I usually wash them clean so that there's no dust or dirt left, then use Meguiar's Plastic Polish with a terry or microfiber cloth to finish off. I'd be curious to hear if anyone does something that works better..

furious, I think the Meguiars is the way to go...very important to use cloth which will be soft and non-marring...wipe off before it dries......start with a clean windscreen..
