Mequires makes a plastic cleaner and a plastic polish (they
also make a combined "cleaner / polish") that you can use for
the job. I originally used the stuff to clean /remove
scratches from motorcycle face shields. But since then,
I've used them for everything from back windows on convertible
tops to watch "crystals" and they work very well. Use the
cleaner (mildly abrasive) to remove scratches and dull spots,
then use the polish to shine it up.
