Plastic polish?

Getting ready to clean up the gauges on my Swinger. I took the cluster apart and dusted it all off. But I guess with the years of rubbing the dust into the plastic it is scratched up. not deep just from using what the PO's had in the shop for rags. Is there something out there to get the scuffs out of it. I would like to be able to see the gauges once I get it back together. Thanks.
