File smooth, and then use an oxy-hydrogen torch with a soft flame. This
will give an instant flame polished edge. See your local plastic
supplier if you're not equipped to do this solo.

Right on, Rip. This is the slickest, easiest, most professional way to get
clean, clear edges on Lexan and Plexiglas. If you are really quick with
the torch, you can de-burr drilled holes this way too.

And -- if you are NOT quick with the torch? It is safer to use the
filing/ sanding/polishing technique.
