How to clean / polish instruments cluster lens?

kursplat said
i'd like to polish out the minor scratches in my clusters lenses. any suggestions what to use or methods? or talk me out of it. they're in great shape, but while it's apart, why not?

I use Meguires polish and a soft cloth by hand and it works good.
Replaced my speedo lens with lexan next time I had it out.
