Removing Yellow Tarnish?

[fillosauru]

Hey, I tried the bleach thing myself, and it barely worked;
I did not get a white A500 case, but it was not so 'yellowed' as before the treatment.
And I left for a day in the bleach+water solution!
Let's say, half bleach and half tap water.
And the whitening was not homogenous, and as a result, I have a A500 case with pathches of white and yellow!  :lol:

When I first got my A1200,it had some of its keys slightly yellowed,especially letter F,and I too thought about cleaning it up.But you must remember that the Amiga yellowing is just a sign of ageing and I'd rather have a slightly yellowed Amiga that works fine,than an Amiga with a melted keyboard due to using some harsh cleaning substance being used on it.
Nothing stays new forever,so just enjoy the Amiga as it is. :-D
