Subject radio is a Westinghouse H-334T7U, and the clear plastic dial is pretty foggy. I've tried different grades of Novus, Plasticx gel, Go-Jo, and even the stuff auto parts stores sell to clean headlights. Nothing seems to work. Am I fighting a losing battle, or possibly my technique isn't quite right?
Thanks!!
Ira

If those products didn't work it's probably time to order a new dial from Mark Palmquist:

There are tutorials on making your own, but Mark makes very nice dials.

Thanks, John, but this isn't that type of dial cover; it's hard plastic with the frequencies embossed/molded in. I've got covers from Mark before (he does a great job), but haven't see one like this.

OK.... then try some Mother's Mag and Aluminum polish (auto section). Practice on another piece of plastic and you'll want to follow-up with finer grades of abrasives such as Novus 3, then 2 etc. It will take a lot of elbow grease with each , but hopefully that process will cut through the layer that is discolored (unless it is all the way through).

I have had great luck with Mcguires Plastex which you can get at Walmart in the automotive dept... Its made for polishing and taking the fading and yellowing out of automotive headlamps... Works great!

Try a dab of Simichrome polish on a microfibre cloth.
