Help with refurbish

I have a simple question that I can not find the answer to. I want to refurbish my first razor. What is the best way to clean up the plastic scales. I just want them cleaned and maybe remove a few shallow scratches and polish them up a bit.

Thanks for the help

Plastic polish is a great option. There are many kinds. Novus makes a few that can be used progressively, or you can use the stuff made to clean headlights (found at auto shops).

Micromesh pads work great

Flitz will clean them up but won't remove the scratches unless they are extremely light. I like it because it is also a pretty good metal polish, like MAAS, so it can take care of multiple jobs.

I start with a Mr. Clean magic eraser followed by MAAS when faced with plastic scales then decide where to go from there based on my results.
