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:
