Check this out. Retrobrighting using only sunlight. This is a total game changer.

Makes sense. My greatgrandmother and generations before her used to put their laundry to a meadow to let it be whitened. But I though yellowing itself is caused by the sun, this is strange. Basically this means if my Amiga was outside her whole life, she would remain white?

I don't actually have any equipment which needs retrobrighting at the moment. Can someone with a yellowed piece of hardware please put it in the sun for a day and post the results? |

Imagine yourself on the beach for three days, with you Amiga. You will become more and more brown, while your compi becomes more and more bright

Obviously plastic is different to skin, but yeah, quite strange how one brightens and another darkens. I'm genuinely shocked that this works. Maybe it's actually darkness that yellows our cases!

Its not a new method, been reported in other places some years back.
Some people who tried it back then also reported that the items yellowed again quite quickly and became very brittle. Seems like there's no magic solution to yellowing |

It kind of works.
But depending on the machine needs some time. My A600 was super white after like a few hours in the sun. But my A1200 has accumulated like 20 hours of bright sunlight, and still isn't completely white again. |

Living in Australia under extreme sunlight, we know all too well about the bleaching effect of sunlight on plastic. We also know how destructive this process is. First bleached, then gets brittle, eventually disintegrates.
Use this with extreme caution. Last edited by alpine9000; 06 June 2019 at 11:23. |

It's the heat, not the UV from the sun, that yellows the cases due to a chemical process that happens. Most people stock their old computer stuff in tight and very warm places like the garage or attic. And if they dig it out a few years later it's yellowed. Put the cases in the sun and it gets brighter. Until it breaks some day when all plasticiser are gone, as alpine mentioned. You can't sun bleach/retroright the cases endlessly.
Actually well known since a few years. Read that in Forum 64 ages ago. Last edited by Retro-Nerd; 06 June 2019 at 17:01. |

No wonder PC manufacturers did away with beige cases and used more metal in the chassis, and only black plastic for the front plate - harder for it to go yellow, then. Imagine an all-metal Amiga case shaped like an A500!

I really can't, Miggy = white/broken white/beige. Anything else is not an Amiga. I remember seeing advertisements for a black A600 and it just didn't look right.

No, I never saw the CDTV or the CD32 as part of the Amiga lineup, they were other Commodore products. And quite frankly, closer to being actual toys.
