Yellow A4000 front

[leofoe]

The front of my A4000 was very yellow. I read on this site that it would be very difficult to get rid of that.
So I tried abbrasive paper. It worked!
Waterproof abbrasive paper, number 240 did the trick. See some pictures:
Halfway...
Almost done...
Done!
The worst is yet to come... The keyboard!

I agree.  In the pics it looks almost A3000 beige.  But, the A4000 was almost white.  

However, it still looks better than before.  Good luck with the keyboard.

Have you tried, perhaps, immersing the face plate in bleach? Or perhaps a chemical solution like CLR ? (Calcium-lime-rust...maybe that would help? Dunno

I don't understand why does yellowing bother you so much, ppl?? And *removing* layer of plastic seems much worse to me than yellowing. IMHO, much better option would be to use some kind of paint, especially the one that could be easily removed some day.
Because, you might regret it. For eg, I'm sure that some people towerising their A1200 and A4000D would now prefer original case.

I tried bleach. It did not make the slightiest difference. Besides quickly having to get the door and windows open...

Well, I believe it is very ugly. I like it much better now. However, it doesn't look as new. And it will never. But I think with paint you can't get that new look either.

The surface on which the front is laid down, is pure white. So you can compare with the word Amiga on the last picture, how yellow the whole front was before.

Looks a lot cleaner (and better in my personal opinion) but no scratches?

hello

it was yellowed by the cigarettes smoke or was the plastic itself yellowed by the age/sun etc?

I have the same 4000/030 case (in a box now) that went yellowed by my cigarettes smoke but easily cleanable. (i can't understand from the pictures)

No scratches. It even becomes smoother then before.

I think from both. But from the sun is worst. It gets a few micron into the plastic. That's why you have to rub it off.
BTW: You DID pull out the battery, didn't you?

UV yellowing and smoke yellowing is very different.
tar can be removed very easy with some propyl/alcohol - and besides, it works like UV filter

deep UV yellowing from sun can be removed only mechanically like this, but it still looks very ugly  :-x  :-x  :-x

@leofoe:

Yeah, the front is not designed to be totally smooth. It, as most computer equipment, is made to have a slight uneven surface.

I see a yellow front and I want it painted black.
No colours anymore I want them painted black...

:-)

Seriously, I've sprayed computers black more than once, works like a charm !
The only difficult thing is the keyboard...
But you should get a nice black Logitech wireless kb and mouse :-)

I can recommend this, but on the other hand it's a question of taste :-)

Cheers,
