what's the best way to remove haze from the plastic lens of a speedometer? Lens looks clear and scratch free when wet.

Other good suggestions have been offered here.  If you do try any of these, try first on an area of the lens that doesn't really matter.  Just in case the result is less than satisfactory.

To do a good job, you probably should look into buying an acrylic plastic polishing kit. They usually contain wet or dry sandpaper in grits from 1500 to 4000 and then a couple of buffing compounds for the final polish.
You can get them at most paint and body parts supply houses and some autoparts dealers.
Look on-line for "acrylic plastic polishing kits"

Plain old toothpaste works as a great polishing agent.
Polish it with some metal polish like "Brasso" or "Duraglit"

You either polish it or you apply a clear coating. Think about spray-laquer, think about buffing it with an electric drill. Also think about replacing it with glass (possibly the most difficult)
