A WARNING TO ALL, for I am currently in significant discomfort (by significant discomfort, I really mean great pain)! While setting up your tinfoil and the parts to be brightened, wear sunglasses! Everyone knows not to stare directly at UV LEDs/bulbs - what you may not consider is that even if you don't, the tinfoil will actively reflect the rays straight back up into your eyes without the sensation of pain that comes from directly staring at the bulb! It only took about ten minutes of fumbling around with my setup to burn my eyes and I didn't even know it had happened until a couple hours later. Now I have a case of photokeratitis, and let me tell you, it hurts. Bad. I just wanted to give everyone a heads up, because although I took care not to stare at my uv lights, I did not consider how much light would be reflected directly back into my eyes from the tinfoil. Be safe everyone! - Damn, it was hard to right this post half blind. On the bright side, if there is one, my Dreamcast looks as new as the day I bought it... But I discovered I didn't need the UV to achieve this, see in the comments below 👇.

[@LithicKing]

@@OhPleaseMary no problem my friend! Agony is the best descriptor, and I wouldn't want anyone else to experience it, I had to drink myself the sleep the first few nights. The UV lights can cast shadows that will cause uneven lightening ie dark and light spots on the finished part, so many people will be trying to adjust their parts with the lights on so they can see and eliminate those spots like I did. As long as you know the danger you can take precaution! I should mention too, I did a second batch of parts after a week of recovering, and this batch I used just heat as an additional catalyst instead of UV light and my results were just as good, Incase you'd rather go that route!

I've had good results with an alternative "dry (ish)" method 1) taking a cardboard box and completely cover its inside with Aluminium foil. 2) evenly coat the yellowed parts with a strong hydrogen peroxide cream like "SalonCare 40" (the cream adheres to the part without submersion) 3) suspend the parts in the cardboard box with fine wire/fishing line 4) hang a UV source inside the box (I used a small fluorescent tube but It seems that LED strips are now good enough too!) 5) close up the box, turn on the light and wait. (basically the same i guess except for the submersion and the parts being suspended instead of sitting on the bottom, to get all around bleaching.)

[@Eeu94]

This method worked for me, however, it only worked with my Nike shoes. With other hard parts it didn't work. Do you have any tips?

[@poneill65]

@@Eeu94 All the parts I tried were hard plastic, and all worked well. The only things I can think of to suggest are 1) use the stronger version of this salon gel (Salon 40?) 2) try to get a consistent thick coating all over. I used a paintbrush with delicate bristles to even it out. 3) The power of the UV source you use may be an issue. I haven't tried the LED's, I used the tube UV light in an old fly/bug zapper, so I can't really say what the UV power of that was. Also, maybe the "spread" of the light from a tube is wider than from the LED's and so gets bounced around the box better??? You could combat that with multiple strips at various angles, maybe stuck to a cylinder? Sorry, all of this is a bit of a repeat of above, but I kind of laid out everything I know up there so,.. :-(

[@Eeu94]

​@@poneill65 Thanks for the answer . My uv lamps are 3, they are lamps that are used to paste glass films on cell phones with a curved screen. My product is 40 volumes.

[@johntimbrell]

I also liked the obvious previous preparation that went into the making of the video showing that the presenter had come up against problems and overcome them and then explained the necessary precautions in the video. What a refreshing change. Of course this new to me process, caused more questions than answers which I researched to find this - - For yellowing, there is a technique called retr0brite that has proven successful, and essentially involves using MORE UV light to break apart the bromine-oxygen bonds. Hydrogen peroxide is then used to get in there and fill the broken bonds with hydrogen, making the bromine more stable and reversing the yellowing

[@eatmenickers6238]

Thank you! This is exactly what I was looking for!

[@OgbondSandvol]

I've done some research, too, and I found a lot of sources that says that the understanding that the yellowing is caused by bromine flame retardants is a very common misconception introduced by Nintendo.

This is, single-handedly, the best video on the subject. Period

[@gustavo_vanni]

7:23 I think you put the aluminum foil backwards. The reflective surface is facing outside of your container. The way you put it, it's still reflecting some UV light, but less. And it's worth to mention that some containers are not "transparent" to UV light, so that's another thing to keep an eye on when buying. A simple test to know if the container is transparent to UV light is to put something that's reflective to UV light inside and see if it "lights up" when you turn the UV led strip on. Love your channel, keep doing these things!!

[@stephenphillips7642]

I believe you mean "reactive" such as fluorescent or phosphorescent materials? This could be used to gauge how much UV light is absorbed to by placing the material directly in the light first then afterward outside the container. Unfortunately you are correct that, most plastics absorb (or block) UV (400nm to 10nm is UV but UV has 4 bands in it) however not UV-A which is the spectra specifically of interest for this reaction. Well actually violet to LOW UV is another way to say it. 450nm to 300 nm range. So LEDs of the 395nm and 385nm range would work as well as LED's (called Royal Blue) from the 450+ range.

[@ms-dosman7722]

In my experience you'll notice slight re-yellowing in about 6 months after you've treated it with the hydro peroxide. But that's also dependant on the place you store the items. Best is to keep them out of the sunlight and in a cool place. The things I have retrobrighted (retrobritten?) last summer are noticeably yellowed now. I expect I'd have to redo them every 2 to 3 years to keep them from going back to a yellowed state that I would consider bad enough to take them apart again. This technique only reverts the yellowing for the top layer of the ABS plastics, underneath the chemical reaction is still going.

[@primusoriginal8648]

@@ms-dosman7722 Have you tried to use a non-grease anti-dust UV resistant protection?

[@ms-dosman7722]

@@primusoriginal8648 No, neither have I heard of such a thing. It sounds interesting, although I can image that you'd have to reapply this spray regularly to keep it working. Next to UV, heat is also a factor in the yellowing process. I have a kitchen appliance made of ABS plastics in the cupboard above my oven. This thing never sees any sun light but the heat from the oven is making it yellow still. So UV protection is only half of your worries.

[@Ea-Nasir_Copper_Co]

F D This won't remove yellowing from exposure to tobacco smoke. The normal yellowing of plastic consoles, appliances, etc. isn't primarily caused by smoke, although a layer of smoke on top of yellowing plastic will (as you unfortunately found) make things much worse. The yellowing you see in most old plastics is the result of brominated flame retardants in ABS plastics used for game consoles, computers and components, small kitchen and bathroom appliances, synthetic fabrics, and even household paint. As the plastic ages the bromines destabilize and migrate to the surface; this happens faster if the plastic is exposed to UV rays, either from indoor lights or the sun. (This is why all other things being equal, the top surfaces of consoles are often darker.) The H2O2 and UV light remove the free bromines at or very near to the surface, which whitens the plastic until more bromines migrate to the surface. (Edited for typo.) By the way, if you ever have a piece of plastic you can't soak, go to your local beauty supply store (like Sally Beauty in Canada/US) and buy what's called 40 volume creme developer. It's 12% H2O2 in a cream format, which can be painted onto surfaces. Cost: $2.89 here in Canada for a small bottle.

[@andy86i]

the myth that yellowing to plastics is caused by cigarette smoke is a very old and untrue one. its the bromine in the plastic reacting with heat and light.

Use a glass container like an aquarium rather than a plastic container for the H2O2 bath. “Clear” plastic absorbs much of the UV light, glass will absorb less so the process will speed up. Try Goodwill for an old aquarium.

can you reuse the H2O2 for the next de-yellowing project?

[@darioferaudo8805]

I would like to know too!!!😃👍

[@Wastelander1972]

The solution is used to degrade organic solutions in aqueous material, so I would say no to stay on the safe side. Idk- I don’t know enough about hydrogen peroxide’s reaction or decay in UV light enough to say for certain.

[@jaedenamadeussalim2438]

I dont think so, I read that for storage instruction for H2O2: avoid light, because the H2O2 will turn to water Thats why they came in drk bottles

Dammmnnn! I have a piece of plastic on a drilling machine I would like to restore, it’s now 22h20 and I am like, is there not a store open NOW so I can use this life hack! Thanks for the vid! 😱

[@abhainnwright164]

Can you reuse the H2O2 after the process is complete or do you need to dispose of it and purchase a new jug for the next time?

[@Mardy72]

I was wondering the same thing

[@bumbledouche3323]

You need to dispose of it, as it will become effectively useless. The UV accelerates the decomposition of H2O2, causing it to release oxygen. That free oxygen then oxidizes the colourised components, lightening the discoloration. As this process is liberating oxygen out of your solution, it becomes progressively weaker until it eventually reverts to a much more stable molecule, H2O - water.

Outstanding! Thank you for sharing the process! Question: can you use the same hydrogen peroxide several times? Thank you.

[@DeathNeos]

I am also interested in this

[@CaptainSunFlare]

No. Another commenter explained why in another comment as follows: UV lights cause the H2O2 to decay into water H20 and the free oxygen atoms oxygenation of the plastics makes it light again

[@lorijames3974]

Yes, that’s why hydrogen peroxide is sold in dark brown bottles because any light degrades it.

[@AlexandeRSciswoR]

@@lorijames3974 I didn't know that! I thought it was more of visual decision than a chemistry decision to use the brown bottles.

[@pedroamares8464]

Thanks for the vid! If I may, it would be great if in future videos you could explain why things happened (like why did the plastic turn yellow over time) and why you are doing what you are doing (why UV lights, why hydrogen peroxide, why both together, what is happening there) like you did with the laser. Not sure if this is too complicated for the KZbin format, but still. Keep them coming :D

[@johnny_phouc_21]

Pedro Amares it was explained dipshit

[@FinnickH]

@@johnny_phouc_21 I'm pretty sure the person was referring to the actual chemistry behind this process such as the chemical reactions with UV light and hydrogen peroxide or the detailed explanation of why plastic turns yellow in the first place. What was explained in the video was mostly about physics, not chemistry. It's enough to understand how it works to be able to replicate the process but some people like to learn more about the way things work in life, you should probably try that one day.

[@Jotdotcom]

Very clear video thank you! Do you find the brightened plastic parts stay bright or do they degrade faster than they originally did?

That Dreamcast needed to be in the solution for a few more days. You can really see it when you place the controller next to it. Thanks for sharing your knowledge.

[@Wastelander1972]

I noticed that too... it needed a bit more time but still way better than what it was originally.

[@spokehedz]

I would use the LED's taped to the inside of a container, and then put another container inside that--pressing the LED's up against the inside of the bucket. Since there is tape on the back of the LED's, and you are not modifying anything about the bucket, you could swap them in and out easier...

[@Pingoinnn]

Ah yes good idea ! But how do you do with the LEDs that are on top ? Tape the LEDs to the lid of the container ?

[@spokehedz]

@@Pingoinnn A lid might have the extremely low risk of concentrating hydrogen, which isn't a good idea. I am not sure you would need to have the top ones, if you went high enough up the sides.

Fascinating to watch you work, thank you so much for sharing! ❤ My problem currently is the decorative plastic front panels on the two doors of my 1975 Austinsuite wardrobe and the drawer fronts to the matching dressing table and chest of drawers.

Could you explain if the percentage of H2O2 influences the speed or the final result of the process? Here in Brazil we can buy from various percentages, from 3 to 50%. And once used, do we discard it or can we reuse it? Great video, thanks for the tip.

[@hausofluzon]

Even i also wanted to know that can that used up solution of H²O² can be reused or not?

[@lesiliegreer1257]

Used h2o2 loses an oxygen, making it h2o aka water. It will for sure be a lower percentage of h2o2 after, but if it potentially could have a little life left in it, bht it may just be mostly water

one thing that would be perfect that I wanted you to do was recover papers, manuals, books, etc. But recovering their normal color by removing the yellow that remains on the paper, I saw a person doing this, but that person insisted on not saying it, as if it were something original of him. How would you do that and show what you used?

[@zgredek1234567]

I guess with UV light alone? Will take a long time but should do the job

[@koyurofox]

@@zgredek1234567 Does it really work with paper too?

[@felixgeraldo966]

Note that he said in this vid, retro brightening brings the temperature up to 70degrees so i don't think this is good on papers.

[@FinnickH]

@@koyurofox I live in a very warm place where the sun is very strong and it's extremely good to remove stains and yellowness on plastic but here we know never to put prints, paintings etc in during sunlight because they will fade very easily. The ink on paper and paint on canvases just lose their pigments extremely fast (a matter of weeks or months instead of years) when in direct sunlight here, so I'm not sure it would be such a good idea but if you have a UV lamp you could try with paper you don't care about and see if the ink is affected! The climate here is very particular so it might be due to something else, or a combination of things, so I think you should give it a try but seeing what sunlight does to ink here, you probably shouldn't try it with something valuable 😅

[@hlebo]

You've done a great job of demonstrating the "wet" method to reverse yellowing. But there are times when yellowed plastic cannot be separated from electronic components. Would you be willing to try a second demonstration that shows the "dry" method that you mention in this video? You said it could take days to work, but that's ok -- if it works!

[@Odd_Experiments]

I might do a a video where I test some other methods

[@hlebo]

@@Odd_Experiments That would be great. A dry method would be especially useful for tech dummies (like me) who have precious vintage technology, but aren't smart enough to take it apart without wrecking it!

[@petergresham8913]

I have restored plastic wrapped particleboard that wouldn’t take this type of wet treatment with hydrogen peroxide gel sold at hair dressers and sunlight is much more intense than led lights. It only takes 20mins using the sun. The trick is to wrap the part in glad wrap to stop the gel drying out and use reflectors to bathe the part evenly in sunlight.

@@petergresham8913 Sounds great; I'll see if I can paint it on carefully!

[@leguy9396]

Please correct me if I'm wrong for this application but by doing previous in-depth research on indoor growing operations, I learned that aluminum foil is very inefficient for reflecting light, and rather reflects heat thus creating heat spots. It might be different since the reflection is through plastic but either way, mylar would be a far superior material to use for efficient and even light reflection.

Brilliant! I didn't know this restoration was possible. Looks like a great way of extending product life rather than chucking it away and replacing it. How long does the renewed whiteness last? - does it eventually go yellow again?

[@Dave01Rhodes]

Since the yellowing is usually caused by sunlight, if you keep the restored plastic out of sunlight, it shouldn’t yellow again. Some people say if you spray the plastic with Armor-All, it prevents the reaction from occurring even in sunlight.

I guess this should work really well for clear phone cases as well? They tend to turn Yellow.
