yes, I know what you mean. I've a HB201p and the keys have turned yellow. And this week i'll get a very yellowed SVI, well based on the pictures i got from the ad on Marktplaats. I'm really looking forward to restore the machines in their original color. Btw for the dutch MRC users, who want to make retr0brite. I got the xanthaangom at De natuurwinkel. I guess every town in NL has a reforma- or natuurwinkel. You need to have at least 10% of Hydrogen Peroxide. In the Netherlands you can't buy this at the "Aphoteek" so you need to go to a hairdresser shop (kapperswinkel). I paid 6.95 euro for 1 liter. Ofcourse you can also order everything on the Net.

This looks great! How long does it take for the keys to get cleaned?

1 day in the sun. You can also use a UV lamp.

hmmm..

I am not very sure if the cleaning is done by the fluids.
Some plastics grow yellow in the dark (lack of UV) and improve with some daylight / UV.

Simple cleaning (without disassembling) + some sunlight might work just as good.

one warning though: Too much UV may break down some plastic and/or colorants, make them look pale, and maybe even brittle (mechanical degradation)...

The Quickshot was very yellow. First I tried to cleaned it with Dreft; a common dish-washing detergent. But that only removed the fat and dirt. It was definitely the Retr0brite that whitened it. Also the other keys didn't turned white in the sun.

Have a look at the Retr0bright wiki page. It explains it all. Retr0bright has been designed specifically to combat yellowing in retro computers and is so much better than just UV.

retr0bright.wikispaces.com/home

I've known about the Ret0bright project for years from other forums and know that the guys have done a lot of experimenting and the current Retr0bright formula is better than everything else they have tried including plain sunlight/UV.

If anyone has yellowing on their old computer stock they should try Retr0bright but do make sure you read everything thoroughly before you apply it and also test the product on an area of plastic that is not normally visible to make sure there are no adverse reactions.

A fair possible warning for Retr0brite users:

Weather hasn't been to great, but I did put my stuff outside on the balcony, got it in inside ofcourse during night and the rainy days, but here's a result of patience of 5 weeks, by just putting it outside and giving it some sun.
