Do you want to restore your yellow plastics back to their original glory? If so, keep watching!
In this video we'll be restoring yellowed plastics back to their original color.
Restoring yellowed plastics is sometimes known as Retro brighting, as it's usually retro items which have become discolored, and we want to brighten them up again.
Retrobriting is a hot topic of debate, but the truth is, very few people have done proper testing on this subject matter, especially observing the results over long periods of time.
I did a lot of experimenting in this video and learned a lot along the way. I have shared some of this experimenting as well as my mistakes so that we can learn from this together.
In this video we'll be discussing:
- Why this happens
- What types of plastics will this work on?
- How to actually restore the plastics (The process)
- Something I learned and tried along the way.
- How long will this process last?
All with a primary aim of: making the process easy and also keeping things cheap and accessible.
- Hydrogen peroxide counteracts the oxidization, because it itself is an oxidizer (an oxidizing agent!). Hydrogen peroxide is one of the best oxidizing agents known to man!
- The UV light converts the hydrogen peroxide into highly reactive hydroxyl radicals, which then decompose the problematic substances.
[UV Light Wavelengths]
UVC - 200-280nm (Shortest wavelength. Classed as dangerous rays. These don't penetrate the earths ozone layer.)
UVB - 280-315nm (Mid wavelength. Causes sunburn and skin cancer etc. Classed as burning rays.)
UVA (Longest wavelength - Reaches deep inside tissue and skin, causing aging. Classed as tanning rays)
315-350nm - Uses to cure polymers. Used in printers and some tanning equipment
350-270nm - Blacklight. For bug attraction, sun tanning. etc.
370-400nm - Blacklight blue (BLB). Glow in the dark lighting. Bank note forgery checkers.

Basically, you go to a beauty supply shop and ask for hydrogen peroxide cream. It's like, 40% H202, not 3% like the regular stuff in a bottle. Anyway, take the plastic apart and paint it with a thick (but even!) coat of the cream, then cover with plastic wrap to keep it from drying out. Place in a sunny area for up to 24 hours. Wash and check, repeating if necessary.

[@TutorialGenius]

It's open if you have a bit more $$$... But it's more harsh and can leaves streaks

[@zachfutv9986]

Accept cream is a pain in the butt cuz it doesn't un yellow it evenly so you have to do the whole process a few times.

[@leschen9725]

[@garymummert3945]

I bought a vintage 1970s/80s pair of Porche design model 5600 ski goggles that are yellowing. I'd like to restore them but want to protect the non-plastic parts if necessary. Will hydrogen peroxide harm ski goggle lens, especially the uv coating & the foam that rests against the skin while using them and the rubberized Velcro straps if the entire goggles are submerged in it? Do you use straight peroxide or dilute it with water? I may have missed that in the video.

[@TutorialGenius]

It has potential to harm the lens, yes. It's probably a good idea to remove it, or do a spot test (Just like when dying hair) As for the comment: "Do you use straight peroxide or dilute it with water?" - You should watch the video all of the way through, I already covered this part :)

[@gdelete8098]

Thanks for sharing your experiments and expertise. Do you know if this process will make the plastic more brittle than before? Thanks.

[@TutorialGenius]

In my experience with 3%, no it hasn't made anything more brittle then before. I tested this with some yellowed see-though plastic from cardboard kids toys (Like the Good Guys doll from the 80s). I can't say it made it any more brittle than before, but I used that as an example because this plastic is very thin and more fragile than a Dreamcast or a NES case for example. An oxidized piece of plastic, is in itself, more brittle (As heat for example) weakens the plastic. So it's already somewhat brittle before we begin. Perhaps people are blaming the process for an already fragile item. But, I have not tested the effects with a high strength H2O2 solution, perhaps that could yield different results as it would give off more heat (amongst other things), especially when in an enclosed area (Indoors with UV lamps.). Most videos I've seen use a 12% solution, so that could be responsible for this talk on brittleness.

[@gdelete8098]

Thank you@@TutorialGenius

[@SlikWilly-gx1bz]

peroxide does weaken plastics, just realized after I stepped on a plastic I've stepped on before only difference 3% was used recently and crumbled the plastic which before didn't budge. this does explain cracked plastics of the past 🤔 🙉

[@WhiteFalconus]

Nice to see the good old Sun is still the way to go. Have you tried fixing the overbrighted NES? I have an old Amiga mouse I managed to overbright and its now sporting some white smudges. Is there really any way to get rid of them?

[@TutorialGenius]

Yes I tried, after a couple of goes, it cleared up a bit :) I think its of trial and error. It helps when the sun it directly above to prevent shadows and whatnot! I had some trouble doing this in the winter haha!

[@WhiteFalconus]

@@TutorialGenius I can imagine, I just managed to buy 3L of 5% peroxide and waiting for sunny days to come in a few months :) I know it needs to be moved around every hour or so, I just wondered if a botched job can still be saved somehow, to get rid of the white smudges. But I guess the only way would be to make it all white which would look bad. Probably no way to get them darken back a bit.

[@mattfrommo2483]

I have an action figure with sun damage. If I follow this procedure, will it bleech the non-white colors on the figure?

[@TutorialGenius]

Give it a try, let us know how it goes

[@chardibinx]

Use hair dresser peroxide instead. It’s a paste and doesn’t need to be submerged, just wrapped in cling film and left in the sun.

[@TutorialGenius]

That paste kinda leaves smearing marks, its not too great to be honest. It's also more expensive

[@riffrock2024]

Did the logo on the Dreamcast top get discolored?

[@TutorialGenius]

No it didn't! :)

[@AkubraHatman]

Can you treat plastic by wiping the plastic with a Hydrogen Peroxide soaked rag instead of soaking it in a tub?

[@TutorialGenius]

How will the catalyst (sun) access to component if it's covered in a rag?

[@casualtrips9571]

Have you tried the no contact vapor method?

[@TutorialGenius]

I haven't, but if you have the $$$ for the food grade H2O2 and large clear container, I'd probably go for it! Looks like a good method to use also!

[@casualtrips9571]

@@TutorialGenius it's only like 14$ for some food grade 12% on Amazon so I'll def try it

[@SovereignKnight74]

Can we get an update? Did any of the items start to re yellow faster?

[@TutorialGenius]

Actually there are all still doing great. They have been pretty much kept in a dark place, so the reaction will reverse very slowly without a catalyst 🌱☀️

[@SovereignKnight74]

@@TutorialGenius Glad to hear. I'm dealing with this issue with Hasbro products. A lot of their new Transformers figures are rapidly yellowing for some reason, and it's a huge problem currently. I'm trying to retrobright some right now to see if the yellow comes back.

[@naggano]

Can the peroxide be used multiple times or just once?

[@TutorialGenius]

I kinda covered this in the video already! That's why the video is so long haha!

I'm searching for a hydrogen peroxide and from what I see the 12% solution is not more expensive at all than the 3% solution (weird)

i bought 35% without knowing how volatile it is.

oww yeah thats a bit too strong unless you have something tough you don't care too much about
