Hi, Anyone come across a problem with the chrome window surround trims discolouring. I have a Superb (May 2010) Elegance estate, and noticed all the metalwork surrounding the windows has discoloured, with what appears to be a hazy white milky sort of colour. Tried cleaning it with a very light Meguiars scratch polish on only one small piece with no effect whatsoever. Any information/ideas gratefully received. Thanks. (pic attached)
