We all know about the cosmetic problem of older computers: the nice beige or
white plastic the originally came with, is turning into ugly yellow. I have
it with TRS-80 model 4/P's, model 100, and Tandy 1000 (SX). Not with the
white coco's, because they are boxed all the time.
Does anybody have a cure, short of painting the machines ?

When I was an RS computer repair tech, long ,long ago I used Fantastik on a rag to clean the cases. worked really well to get rid of crud off cases, esp. those of smokers. Oviously done with power off, spray the rag, not the case....unless you tear done the units first. You might try a 'bathtub cleanser' for the really bad cases, but I'd tear down first.....

I saw a guy in a video game resale shop cleaning the yellowed gray/beige/white plastic gaming equipment with a toothbrush and some cleaner (but unsure what kind). Did a great looking job, though.
As a goof, I took a brillo pad and did a small 1 inch spot on top of an old, yellowed monitor just to see the difference 10+ years had made on it.

Does anybody have a cure, short of painting the machines ?
I was wondering about the answers in this thread... do any of you, who answered, mean that any of these products you mention can reverse the discoloration that comes from light?
It will always help to clean away any dirt, like dirt stuck in fingerfat, smokestains etc. I do that with pads for cleaning screens. Since they contain stuff that can attack some plastics (I think, but have never had any problems) it is a good idea to try first in a non visible place. Some stuff might even speed up the aging of the plastic/paint/lacquer.
Anyway, from the point of view when looking at antiques, the yellowing that comes from light gives pathos if it is not too bad, same with bleaching of dark surfaces. Some things discolor too fast or too much and it is not nice.
I have wondered if I should get hold of some paint to touch up the worn through places near the keyboard on my model III, but I am in doubt (if it's a good idea even if I could get a perfect match to the silver).

Back in the early '80s repainted my entire Model III. While mine didn't get the usual wear patterns where the palms rest, I did put the wrong screw in the front row of three and it protruded out the top of the case in front of the numeric key pad. What a heart break! So I shaved the protrusion with a razor blade then filled and sanded the lesion. After that, the entire unit got a coat of shiny Buick Silver (after proper masking, of course!). It was the brightest Model III in the universe (ha ha). I would swear it actually ran programs faster after that. :)

R/S made a stick on strip that covered up the wear spot on these - it was molded out of clear plastic IIRC.
Repainting R/S stuff (and the like) is always popular:
