Used franke sink (Wallington)

Hi, I am getting my sink replaced as the old one has a lot of limescale marks. I wasn't able to get rid of them but you may know how to. Please see attached pictures. Tap not included. For the sizes please look up Franke Mythos 1 Bowl Onyx Granite Kitchen Sink MTG 611 LHD.
