Yellow haze on climate plastic screen

So this is really on the exterior of the plastic of the screen I mean I would think that whole panel wouldn't be the worse very much I see them at the junkyard somewhat I've never pulled one and taken it up to the counter with my other stuff and the ones I see in the junkyard look relatively clear the two that I have here are clear that's really strange I would think of buffing wheel on your Dremel and any of that headlight cleaner one step type of paste should probably get it I don't mean sanding and all that just the McGuire's Plasti X and use the white buffing pad on your Dremel not too fast and keep it wet and just go over the whole thing real good then wipe it with a sponge and see what you're looking like I would think you should be able to do this little screen fairly quickly

 

The sun is was made it turn yellow, don't put it in the sun.
Try some mothers aluminum polish. I've used it on the head lamp lenses.
And other plastic on old meters and radios.
Rub it on with your finger in a circular patern than us a micro fiber cloth to clean it off.
Not 100% guarenteed to clear it up, but shouldn't hurt it.
