Cleaning ebony vinyl surfaces?

What is the best thing to use to clean or restore the black(ebony)
surfaces(doors and dash) on my 2005 C6? The manual says to use mild soap and
water and not to use anything with silicone. After soap and water it still
looks sort of dull and drab.
Thanks in advance!

Are you saying that you WANT glaring reflections off the dash in the
windshield?
