Stains on the surface can in most cases be removed with a so-called Nano-sponge/magic sponge. This applies to both marble and composite.
Limescale deposits can be reduced by cleaning the basin frequently. If there are scratches in the marble, you can polish the sink with a fine polish and finish the basin with wax, for example car wax.
If there are scratches and small nicks in a composite sink, it can be sanded with fine sandpaper, grade 1000 or a sanding sponge. If the treated area appears shiny after sanding, it can be sanded with grade 800, followed by grade 600 and finally finish with a soft, dry cloth. Always start with grade 1000.
