Just finished having this neat space age set restored,, working great. The front of the screen has a tinted clear curved removable cover that over the past 40 years had become cloudy and I cannot clean it with any plastic polishes. Has any one had any good results with any other options to clear cloudy resin or plastic covers? I see that there is a heat process that works, but I do not want to melt the cover. The cloudiness is thru the entire plastic, not a scratched surface. Any suggestions appreciated.

I wonder if some of the products sold in auto supply stores to restore cloudy headlight lenses might work in this case.

What polishes did you try?

How do you know the cloudiness goes all the way through the material?

A guy near here is trying to sell an Orbitel with a broken cover (chunks missing). I wonder if anyone has ever tried to make a repro cover?

All the Novus polishes, Mothers for headlights all fail. The cover is cloudy, or milky, not the usual discoloration like on auto lenses. I think it is just from it sitting somewhere for 40 years. The surface is perfectly smooth, but not very clear. It was originally a smoked plastic cover. I asked Mark Palmquist, that makes radio covers, and he has no interest. I did see on You Tube where some kind of torch cleared the plastics used on pinball machines that were cloudy, but I do not want to ruin the cover. I am sure there is some way to fix it.

I agree, don't use heat.
A replacement would probably be your only option.

Before trying something drastic like a torch, you might consider making a mold for reproduction, using your cloudy cover as the model for a mold. This company supplies casting products and has lots of info about techniques:

Even if you're not interested in making a repro right now, at least making a mold would give you some kind of fallback if your torch turns the cover into a puddle.
