Despite the corn-ball name, PolyWatch does a good job removing fine surface scratches from different types of plastics. I've used it to remove scratches from both my car and motorcycle instrument cluster lenses. It's marketed as a acrylic watch crystal polish and as such, it's sold in small 5gram tubes for about $8.00. I've only seen it available for sale on the internet, but you could probably see if a local jewelry store stocks it.

I use Plexus plastic cleaner/polish for regular cleaning and protection of headlight lenses and instrument cluster. It leaves a clear polish-able film on the surface. Should only be used on smooth hard plastic surfaces; so don't use it on the satin anti-glare Nav. screen
