Re: Restoring the whiteness to yellowed plastic.
I had a number of 700 type telephones in black plastic bags stored in my dark attic for a period of more than 20 years. The ivory ones went yellow right through to the inside. Exposure to light may play a part in the degradation, but I don't think it's the only factor.
