Gentelmen

I have attached a picture of my 560SL star. The grill pices are in the same condition. I would like to know the proper way to restor the color of this star and grill pieces to the original condition. I would also like to know if the chrome star can be removed from the rest of the centerpice. I know it looks gold in the picture but it is chrome.

These pieces apear to have a dark metalic gray color. I was wondering if that was paint and if so what is the color code. The pieces are stained and faded tomarrow I will try washing in the dish washer. Any other ideas?
