Any gloss plastic with slight undeep scuff marks can be polished to new. Examples are gaming consoles, monitor bases and bezels and other gloss plastics. I suspect it also works on turntable plastic covers.
You use toothpaste and rub in circles polishing with soft cloth. Rub out using clean cloth. Repeat polish till shiny like a mirror again. Brasso also works but toothpaste is more coarse.
I am sure one can sand if deeper scratches but this works for fine scuffs.
