Plain Pledge is good, if it is still available. Avoid the lemon scented stuff...oils may cloud clear plastic.
Any one of the reputable canopy or motorcycle visor cleaners should be good.
I've been using plexus and lemon pledge for my motorcycle visors and windshields for about a decade. I see almost no difference between the two, and no negative effect on some expensive and valuable (to me) clear plastics.
I find that el-cheapo generic lemon pledge works even better for dead bugs/ plastics overall, because it is the same as pledge, just watered down a little.
Plexus/Pledge/cheapo pledge + good microfiber towel = clean plastic
