I've actually gotten really good results using just the 3% hydrogen peroxide sold at major grocery stores, large zip-up sandwich bags, and sunlight - it takes far longer (2-3 days in direct sunlight during the peak of summer), but that basically just meant I had plenty of time to rotate the item to ensure it'd de-yellow evenly.

I was a professional housecleaner and ive used hydrogen peroxide over time on a lot of kitchen appliances & assorted surfaces. i know its properties and uses well. Peroxide does seem to be the #1 most effective choice to reverse the yellowing of plastic. Commonplace as hydrogen peroxide is, most users dont really know that at any strength it is simply H202 which is essentially WATER (H20) with an extra oxygen molecule H202 (ozone is H203) the extra oxygen molecules easily detach to cause enzyme reactions and THAT is the activating (bleaching) factor with the residue being pure water. H202 the cleanest clean possible. The action is the same matter what the various strengths (% & volumes) for different purposes are. Drug store peroxide is 3%, hair bleach activator is 6% (20 volume) to 12% (40 volum Oxyiclean has 18% and a pure pharmaceutical grade of H2O2 is a whopping 35%) H2O2 "power water" is safe yet misused it isnt. Oxidizers can be highly corrosive. At 3% medicinal peroxide is used to explode oxygen hating bacteria clean wounds, & dissolve blood & dead tissue. BUT exposure to pure OXYGEN at even 3% will bleach hair lighten skin & whiten fingertips. Higher strengths are potentially harmful & require precautions to avoid brief but painful chemical burns) H202 may oxidize some metals but it has no ingredients that will damage plastic. Its potential bleaching action on yellowing, (how well it bleaches and how long it takes) would amount to how MUCH oxygen (enzyme) is present to interact and how deeply it penitrates the surface. Heat & or light may help it penetrate but I am guessing that oxyclean which contains baking soda (sodium bicarbonate) might be more effective than hair peroxide.abd frequent application might be as effective as soaking Im also wondering if retrobrighters have tried just keeping a brown bottle of drugstore 3% peroxde handy to daily wipe down their devices? I suspect it would both slow the yellowing & reverse it gradually over time...

Tips coming from experience... No plastic bags or wrap! Just a clear plastic storage bin, sunlight and patience. I will do three light/thin brush coats a day for 1-3 days with great success. My first go with plastic wrap and sun resulted in blotches where the plastic clung and where it didn't... Hosed a perfectly good IIgs case this way :( Two other points: -No retrobrite on Painted surfaces!!! (Watch out Commodore guys, maybe others) many monitor bezels can be painted though they appear plastic. Same with badges, lettering, etc... The Peroxide will deteriorate it to the point it will often wash off directly after your treating it. -I have many times done keyboard keys in a 5(water):1(peroxide) solution in a clear plastic bowl, with clear plastic cover. Keys ALL came out evenly with out all the fuss of brushing on Peroxide and trying to lay keys out oriented up. Darned nifty. Mix, dump and submerge, cover and go! AND THE FIRST RULE OF THUMB!!! Try simple rubbing alchohol and a magic eraser sponge first! You might be VERY surprized with the results. (also search for dry erase marker to get out sharpie) :) All the Best!

I think for certain things, its much more beautiful, especially knowing you created said patina.

Well known by now (this video is now over 4 years old), but worth posting here. One of the reasons the sun works very well is the heat it generates. So when using artificial light, either warm the solution or provide heat to the enclosure. Obviously not enough heat to melt plastic. More heat = less time necessary to brighten. Less time = less potential for bleaching damage, plastic deterioration or streaking.

The original Apple II or II Plus shouldn't need to be Retrobrighted, because its case is painted. Same thing with many TRS-80s. And Retrobright rarely turns out well on cases that were originally supposed to be beige, like the C64. Like you said, people often go too far and turn them nearly plain white, when they were never that color even when new.
@ModernClassic7 жыл бұрын
I did do my C64, but it was REALLY yellow when I got it (I didn't take any "before" photos unfortunately). But I couldn't match the top and bottom, which you can sort of see in the photo at the end and I almost mentioned it. The top and bottom yellowed differently; the bottom's lighter now than the top, but still yellower. So, another example of how this doesn't really restore the original color, it just de-saturates and lightens, but at an unpredictable rate for each.

In this video, you stated that retrobrite does not change the molecular structure of plastic, but some years ago, it was studied and found that it actually does leave microscopic gaps once the bromine is reduced, which in theory would make the plastic structure weaker (perhaps brittle over time). Especially with repeated use of peroxide. I wonder if this is why the yellowing returns 10 fold over a shorter period of time, as it fills in these microscopic gaps when the bromine separates and resurfaces.😵💫 It reminds me of how plasticizers in some semi-rigid plastic action figures (like vintage He-Man, TMNT, etc), would separate and surface over the figures, leaving a sticky film on top. Plasticizers are an important component of the plastic, to keep it's structure supple. Once it surfaces, the plastic has been found to be less durable (more brittle). I wonder if by removing the bromine in these harder plastics, the effects are similar. I really wish there was a perfect solution to this problem. I'm contemplating experimenting with paint to match applications, using precise airbrushing and protective lacquer coats to replicate a perfect color match and surface finish, for certain items like a yellowing Super Nintendo, original classic NES, a Dreamcast and so forth. 🤔 This is a great video. Thank you so much for sharing it. Many valid points were made.

Heat can also be a factor which isn't mentioned a lot. Similar experiments have proven that standard off the shelf 3% Hydrogen Peroxide will work when diluted in water and heated to a significantly higher temperature. (70C or 160F is sufficient, but needs to be below the plastics melting point. ex. 210F for ABS) Essentially you can use a hotplate and heat diluted peroxide to around 160F with the part in solution for a couple hours and the process works similar. No light needed and no streaking. Another fact, most people mention that the retrobright process essentially reverses the coloring, which isn't true. Most people should be smart enough to piece together that retrobright is essentially just bleaching the plastic. Peroxide, especially high concentrate, is used for bleaching hair, which is why Salon 40 cream is found in salons and other 'beauty' stores. The more you know.

How about LEDs? Another popular light treatment in a completely different community is radioactive photographic lenses, specifically old Pentax lenses get really yellow. Just like retrobright, for a long time people thought UV was the only way the yellowing could clean out but recently a youtuber stuck one under an IKEA desk lamp overnight and compared the results, and it came out really well. This is probably also more energy efficient compared to fluorescent, and people are more likely to own strong LEDs than strong fluorescent lights.

After my tests, I don't see why any broad spectrum light at all wouldn't work. But if you're saying they did it without the peroxide solution, I'm not sure of the science of that, and I'd be skeptical of it working on ABS plastic. The thing the solution does is, when combined with light, it get the bromides off the surface. Just light isn't going to do that - it does the opposite, it attracts them to the surface. The retrobright solution basically reverses the process. But I don't see why you couldn't use LED's instead of fluorescent light with the solution; light is light as long as you're comparing the same brightness, spectrum and wavelengths. I could have replaced my shop lights with equivalent T12 LED bulbs and most likely gotten the exact same result.

Seems like (I am not an expert by any means, I just educated myself on the subject) that light is not the key, but the energy that is brought to help chemical reactions. Try with the solution you are using (3%,6%,12% H2O2, Beauty Salon cream, etc.) and heat it up to some degree (nothing crazy, 120-150F) and compare results with the non-heated version, and you should see acceleration. You can try it in a pitch-black room to be sure that light is not the factor, but the energy. In my opinion, the Vapor retrobright setup should work pretty well, a sealed container with the solution on the bottom, items to retrobright suspended in the air over the solution on some mesh or hangers, and a heating mat with controlled temperature under the container. The solution will start to evaporate, and cover the items evenly. Try to keep the container to a solution volume not higher than 10 to 1, to try to make solution and evaporation as effective as possible.

You'd have people like Mark Novak advocating for armory level damage mitigation (boiling light surface rust to convert it to bluing). Is cleaning something up and preserving it damaging the value or increasing the value? There's really no easy answer to the questions. But it's fascinating regardless.

Thats a good comment on how exactly they used to look, simply because we had no way of photographing them in digital. One way, is to find either a New-Old-Stock machine, assuming it too hasn't yellowed, or as damn as close to NOS as you can get - can get expensive. One of my 2x 800XL machines is NOS, and it's in it's original colour - I know this because I had one in 1984, and it's light beige. My Atari ST 1040, is light grey. My C64, is definitely brown. You can get those Aldi ones in light beige. I've seen Amiga 500 machines almost white in colour, that is not what they originally were. The A1200, was much closer to white than the old A500. It's a shame that, back in the 80s, all machines weren't more like the Commodore 16, or Spectrum - Black, in colour.

This actually worked quite well. So well in fact that I had to had to back-off on the keys so to not erase the white paint markings on each key. The case itself came out great. Huge difference. An evening well spent, right? Well, only one thing... the plastics look as I remember but are now rather brittle. I don't know if I caused the brittleness or not, but it's something to consider. I think every "retrobright" method removes part of the plastic and so makes it weaker. I conclude that if you don't go too crazy, the windex/water/green pad method can clean it up just enough to look good without *bleaching* the plastic as you so well put it.

The only reason I would ever "retrobrite" an item is if it has discoloured unevenly, so that it could hopefully re-colour evenly over time (which all pieces do eventually, don't anyone be fooled otherwise). I'm with you on this one, I would much rather buy an item in its original state, regardless of its condition.

I don't have tons of experience retrobrighting but some, and I could SWEAR it makes some plastics become brittle. So for fragile or thin plastic parts I think it is slightly risky. Ever since I had that experience I've been pretty turned off the process.

I've been experimenting with this and I've been getting the dreaded streaks. It honestly looks like the peroxide is just baking onto the surface of the plastic. I hadn't considered the brand--it's a small bottle of the 40 stuff I found at CVS. I was thinking the plastic wrap bubbling is what led to the streaks, so I may try the bag option and try to keep the bag from touching the surface. I also want to try the submersion method, but that requires a lot of the liquid type depending on the size and container. Very interesting how it works under shop lights. I really wasn't expecting that, especially since heat seems to be a factor as well. (See 8BitGuy's boiling experiment)
@ModernClassic7 жыл бұрын
Yeah, I watch 8 Bit Guy too and respect him, but his results don't always line up with mine. Light with no heat whatsoever clearly works - in fact it was about 60 degrees in my basement during that test. My guess is that you can both yellow and de-yellow with light *or* heat; you don't necessarily need both, but both work either separately or together. They probably work better together, although I haven't tested that.

Very methodical! I need to try this on synthesizer keys, but it is not possible to remove them. That means clean up will be arduous and application will take time and attention to detail. If you have any important suggestions please let me know. I have tubes installed over my fluorescent lights (which happen to be right above the synth) to filter UVA and UVB. From your comments it sounds like that is a non-issue.

People should know how dangerous high concentrate H2O2 is as well. I don't know how much is in the salon product (typically schools/labs will use a max 30% which is still considered dangerous), but you should be super careful handling it. Leaving it on your skin will end up being extremely painful. High enough concentration can either light on fire or explode from heat. Its also very corrosive, so since the plastic yellows again eventually you may end up disintegrating it over the course of retrobriting repeatedly. I've never heard of this happening with whats commercially available, I doubt it ever could. But this is why its more or less impossible to get anything higher than 3% over the counter.

Great video! I'm going to attempt a retrobright on my friends gameboy that I bought from him because like you said, I don't have the memories so to me, I want the "original" look. He also wrote his last name in paint on it and after attempting to scrub it off with isopropyl alcohol I was even taking off the OG Nintendo lettering and the name STILL didn't come off. At this point it's just a restoration project of my own, and I'm just happy to have a piece of history (I was more Gameboy Color Era). But I can agree that if it was YOURS originally, that patina is a nice edition, albeit cosmetically off-putting.

I had a Power PC 9500/120 and a 1998 Compaq Deskpro EP/SB. They were bought yellow already and were corporate-owned when new. I try to imagine how many chemicals they resisted on their early cleaning because both of them started cracking. Every time I moved the Apple somewhere, bits of plastic were falling on my hand or around else. Gone to garbage! The Deskpro was at least more resistant, but when I was tinkering with it, any handle or joint from any removed piece cracked. Garbage again! I still have a Compaq Presario 5000 and this was bought new in 2001. Yellow keyboard, but I don't intend to retro bright it. Just clean it properly and keep the history of it with me.

Another great video...I will be retrobriting soon...I am curious how high brightness led lights work vs the charged gases in an florescent tube...I will have to give it a try. Additionally, after retrobriting, some users have been using a flat transparent spray paint to coat the surfaces...this should prevent oxidation from air, but without UV protection...the components should still avoid daylight...cheers.

Wouldn't it be possible, after the retro right process, to coat the plastic in some kind of UV protective substance to avoid future yellowing?
@ModernClassic7 жыл бұрын
Yes, but then you've just encased plastic in plastic, which isn't exactly subtle to the naked eye. Also, it's not really reliable either. A lot of clearcoats that were initially considered "UV protectant" have themselves yellowed considerably over time. I guess they protected what was underneath from UV, but it's kind of semantic when the clearcoat itself yellows and darkens. Look at some vintage guitar color shifts sometime, for example.
@gamedoutgamer6 жыл бұрын
Yes ABSOLUTELY to slow the yellowing process you can coat the plastic in 'SHERWIN WILLIAMS 1377 KRYLON GALLERY SERIES K UV ARCHIVAL VARNISH SPRAY SATIN' or similar UV art protecting product. Satin is in between matte and glossy and is suggested for old computer/console cases. $12 on ebay. Will probably need a re-coat every so often not sure how often yet.
@thomasberry80126 жыл бұрын
Modern Classic I know this has nothing to do with the reply thread, but I was just curious if you'd mind explaining exactly how you meant "semantic" when using it in your last comment regarding uv clear coat yellowing? I'm aware of the word's meaning and can see why, you being a computer guy, would use it. I just can't exactly understand it's usage here. Are you basically saying that the logic of using the clear coat to protect from uv when itself yellows is debatable, or are you saying it doesn't make sense? Just exactly how is it being used here? I kind of have this affinity for vocabulary and your reply would be much appreciated! You, sir, are very well spoken, by the way.

Once something has been retrobrited, would one of the UV protection sprays make the effect last longer?Also, strictly speaking, xanthan is a thickener - a "stabiliser" is something that prevents peroxide from degrading (eg acetanilide, phenol, tin).

3 points, use a uv lamp , not Sun light, and chemically seal all newly brightened surfaces, this will greatly reduce 're- yellowing'. It has been claimed that whitening makes the plastic brittle, however this seens imporbable considering the interaction, and reaction (s) occuring.
