I received a dash cleaner that was recommended by MB. It is part number A 000 986 47 74. It retails at the dealer for around $10. It seems to work fairly well if you use a micrfiber towel to wipe off. I tried it by applying to a rag, then on spots followed by the microfiber towel. It does not create any gloss or objectionable appearance. It had to be ordered from MB. Good luck .
