Any way to remove yellowing from old plastic dial faces?

If you don't want to replace 'em completely (weirdly shaped or other reason) you might be able to improve the situation with some fine grit sandpaper followed by rubbing compound. It won't get rid of the yellowing, but it will sometimes get rid of the subsequent cloudiness that often comes with the yellowing and make the dial easily readable again. I wouldn't try that on a lettered dial face though.

I know Antique Electronic Supply sells replacement crystals for Philcos and Zeniths, and I think they might have stuff for GE too, I'm not sure.
