You need to go get these three things:
The Dremel Vera Scrubber (check the clearance @ Home Depot. I found mine there for $29) runs the perfect RPM to polish the plastic without risk of heat damage. After 3-4 passes using Maguire's PastiX, the lenses will be clear. 5-6 passes and it's crystal clear. You can get a bunch of 2" foam and cotton buffing pads on Amazon for $10. I switched out mine every other pass to cut down on possible debris. Once you get it the way you want, spray the UV protectant to keep it looking good for 2-3 years. This not a 15 min quickie….but a true remedy.
