Yellow To White

[Eco]

Some possible methods to remove the yellowing:

Acetone

I have tried using acetone. It works even for an extremely yellowed plastic, since it will actually remove some of it. There are some downsides, though:

- Hard to get the resulting whiter colour an even shade
- Hard to get at the all details
- Will make the surface of the plastic slick and shiny, instead of the porous surface that is the norm
- If you use it on the keys, will most likely destroy the lettering on them
- Eww, stinky

Tub of water and some bleach

I haven't tried using bleach yet, I read about it somewhere. Supposedly being submerged in a water+bleach solution will make the case whiter again, and could be usable for the keys.

Can anyone confirm if bleaching works well?  :-)

After having tried acetone, I would suggest that only use it if the other stuff fails to get the results.

Bleach sounds promising.. please post some "before and after" pictures so we see what works!

@HopperJF

Have you gotten around to messing with the bleach yet? We want pictures  :-D

Remember to set the white balance before taking pictures, if your camera allows for that.

I think the case looks whiter and cleaner. I don't think that scrubbing will help too much after the gunk on the surface is gone, you could consider adding more bleach and just letting it soak for a few hours :-D

Acetone will not melt the WHOLE thing (so it will not melt like molecular acid being poured on it). However, it will remove the surface layer, and the yellowing with it. I know, because I've tried it!

The process will make the typically porous plastic surface of an Amiga case smooth and shiny. It may be hard to get the yellowing out of all the tiny details. Depending on the method of application, you may also leave other marks on the surface.

Photography tip: If your digital camera has a "manual white balance" option, turn it on and use it on a blank sheet of paper. Your camera will then remove the colour cast induced by lighting conditions, resulting in a much more accurate colour reproduction, especially for white-ish surfaces like the case.
