simple green or other and it will come off, then use some never dull or other stainless steel or metal polish to help keep it clean. Carbon will build up on it again, just keep it clean with your washes and you should be good to go.

I wipe it off with a rag then hit it with a little chrome polish. Works like a acharm

I had the same issue more info here how I cleaned mine.
