Make Yellow Sega Saturn White Again

Ever notice how your sometime gadgets have turned an ugly yellowish color since you bought them? Old Macs, Commodores, Nintendo systems, and other machines look dreadful 30 years afterwards—but there is a manner to brighten them upward again.

Why Old Plastic Turns Yellow (and How You Tin Make Information technology White Once again)

This yellowing happens thanks to a flame retardant chosen bromine in those former ABS plastics. When exposed to UV lite, those bromine molecules tin can destabilize and leech through to the surface, causing the plastic to plow yellow (or even brown if left long plenty). Modern plastics have improved the chemistry so this process doesn't happen, but those old machines from the 80s aren't so lucky.

Different retro machines will yellow at dissimilar rates than others, even from the aforementioned line of products. Your Super Nintendo may be much yellower than your friend'due south, just because they were from different batches of plastic. Here's what's even weirder: sometimes, two pieces of plastic in the same machine tin can be unlike levels of yellow. The Super Nintendo we'll be using equally our instance today, seen below, has a much yellower base than top.

The cartridge slot shows the original SNES color. Y'all can see the surrounding summit example has yellowed some, and the bottom case has yellowed a lot.

A few years ago, some enterprising and chemistry-savvy forum users discovered that hydrogen peroxide could help remove these free bromides from the plastic, restoring the original white color. Information technology isn't permanent, unfortunately, since there are withal costless bromides deep in the plastic that can re-surface later on another few years. In addition, some people think the process makes those plastics more breakable and fragile. But if yous're willing to put up with those annoyances, it'southward a peachy way to make your retro gadgets brandish-worthy once again. They created a recipe of ingredients and dubbed the formula Retr0bright. You can read more than about it at the original Retr0bright page, and more about the science in this corking blog post on the subject field.

In that location are plenty of guides out there, but after trying it a few times ourselves, we establish that—while most guides are quite decent (including the i linked in a higher place, and this fantastic video from The 8-Flake Guy on YouTube)—they gloss over some important details to brand the process equally polish as possible. Then today, we'll show y'all how to de-xanthous those onetime gadgets, using a super cheap solution you can buy in a canteen.

What You Need

Since Retr0bright'due south creation, many people have come up up with different methods for Retr0brighting their systems, with different advantages and disadvantages. The original Retr0bright recipe called for 10% hydrogen peroxide solution mixed with a few other ingredients to requite it a more flossy consistency. Just later on a while, some people plant that this "recipe" was unnecessary: you tin can already buy a creamy hydrogen peroxide solution in the form of hair developer (the 8-Scrap Guy calls information technology "Retr0bright in a bottle"). Head to any beauty supply store and ask for 40 Volume Creme Programmer and y'all're in business organisation We're using this $3 canteen by Salon Care from Sally Beauty.

Note: Some people recommend submerging your plastic in a tub of 10% to 15% hydrogen peroxide liquid instead of using the cream (no college, or yous'll increase the chance of blooming and streaking). Granted, this is easier (and a flake less probable to cause streaking), but it's more dangerous, not to mention expensive. Plus, it doesn't let you much control, equally everything will exist covered—you tin't avoid labels or other lettering. Equally long as you lot follow our instructions to the alphabetic character, the cream should work well, with minimal streaking.

Autonomously from your Retr0bright of choice, you only need a few other things:

• Rubber gloves: I highly recommend some sort of hand roofing, since you don't really want to get this stuff on your peel, as information technology'll give you a squeamish chemical burn. You tin can get some from the beauty supply shop besides if y'all don't have them already.
• Safety goggles: You should absolutely wear some sort of protective centre covering, since you definitely don't want to become this stuff in your eyes, as it tin can blind yous. (Seriously,practice not skip these!)
• A paintbrush or tint brush: You lot'll also want a brush to utilize the cream. An quondam paintbrush volition work, only you can besides grab a tint castor for a cadet or two forth with the developer at the beauty supply store—that's what I did.
• Cling wrap: You'll need this to forestall the cream from evaporating, which will help you get an even result.
• Rubbing booze: You'll want to clean the plastic before you Retr0bright it. Relatively make clean devices volition probably but need water and a rag, but denatured or isopropyl alcohol is rather useful for getting some of those tougher scuffs and clay marks off.
• A screwdriver (and any other necessary tools): Lastly, you'll likely need a screwdriver to take apart your gadget, forth with whatever other necessary tools (some Nintendo systems require a special bit to become it open, for instance). I too apply a magnetic screw tray to keep all those little screws organized, only that's optional.
• A UV light bulb (optional): If yous have the space, and don't want to leave information technology out in the sun (which requires more attention to avoid streaking), you tin can apply a UV light in a separate room. I didn't opt for this method myself, simply I've heard skilful things about it.

One time you've got everything in 1 place, read through the instructions below very carefully before you get started.

Step Ane: Disassemble Your Hardware

If at all possible, nosotros highly recommend disassembling the device in question before you start cleaning and Retr0brighting. Ideally, you will break information technology down to but the plastic parts you want to make clean, with all the metal pieces and circuitry prepare aside. This will make the cleaning much easier (since you'll be able to hose information technology off), and avoid any bug with the Retr0bright harming the internals.

This process volition differ depending on what you're taking apart, and so striking up YouTube for a "teardown" video of your specific gadget—chances are, there are probably a few out in that location. Set aside the internals and make sure you don't lose any of the screws (again, this is where that magnetic screw tray comes in handy). Once y'all accept simply the plastic pieces left over, you lot're ready to start cleaning.

Stride 2: Make clean the Plastic Thoroughly

Again, this step will differ a bit depending on what y'all're cleaning, but in general, I've found that a thorough cleaning of the plastic contains two or three steps.

First, clean any grit, hair, and dirt off the plastic with plain ol' water. I like to give mine a nice spray with the hose, which helps go far all the petty cracks, grooves, and vents. Dry it off with a rag when you're done. (You can also wipe it down with a wet rag if you'd prefer not to spray it with the hose—like if at that place are some internals y'all couldn't dismantle).

In one case the plastic is dry, you lot'll probably find that there is nonetheless a lot of grime on it, not to mention scuff marks and other blemishes. To make clean that off, I recommend taking a rag and some denatured or isopropyl alcohol and putting some elbow grease into information technology. A lot of the grime and scuffs should come correct off, while others may need some serious rubbing. Brand sure you lot stay away from lettering and other painted-on graphics, as the alcohol will impairment them! (For example, the red lettering on the front of an original Nintendo system will rub correct off with booze.)

You lot may observe, even after your arm is sore from rubbing with booze, that some scuff marks don't come off. In this example, I often plow to the Mr. Clean Magic Eraser. It will most always get those scuff marks out, but note that it is an annoying—which means it may remove some texture and finish from the gadget. If that worries yous, y'all can skip this step. Myself, I'd rather risk a slightly shinier spot on the plastic than look at blackness scuff marks. It's upwardly to you. Only exist sure to showtime lightly, and rub harder simply if you lot need to.

Footstep Three: Utilize the Retr0bright

Once your device is make clean of all other dirt and grime, it'south time to plough our attention to those pesky Bromides. Enter Retr0bright. Y'all'll demand aplenty sunlight for this office of the process, so I recommend getting started early on in the morning and then you can get as much fourth dimension in the lord's day every bit possible—otherwise, you may have to do it a 2d day. Yet, you may desire to do this first part in your garage or another enclosed area, then the breeze doesn't blow the cling wrap effectually while you're trying to work.

First, I like to embrace upwards whatever labels with Scotch record to protect them (especially the paper ones, which will disintegrate when soaking in liquid or foam). If there are any painted-on messages, you may want to avoid those pieces, as the Retr0bright tin fade or damage them. In general, I recommend only Retr0brighting the very low-cal plastic pieces—smaller buttons or darker colored plastics are probably fine every bit-is.

Adjacent, afterward putting on your gloves and condom goggles, lay out your cling wrap—you may need multiple pieces if your gadget is big, since it needs to encompass it completely—and pour some of the Retr0bright on the cling wrap. Spread information technology effectually with your brush, then cascade the Retr0bright on the plastic. Brush it around too. Don't be afraid to use a lot of foam, every bit you desire to liberally cover every inch of the yellowed plastic. (You can even practice the inside, if it's yellowed, though that may not be necessary on some parts.)

So, put the plastic slice on the cling wrap and wrap it upwards. The idea is to seal it upward overnice so you lot can keep the Retr0bright from evaporating, which will crusade streaking. Again, full plastic wrap coverage is important.

Repeat this process with your other plastic pieces.

Step Four: Leave It In the Lord's day, Rotate and Re-Apply Regularly

Once your plastic parts are all wrapped up, put them out in direct sunlight (or under your UV seedling). UV exposure may take caused this mess, but it'due south also the hush-hush ingredient that will help u.s.a. clean it up. You'll want to leave it out there for a few hours, and so find a spot that gets straight sunlight for about of the 24-hour interval if you tin can.

Here's the important role: endeavour to work out as many of the air bubbles as you can and spread the foam evenly. And then, every half hour, rotate the pieces 90 degrees, and (with your gloves on) massage the Retr0bright around the plastic from outside the cling wrap. This keeps information technology moving around and stops air bubbles from staying in one place for too long, which is how you go a blotchy, streaky terminate. If you lot don't practise this, you will get bad results!

Lastly, it's all-time to rinse the parts off (run across the next footstep) and re-use a new coat after the creme starts to look more similar a cream, ordinarily afterwards two to three hours depending on how hot and sunny information technology is. This keeps the Retr0bright from drying out and causing blooming/streaking.

It sounds tedious, but it's well worth the effort. Later vi to nine hours, you should come across a noticeable improvement, though you may exist able to get by with less if your plastic was only a little xanthous.

Step Five: Rinse It Off, and Echo If Necessary

In one case the plastic looks like it's sparkly white again (or if you run out of sunlight), unwrap the pieces and rinse them off, either with a hose or in a sink (far abroad from food). You will likely demand to rub backlog Retr0bright off the plastic, since it'll be pretty thick and foamy and stuck on there, then clothing your gloves and give it a good, long massage under the h2o. Be sure to go far all the tiny cracks and crevices, as the Retr0bright volition definitely get stuck in those areas and yous'll need to scrub it out.

Y'all tin can dry the plastic off with a rag if you want now, or go out it to drip dry out. Once it'southward dry out, y'all should find that it looks much better than earlier!

If, notwithstanding, y'all detect that it's however yellower than you would similar, feel complimentary to repeat the procedure the next solar day. Some really yellowish plastics may need a few days in the sun to whiten up. My Super Nintendo, for example, looked better later on vii hours:

You tin see the top example at present matches the cartridge slot, but while the lesser has improved, it still has a fashion to go.

But the lesser piece needed a whopping 24 hours in the sun to really get back to where it should be. It was a lot of piece of work, and I did get some blotchiness on the lesser from not re-applying often enough. It isn't perfect, but overall it looks mode better than it did before:

Simply like 1992!

So just keep doing it until you go the results you want.

---

One time you've thoroughly rinsed and stale your plastic, and you're happy with the results, you're all done! Re-assemble your gadget and it'll exist just like the day you bought information technology, fresh and white from the mill. Recall, information technology volition re-yellow after some time—fifty-fifty if it'due south kept in a dark area, since those costless bromides are already loose deep in the plastic—but you tin always go through this process over again if it gets too yellowish for you lot.
