It is not possible to remove cloudiness once it happens. I spent many hours with various methods and compounds. Yes the surface can be cleaned but the molecular structure changes causing cloudiness. I can not find new replacements either. Any leads?
Cloudiness is caused by UV, heat, and time. These change the molecular structure throughout the material. 25 years of exposure is a long time considering the technology then and now for manufacturing, but even todays plastic lenses cloud up. Surface imperfection only can be resolved.
You can buy plastic compound/ polish in a small plastic bottle. I did a completely fogged over rear convertible top window (you couldnt see out of it) in my T/A in just a few minutes and it looked nearly new.
I dont know why people dont pay attention. You handrub it with the plastic polish made specificly for that. You cant burn it by hand and costs less than $10. Takes all of 15 mins to do a dash in the car without removing anything. If you cant do that, bring it by and ill do it for you for free.
