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!

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

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.

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.

It still looks awfully yellow to me... But maybe that's your white balance?

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?

No scratches. It even becomes smoother then before.

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)

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?

The first battery has been replaced under warranty in 1992-93 or so (don't remember now).

Then another one . . . mhh about 7-8 years ago (during a repair- Paula replaced) and recently i've replaced it after some rework on the mobo.

Why?

If you keep it in a box, you don't use it. And the battery will get leaking sooner or later. But if it's replaced recently, you have a few years to go. I had my A4000 in a box for years and now my clock is ruined. Argh!

It was yellow before I put it in the box... So it was too late already.
