I use a Salon Care 40 creme as well and have good results. Then today I retrobrited 2 monitor cases and got the dreaded swirl effect. I can't understand why -- we have weak Northern sun in Seattle, the cases were well cleaned first then well wrapped in plastic, but they developed strong swirls. Totally bummed!
The weird thing, is the keyboard and Amiga case next to it came out great using exact same technique.
Anyway to get rid of the swirl besides sand or paint?

I used Salon Care 40 creme on this A500 case (which was only mildly yellowed to begin with), never letting it dry out, no saran wrap or anything, under blacklights for a few hours, it looks terrible: http://i.imgur.com/bE3Y3ER.jpg
Is there any to fix this or is my case now permanently damaged?
Edit: I should note that it was not apparent it was turning out like this when I was periodically checking on it. It looked perfectly fine even when I washed it off while it was wet. Once I dried it the damage became apparent. So I guess a warning, don't trust how it looks from just wiping off some creme, wash it completely and dry it.

That's extremely frustrating. In the US A500s are extremely hard to come by and this is a PAL model I imported a long time ago. It didn't even look that bad and I feel really stupid for trying to improve it now. To anyone reading please be careful with this stuff, even if you're meticulous about it you can ruin hardware that's no longer being made and currently sells for insane prices. People will buy a yellowed machine but nobody will buy one that's obviously been damaged by chemicals

I use Clairol Pure White 40, and pre-clean the surfaces with baby wipes and then dry it off with a microfiber cloth before retrobriting.
I got the swirl look once on a case that was very yellow. It ended up looking like swiss cheese or something with some parts white and some yellow. I rinsed the pieces, cleaned them again with baby wipes and dried, and re-applied retrobrite to both the surface and to the saran wrap and put it back in the sun. After another few hours, everything cleared up just fine.

I removed the yellowing of a TO8.
I used my alltime favourite, a german mould remover called "Mellerud Schimmelentferner Aktivgel". This is the version with hydrogen peroxide.
The TO8 after:
I only sprayed the case parts once (all keys too) so that everything is covered well. After this i placed them in the sun for a couple of hours (the TO8 about 5 hours) and washed off the remaining fluid.
You should note, that there are many different conditions of the plastics and beside of this ... white is not white, grey is not grey and so on ...
