If the plastic turned yellow cos' of the light then forget it, it cannot be made sparkly white again, it's a chemical reaction in the plastic itself. DO NOT TRY any agressive stuff on it, you will only make things worse, ever seen plastic been eaten away ?
A paint job is your only sollution. :-)
This is not strickly true. UV light is responsible for the yellowing, however it does not penetrate all the way through the plastic.
Find an inconspicuous bit any use a compound cleaner or burnishing paste to remove the yellow.
Dont forget to buy some elbow grease at the same time. :-D :-D
Firstly stick it in a dish washer with a couple of finish powerball tablets and you'll be amazed how it comes out.
