Take a look HERE (http://www.amigahellas.gr/modules/newbb/viewtopic.php?topic_id=1198&forum=9&viewmode=flat&order=ASC&start=30)

Language is Greek, but you can see the pictures. Actually the last one shows the result better.

Amigakas disassemble A1200 and after that he used "Tamiya plastics acrylic spray" twice. His Amiga is like a new one except the keys  :-P

The darker colour of the plastic is caused by chemical changes in the pigmentation and cannot be washed or bleached away. The only sure method is a respray using a plastic paint. People have put the keyboard case in a dishwasher without damage, but I doubt it does anything for the yellowed appearance.

If the plastic looks yellowed after you've exposed it for long time at sunlight, you can't do almost anything. But if it shows traces of smoke, dust and so on... you can obtain great results.

Couldn't of said it better myself
*Thanks*

The good thing about the stuff is that it doesn’t seem to be brutal to most surfaces, unlike some other cleaners.

I've had good luck with "Flitz" metal/plastic polish reducing mild yellowing, but you have to be very gentle as the polish can change the surface texture if you get too aggressive. (Especially with A1200, A600, and later 1084 cases. The earlier stuff is much tougher - for a test, I hit a *badly* yellowed A500 mouse, after some fairly heavy rubbing it looked almost new, and the surface texture was still 100% intact.)

For anything more substantial, plastic paint (dye type) is the best idea IMO, as it penetrates into the plastic without leaving a coating... no dust inclusions or runs to worry about.

Also, I use Plexus for the occasional wipe-down, it keeps the equipment looking like new and protects from further yellowing.

It's important to note that even Tamiya white paint will turn yellow in time.
I've been through this making protoypes.

I find the best option is to paint my 1200 black. Even if the color shifts it wont be noticable as a black unit.
