Mix up a batch of Retr0brite?

>>5106369
You can’t. Retro brite strips a layer off and looks great but ultimately is only a temporary measure and it weakens the plastic structurally. The redox process has occurred and can’t be undone

Don't parrot crap you hear from other people without at least fact checking it yourself first.

>>5106369
there are probably millions of guides for this on google and youtube. But I say be like me and don't give a shit about the yellowing.

>>5106369
get over it your body is going to age a lot worse than that plastic

>>5106428
Are you dense? Retrobrite literally strips a layer of plastic off. It’s not possible to reverse oxidation

Check this parrot out lol

Retrobrite is a combination of bleaching agents and a thickener to keep it on the surface and thick enough not to streak. It's not a corrosive. It's not a completely inaccurate claim that it weakens the plastic but only fractionally and only a few micrometers deep that it penetrates. Sure the oxidation can come back and will likely come back faster but it can be re-treated or re-sealed after the initial treatment or even just polished.

I don't understand the amount of alarmists inundating this hobby. I suspect they're the same people who will angrily claim emulation is identical to real hardware that they "coincidentally" can't afford.

>>5106579
Yeah, real basic, but apparently still beyond you. To be fair, I expected an answer like this after you got done pounding on Google for a second time and coming back with nothing. "Retrobrite", chemically speaking, removes bromine (in the case of retro electronics, used as a fire retardant) from (most) ABS plastics through oxidation. Nothing more. This process is usually done via H2O2 and TAED. Please explain how this process affects the molecular integrity of ABS plastics. Use as many big boy words as you feel are necessary. Should be fairly simple. Basic fucking chemistry, and all.

>>5106610
>emulation is identical to real hardware that they "coincidentally" can't afford.
It is, in most cases. I have no trouble affording hardware, either.

>>5106428
I'm not that guy, I've just seen pics and figured that was the issue.

Yeah, because that guy suddenly being "gone" and you magically appearing at the same time to white knight him and try to hit the reset button on the conversation in the hopes of steering it in a direction that lets you avoid answering >>5106635 is a total (((coincidence))) right?

The amount of horror elements in this thread is staggering.

>>5106384
>it weakens the plastic structurally

That is true but it would only be a problem if your shell had a thickness of a few micrometers, but with the plastic being millimeters thick I wouldn't worry too much about the most outer layer...

>>5106610
>I suspect they're the same people who will angrily claim emulation is identical to real hardware that they "coincidentally" can't afford.
Imagine being this elitist about buying 20 year old hardware that's falling apart lmao.

>>5106415
That's like saying weightloss doesn't work because there are pictures of fatasses who dieted down and then went back to their old eating habits and ballooned up again.

the plastic will always be susceptible to yellowing because what it's made of. But retrobright resets it.

>>5106749
How new you are to not know gramps babbage is /vr/'s equivalent of Virt?

Just filter this namefag. He's constantly posting inaccurate bullshit on this board mixed with the occasional anecdotes to feign credibility.

>>5107109
So where's the inaccurate bullshit of his in this thread?

>>5107141
Did you even read anything he posted? Every post of his is like this...

>It's not a corrosive.
Retr0brite is basically hydrogen peroxide which by definition is an acid. If it's not corrosive then you wouldn't need to wear gloves while handling it.

>Sure the oxidation can come back
The yellowing is not from and has nothing at all to do with oxidation.

>>5107171
>ydrogen peroxide which by definition is an acid.
Yeah, a fairly mild one. And while yes it is an acid it isn't an acid "by definition".
>If it's not corrosive then you wouldn't need to wear gloves while handling it.
You don't. One of hydrogen peroxide's chief uses is as a topical antiseptic. You'd have to have a pretty strong concentration to run into any real problems outside of possible mild irritation. Certainly not the stuff you're buying at the local drug store to treat a skinned knee or whip up a batch of retrobrite.

Please, for the love of God, just stay in school.

>>5107171
>>It's not a corrosive.
>Retr0brite is basically hydrogen peroxide which by definition is an acid

You don't wear gloves because it's an acid, you wear them because it's- surprise surprise!- a peroxide. Ever seen what it does to your skin in higher concentration?

>>5107213
It's that kid who got fucking destroyed earlier trying to come back yet again and hopefully "win" a different argument.

Not even him and let me laugh at you.

>>5107171
>>5107187
H2O2 is barely even an acid. Certainly not strong enough to be relevant to the topic at hand.

>>5107218
>Ever seen what it does to your skin in higher concentration?
Can confirm, spilled 50% h2o2 on my hand years ago, skin went tingly and white (pic related, my hand)

You can use google to verify. The plastic WILL turn yellow again. The chemical compounds (bromine) still exist in the plastic. They will yellow again. All the "retrobrite" does is oxidize and remove the visible layer of yellow plastic where the break down from UV light has happened. Unless you chemically remove the bromine (impossible) it is only a temporary fix, and does weaken the plastic a bit.

>>5110726
It's EITHER temporary, or it weakens the plastic, can't be both. If it's affecting the entire plastic structure then there won't be bromine lurking just underneath, and if there is then it's because the cleaning process has only affected the surface layer. My understanding is the latter is true - you only clean the surface, the plastic underneath is unaffected, and the surface will re-yellow in a few years.

>>5110749
>only affected the surface
If you remove or oxidize the top few microns of plastic, you are destroying the structural integrity. It is minimal, and imperceptible, but it is still destroying the top layer of plastic. The oxidization process destroys things. Rust is oxidization. It weakens metals. It is not just removing the color, it is destroying the top layer. It may be minor, but it is still weakening it.

Try cleaning your clear coat of your car with retro brite, and in a few years your clear coat will be peeling off in places. It weakens it because it damages it. Thinner plastics will be more noticeable.

>>5106386

>>5110804
>Fuck it, it got old. Stop being autistic.
I have read quite a bit about retrobrite and it being a temporary solution. If the color bothers you so much, one suggestion I read about was to disassemble the unit and paint the original color. A quality spray paint will not yellow as fast as bromide plastic. It is simply easier to let it alone.

https://www.classic-computers.org.nz/blog/2013-01-15-retr0bright-only-temporary.htm

The original damage from light causes degraded or free bromides throughout the case from the fire retardants. Retr0Bright only takes these away from the surface layer. However these bromides can migrate fairly freely through the polymer. They don't need light to do this. Migration is probably accelerated in hot conditions. These pre-existing bromines from the original damage migrate to the top and within a few years the surface is yellowed again. The rate of the regression depends on the inital extent of yellowing (the more yellowed, the more bromides down deep), heat exposure and the nature/quality of the plastics.

Our experiments showed that it is not recommended to use RetrObright or Hydrogen Peroxide on the types of plastic we studied. As you can see photos taken through the microscope, both products caused an etching of the surface, which was also visible to the naked eye. After purification with hydrogen peroxide on polymethyl methacrylate (PMMA), a clear cracking could be seen in the area where the solution was applied. Polyvinyl chloride (PVC), on the other hand, became food and the photograph shows how the soap-like gel has eaten a bubble-like pattern in the surface of the material.

>on the types of plastic we studied.
>Yvonne Shashoua and I have tested this week if you can clean other plastic types with RetrObright
The entire point of the article was testing on OTHER non ABS plastics to see how RB worked on them. Did you really think no one was going to bother to translate and read the article for themselves?

>>5111071
I mean we are all just guessing anyway, nobody has posted proof (i havent seen any anywhere) the exact yellowing mechanism - bromine is just a plausible guess. One chemist on stack exchange claims bromine is unlikely the culprit.

Why not plasti dip it? You can always peel it off...

Is that the video where he concludes that you would end up doing this every two-three years because the yellowing would inevitably come back?

Even tap water can corrode you if you're a paper skinned faggot. The primary action by which peroxide works is not corrosion though and even the line between "cleaning" and "damaging" in general can probably be erased completely if you're pedantic enough

Gramps, please stop being so fucking retarded. Corrosion is literally oxidation. Guess what peroxide does to things.

>>5113284
>>5113292
Again with the pedantics. Hopefully OP has long ago gotten the actual useful information he was looking for because there ain't been none in this thread for a long ass time now.

>>5106661
right, you can see the red outline. fucking idiot! im talking to about you >>5106654

If Retrobright indeed works by solving down the yellowed part of the plastic, then it would make sense that it makes the plastic weaker, since it is essentially removing a thin layer. It's like when you resurface a scratched disc, you do it by peeling down a damaged layer - but it means you have less material remaining.

And it's completely worthless, since the cause of the issue (the bromine) is still in there, still reacts with the plastic, and yellows it back again.

I'm only hoping that enough interest is done in retro hardware so new parts can be manufactured as replacements. I know that there's a project to make new C64 keycaps, for example. But less popular hardware may never get that treatment.

Sand it with .0000 grit sandpaper so you can control how much comes off while not putting any deep scratches in it.

In coin collecting any sort of cleaning or refurbishing actually lowers their value. Wouldn't you want it to show its age?

And of not, then why not just go all out and make it interesting?
