All of the suggestions above will achieve good results, although some will require more "elbow grease" than others. Adding a couple more ideas- 3M makes a polish for this application and any large plastics supplier has polishing rouge and buffing wheels for a drill.
If your cover only has the micro scratches, a cream with very light abrasives like the "Mother's" suggestion in the previous post will probably work with the least amount of time/effort/money.
