Whitening yellowed toys with Hydrogen Peroxide

[snaketales]

I've got Groove covered in peroxide sitting out in the sun in my work's front garden... hey, if I'm stuck here all day I may as well do something useful :D

[kup]

It will be interesting to know if non Headmaster/Targetmaster toys from 1987 are more compatible with the H2O2.

I have tried at least one toy from 1984, 85, 86, 88 and 89 toys with varied success. Only the 1987 TM/HM toys I can confirm to be incompatible with the liquid form of H2O2.

[1AZRAEL1]

I'll be testing my Slugslinger and Triggerhappy tomorrow, hopefully there will be some sun for it to work.

Will post some some before and after pics tomorrow when I get started on it. I am interested to see what happens.

[bowspearer]

I'm going down a slightly different road and trying retrobright on a
USS Flagg. Once I've bought glycerine, xanthan gum and oxy-action washing power in a few weeks (picked up the H2O2 today), I'll let you guys know how it turns out. Figure it should be handy in terms of the big projects that some of us might have.

[Cat]

I've been tempted to try this.

I've had my teeth professionally whitened, the expensive (and painful, it really burned) way.

I have touch-up paste, which is much stronger than your store stuff.

I've been tempted to see how well that works, and when I go to the dentist next to get it redone, to get a figure part done at the same time, to test both methods.

[1AZRAEL1]

Testing it out on Slugslinger, hopefully there is enough sun to actually do anything.

[1AZRAEL1]

Early testing seems to be going well. Sadly the sun was not around for long enough to do a full test, but it looks promising.

Sadly I can't give any pictures or more result until next weekend when I am off. Saturday morning I will get up and do it right away and hope that there is sun about :p

I had it outside for maybe 3 hours with this stuff on, and there is a change in the discolouring, without any real damage to the plastic that I can see. It still looks as shiny as the discoloured parts. So maybe this could work? Further testing needs to happen before I can give a clearer analysis. (also have to pick up a brush to apply it better)

Sit tight, more to come next weekend.

[snaketales]

Gave Groove his time in the sun today (about five hours) with creme peroxide, with good results.

The amount of whitening seems to be dependent on the amount applied, as his de-colouring isn't consistent. At this stage I'd say you can't put enough of the stuff on.

Alas we have now been forecast 4-5 days of rain.

where the heck do you get glycerine and xanthan gum?
i've been looking for those two ingredients to make my own retr0brite for ages now but have had no luck in finding them.

i opted out for the 12%/40vol peroxide cream from price attack at $10 per bottle for 950ml. it seemed cheaper and lot less less troublesome than H202 + glycerine + xanthan gum + oxy-action washing power. isnt it?

[snaketales]

No before pics but here's some after shots

http://i54.tinypic.com/mj8jue.jpg

http://i56.tinypic.com/1zd6aae.jpg

These were yellow/brown spares... I'm thinking of swapping them into the main collection now.

Here's a before shot of Inferno's ladder. You should be able to see a clear line between the white and yellowing plastic

http://i51.tinypic.com/30ib03b.jpg

[snaketales]

...and here's the ladder after. Much, much better.. so much so that I couldn't tell which side I had originally photographed! It's a bit patchy, so I suppose being immersed in a liquid would overcome that.

http://i52.tinypic.com/ztdfkh.jpg

http://i54.tinypic.com/33fcftf.jpg

I also gave junker/spare Drag Strip and Breakdown a go. Breakdown does look a bit creamy but I couldn't tell any dfference with Drag Strip (altho it wasn't bad to begin with).

I'e also noticed a couple of patches of dead/white skin on the tips of my forefingers, so be careful!

[VERT]

Yeah I had Joker hands when I was doing it. They all look great. I should give my Firstaid a go too :)

[bowspearer]

where the heck do you get glycerine

Chemists


and xanthan gum?

health food shop

Possibly, but I'm restoring a GIJOE USS flagg, so it's too big for liquid.

Yeah, I've already bought a set of rubber gloves for when I mix up retrobright and apply it, as that's something the wiki warns you about with handling hydrogen peroxide.

[bruticus]

Possibly, but I'm restoring a GIJOE USS flagg, so it's too big for liquid.

huh? i was referring to the peroxide "cream" (not the liquid H202 bath method). Cos the peroxide "cream" from price attack should essentially be the same as retr0brite paste, except this is already premade.

anyways, interested to see how you fair with the USS flagg whichever way you end up going.

Snaketales - Man thats one yellowed ladder. glad to see it revitalised so much! also, were the wheels on firstaid rusty before you treated it with peroxide?

[Aqua Prime]

Can anyone tell me if the creme peroxide affects stickers at all?

[snaketales]

Snaketales - Man thats one yellowed ladder. glad to see it revitalised so much! also, were the wheels on firstaid rusty before you treated it with peroxide?

Yeah, the wheels were like that when I got hold of that figure. The rusting wasn't from the creme peroxide, if that's what you're worried about.

[1AZRAEL1]

Can anyone tell me if the creme peroxide affects stickers at all?

Another thing I can test for you tomorrow. I assume it will, but I will see what happens.

[1AZRAEL1]

Well I have had some success with this miracle cream. Works fairly well on Slugslinger without any real damage to the plastic. I left them out in the sun for 3 hours, cleaned them off and reapplied for another 1 and half hours. Sunlight started to fade.

http://img.photobucket.com/albums/v502/1AZRAEL1/After3.jpg

What you can maybe see in the last picture is there is some streaking on the plastic, which could be from not applying the cream evenly. I used a brush. I am going to test using a sponge to try apply evenly onto another piece to test.

The purple on the sticker was affected, but strangely not the rest of it.

I think the grey plastic worked better because I caked on the cream more thickly than on the blue bit. All things I will look into more detail tomorrow.

One other fun fact that we could use this cream for is rusted screws/metal. The screw in the foot seemed to clear up using it. Pity I didn't take photos of that before I did it. Another thing to test tomorrow.

So testing for tomorrow will be:

- more on the foot to see if I can make it lighter still, it was pretty bad to begin with
- test another blue piece
- put some on a rusted screw to see those effects better
- use a sponge to apply cream and more thicker
- earlier to get a better start on testing for more light

[Aqua Prime]

Good to see it worked great ok 1AZRAEL1

I tested the Creme Peroxide on another '87 Transformer, Rippersnapper. I didn't take any photos but he came up great. No issues at all.

I use a thick decent paintbrush and coat it on nice and evenly. No issues with applying it on his stickers either.

Up for test next is '90's "reissue" Classics First Aid.

[snaketales]

I did an aerialbot Slingshot nosecone and two of my three original Transformers toys - Fireflight and Blades - today and they came up great with no problems.

I was careful around the stickers but noticed when I was wiping the creme off the red came off the Autobot symbols on Fireflight's wings. These are the original stickers so it may well just have been age. I didn't notice any appreciable change to the other stickers (altho they are 20+ years old and a bit tatty to begin with).

[1AZRAEL1]

Stickers are a funny thing. Best avoid getting any on them I'd say.

A thicker application worked better. No streaks on the blue parts at all. It is still a deeper blue when compared to a non yellowed part, but it looks much better than a greeney blue. I will put more on it next weekend to see if I can lighten it further.

The grey foot is getting lighter still, and is near bringing it back to it's original colour. Again, more coating next weekend.

The screw is still rusted, but it did remove some of the rusting.

But great news is the fact it is not destroying the plastic like H2O2 does. Hardest part will be trying to do it evenly when you have to do more than one coat. But the great thing is it takes a few hours, so you can wipe it off and check it every so often, and reapply the cream.

Hey dude, just out of curiosity; Do you think that if you were to put the solution into a spray bottle that that would give you a more even coat than using a paint brush?

[1AZRAEL1]

Possible. I can give that a shot next week. Just as long as I put a thick coat all over, doesn't have to be perfect, just as long as it all will be well covered.

Yeah, I just thought that if you were able to spray it on, that it would give you a more even and consistent spread than having to try and do it with a paint brush - Fingers crossed for you anyway man. ;):)

[loophole]

what about mixing the cream with the bottled stuff to give a stronger solution thats what ive been thinking of doing

[1AZRAEL1]

Good thought, but I think the liquid seems to have an adverse effect on the 87 Targetmasters, but the cream seems to work well. Maybe I could pick up a stronger cream, pretty sure I saw one that was stronger.

[Aqua Prime]

Here's a couple of my before and after shots, both featuring 1987 Transformers.

*does a crazy coles TV ad.. Ta da*

I forgot to add, that was using 12% Creme Peroxide *thumbs up*

[kup]

That Weirdwolf looks fantastic!

Looks like we may have a proven solution for 1987 yellowed toys! To be sure, it would be good if we could do something like a Slugslinger who is very prone to yellowing and highly negative reacting when it comes to liquid H2O2.

That's where the foot and blue parts I have been working on have come from.

The blue is somewhat darker than the normal blue, and the grey is still slightly yellowed. They need another treatment to see if I can get them closer to perfect. But so far so good. I haven't taken an shots of the next phase of treatment yet. I will be doing more this weekend.

[Aqua Prime]

So far I haven't had any luck with my "Classic" First Aid with the Creme Peroxide. I think I might have to bite the bullet and throw him into a Peroxide Solution.

Just recieved a Gnaw, so we'll see how he shapes up with some Peroxide love when I start holidays and we get some sunshine :)

[snaketales]

I tried some creme peroxide on my g1 Triggerhappy today... no joy. :(:confused:
I wonder if the creme has lost its potency? More testing required....

[Aqua Prime]

I concur. I've attempted the creme on Triggerhappy around 3 times and no joy. Likewise with my "Classic" "reissue" First Aid. I have a junker Triggerhappy I can try using a peroxide solution on, but I'm still kind of annoyed his colour hasn't even budged considering how well it worked on Weirdwolf using the creme.

My brother has also used the creme on Highbrow and he came up spectacular. So Headmasters appear to be fine but Targetmasters, not so.

[Cat]

I've got a touch-up tube of proper dental strength stuff, from when I got my teeth professionally whitened.

I've still yet to try it on any yellowed figures though.

Hmm.

No soaking for me. I covered the wings nice and thick with the cream. :D

I did a getaway and a searchlight today with the paste.

Getaway ended up a bit streaky so he needs round 2 but searchlight(well I only did the back) came out very well. :cool:

Unfortunatly he stayed exactly the same - they grey wings have yellowed badly.

[1AZRAEL1]

How many doses did you do? I noticed with Slugslinger that it takes a few doses to really get him looking better. I haven't done it in a while, I might give him some more doses on my days off next week.

What a great forum discussion on the flow learning as I go..
I have been meaning to whiten some Jetfire parts that I needed to replace the engine plate attachment.
I have one main concern that need answering from experts.. If I whiten the parts.. will they change back to yellow color later on even if my Jetfire is also sheltered away from exposed sunlight on a display cabinet.
Are there records that some one have whiten their Jetfire parts and observed the color result after the 6% "HP whitening method" after a few weeks or months to see if the color stayed the same with no changes.
Let me know before I attempt to run off to the chemist with my request :) :D

Whitening the plastic will not prevent it from yellowing in the future. What the Peroxide does is basically 'reset' the plastic back to it's original state (or near as it's not always 100%) but does not prevent the yellowing from re-occurring as it previously did.

Once you whiten up your Jetfire, you should keep it in an area shaded away from direct sunlight and any source of UV rays like direct light bulb light or fluorescent light. It is never 100% but it will certainly help in preventing the plastic from yellowing again as you would be keeping it away from the direct causes.

Thanks for the tip off Kup

At this stage I am disassembling a whole yellow stained Jetfire and placing metals and plastic in separate sections.
I should take pictures of parts before and after during the experiment and see how they turn out for better or worst and post them up on this forum discussion later.
Bring out the hot blazing sun with a brush on my hand and a bottle containing 12% creme peroxide on the other hand haha :D:D

[1AZRAEL1]

Bring out the hot blazing sun

What sun? :p

[Danzvader78]

What sun? :p

Haha.. Took me four attempts to whiten my Jetfire parts out in the sun in different times this week.
Am pleased with the whitening results so far. I even dabbed on H2O2 on my old Star Wars Leia and Stormtrooper action figure while they baked in along with parts.
The results was amazing.. From heavy stained yellow to sparkling white within hours.
My partner told me that yellowing is common in white action figures because they were exposed from smoking chemical lingering inside the house and also sun damage as well although smoke exposure is more common too

Congratulations! Jetfire is one of the more H2O2 friendly toys but just keep in mind that some plastics don't react well to it. We have identified most of the Headmaster/Targetmaster 1987 figures as vulnerable.

Thanks Kup.. It would not been for you if I did not know what to do something about the stained Jetfire
I want to know to confirm if all of the 1987 model toys are vulnerable to H2O2 especially Fortress Maxiums?

[Slag]

. All they had at the store was 12% peroxide creme. I'm trying to paint the creme on a scourge now. fingers crossed

[VERT]

I have done a scourge and it works :D

[Slag]

I have done a scourge and it works :D

Sweet. What about the different degrees of yellow. can it be whitened too much.. could it work on clear toys as well . e.g. jewel lord diamon/solitaire

[Slag]

it's working. i probably spread it on a bit thin 1st time round so extra thick today. didn't know whether or not to take the old stuff off 1st so i've gone 50/50

[VERT]

I just put it on thick. Not sure about clear plastic yet.

[Slag]

I just put it on thick. Not sure about clear plastic yet.

Yeah that's what i shoulda done first. just got back and looks like it's close. 1 more dose tommorow should do it. and i'll try and find a test subject with the clear issue.

[liegeprime]

Well, Ive finished dosing a Scourge with the 12% Peroxide Creme and it took about a week. I applied not so thick though, and it's been raining that week so prolly why it took that long. Although he didnt turn out clear light, light blue instead there are some parts which are lighter for some reason , oh well, dunno what went wrong but it's not so immediately noticeable.

So each time did you remove the existing cream and apply new stuff,
Paint over the old cream with new cream or just do one coat and subject it to the sun for a week.? I'm doing a piranacon chest shield also and thats working a treat.

[Darthprimus]

you didn't by any chance do a before and after pic? id be interested in seeing the difference.

[Slag]

Really sorry, wish i had.. scourges come up good after 3 or 4 days in the sun. (but my backyard only gets full sun for a couple of hours) superion worked well after one day. pirahnacon probably 2 days. Jewel lord diamon -no effect. (at least it didn't melt)
Fingers whitened within minutes. tell-tail signs, severe burning sensation.

Actually one of the scourges is in the sales thread . Omega supremes g1/g2 lot. page 2 atm. And the silverbolt tail fin too.

here's pics. You can see what the piranacon shield was like.. looks like i missed a spot. (pics on the stickers wiped off)
. Going to blast the scourge wings again. you can see the indentation line is actually bluer then the rest of the affected area. i can only think that more of the cream stuck in that area or didn't dry out as quick in the sun. nearly passable.
superion shield was not bad but did it anyway. you can see the slight diff between front and back.
not sure about abominus head. i kinda like how it yellowed. but if it gets a treatment this is the before pic.

[Slag]

here is the abominus head after 1 day. (Full sun to back of head, sides tomorrow) i went too far with the piranacon chest shield.

sorry late reply- I applied a good coating and after 2 days - since it looks like it's dried a bit Id wash it off - pat dry it then apply another coat and do the same process. I wasnt able or rather couldnt be bothered to take before and after pics coz I had a friend from overseas staying over so at best the attention it got from me was every 2 days or so of changing the coats. Playing host for 2 weeks to tourists is tiring hehehe :D

[Slag]

I bet. :D I'm just winging it atm. i'd like to try the jar/liquid technique . that way it wouldn't dry. might even help with light refracting?. I'm finding i gotta do 1 side at a time this way. good for keeping stickers on though..

[liegeprime]

Well you have to look for big mouthed jars and also preferably with a glass lid, that way the lid wont cause any shadow - there's some available at Reject Shop or some of those Homeware shops managed by Korean ladies:) - cheap too! Make sure it's a good seal otherwise it'll evaporate. Youll need a heckavalot of H2O2 liquid for it though....

[Ravagecat]

Okay I thought I would give this a go. First up was G1 Whirl with 6%Peroxide been two days and is working but so slow. Next up I got a one ltr bottle of 12% Creme Peroxide from (Price attack?) Lots of Hair products (was my wifes idea to look at that place)

I used it on my G1 Getaway. Painted it on thick with a brush and left him out in the sun all day. It worked great and he is as white as he was when he was new. No damage has been done to the figure. Total success. Will try it on the Whirl tomorow I think.

Hi guys,
some great findings on this topic, just like to say thanks to everyone that has contributed their findings. A lot of my (purchased white) transformers are yellowing all of a sudden with no exposure that I am aware of to the sun which is very dis-heartening to say the least.

I wanted to try the peroxide cream on my getaway but had some questions for Vert if he is still using this site.

1. Did you dis-assemble your Getaway and only put the affected parts in the sun?
2. Did you cover up the blue parts and windshield (I am paranoid that exposing these parts to the sun un-necessarily will damage them too)?
3. Did you just paint around the stickers or remove them first using the zippo fluid technique?

Any thing you can tell me would be great. Thanks...

Also what do you guys do with the removed stickers while whitening the toy. Put it on a used sticker sheet backing or something?
Has anyone NOT had their toy return to yellow after using any of the peroxide processes?

Thanks in advance...

[liegeprime]

Well, as for stickers, since my G1's are basically old old and not as pristine as Heroics's figures are, the stickers tend to be quite dilapidated and old so once I peel em I just get reprolabels instead. It actually makes the figure look better after the revitilizing bleaching bath - almost like new.

As for figures going yellow again, sadly it does, as to how long before it does it again not sure, my Actionmaster megatron is yellowy/ish again after about a year post the bath but Im reluctant to dip him again coz I dont have replacement stickies for his chest symbol, and plus the other painted parts are faded already from the previous bathing. Im kinda lazy so I didnt bother to disassemble the figure first - it's too small.

[theshape]

Hey guys , I just read through this whole thread. I was wondering what you guys thought about using 50% hydrogen peroxide ( I can order this from a chemical wholesaler via my pharmacy). Would this be too strong?

Also, is dabbing on peroxide cream quite effective? Do you need sunlight to activate it? Cheers

[VERT]

Cream works great for me. Yeah sun really does help it to work

[1orion2many]

I found the peroxide cream left streaks as it's hard to get it even:(

[VERT]

Have to drown it in the cream like its been slimmed to avoid that. Well thats how I do it anyway

Used it on some Scourge figures and well you still need sunlight but not as full on, I got that streaking that orion mentioned in one, but not on the other and well, I do find it better for smaller figures coz then I dont need to dissasemble it just so I can dab the part I needed bleached using a cotton bud. I apply 2 -3 layers actually, I let the first application dry a bit then add 1 more then another, after 2 days I was it away and re apply again 3x , after 3 days and it doesnt look like it's improving that when I stop. It means it can't get no whiter than that is how I interpret it.

As for the 50% H2O2 hmmm could be a bit too strong, we must use it with caution, prolly use it on a yellowed junker to test it first and be careful as it is going to be corrosive as on the skin, wear goggles and gloves plus long sleeves to be sure.

Remember how I restored the white on my Vroom? I had him completely away from light at the back of a bottom shelf but sadly, he has gone yellow again!

He did last for about a year and a half though. The yellowing is fairly recent and rather sudden.

Hey Kup - I'm interested to know why it has changed back...

We know that there are a bunch of things that cause the issue in the first place like sunlight, smoke, heat, bad plastic batch, even the type of light bulb you have can cause issues for some plastics.

Do you use a fluorescent bulb in your toy room, old school tungsten screw in, led down light etc. ?
Is the room exposed to a lot of dust ?
Is the room exposed to natural light ?
Does the room get hot during the day ?

I have whitened my getway and searchlight by applying the peroxide paste and want to try and avoid them going yellow again.

Thanks in advance :cool:

[kup]

Do you use a fluorescent bulb in your toy room, old school tungsten screw in, led down light etc. ?
No, the Toy room is kept in constant darkness: No Sunlight and a low density globe is used only occasionally when I go in after dark to look for something. As mentioned, despite the room kept in constant darkness, the toy was completely away from direct light at the very back of a deep mid-bottom shelf (You need to lean down and look in to see it)


Is the room exposed to a lot of dust ?
No, I am the only person living at my place and no pets. The toy room is also not a 'living area', I only go in to take things in or out so minimal dust.


Is the room exposed to natural light ?
Not at all. Blinds are constantly closed and any gaps barricaded by MOTUC mailer boxes.


Does the room get hot during the day ?
Not at all. Overall my place is fairly cool.


Just to mention that it actually took two years to yellow again (wow I didn't realize it had been that long!), it wasn't a sudden thing.


That's why the whole thing seems strange to me. The toy had been kept in constant darkness ever since I whitened it. My guess is that although sunlight (artificial light) may expedite the process, yellowing can occur despite of it just for being exposed to air.

As we know, some plastics are more prone to yellowing than others so maybe some will mostly be affected by sunlight while others just need to be exposed to air to yellow.

[liegeprime]

hmmm must be a bad batch kup. My Vroom hasnt yellowed (knock on wood) yet or at all actually. Although my downshift figure could use a creme treatment, it's not pristine white as it should anymore.

[Trent]

Or the whitening process is just temporary. Once it has yellowed once then it is more prone to doing so again.

Thanks for the reply Kup....It would seem what you are both saying makes sense. Some plastics (especially if the batch was not quite right) are prone to yellowing with age due to exposure to just air :eek:

Frustratingly disappointing to say the least :mad:

Yesterday I bought some H2O2 and have been using cotton tips to rub it into parts of my Fortress Maximus, especially the right upper leg section. I'm not sure if I'm seeing whitening or if it's my imagination. :p I can't be bothered disassembling the toy to soak the pieces in an H2O2 bath... but one thing I'm not doing is letting it set in sunlight (but one fear is that, because I'm not coating the entire toy in one go, it might yellow the uncoated parts even more).

So, short of doing the H2O2 bath thing (ceeeebs), should I:
* Put the toy in direct sunlight anyway
* Avoid sunlight, but just keep applying more H2O2
* Or maybe expose the toy to "mild UV", i.e. open the blinds in my TF room (the window faces east, so the western sunlight would be bouncing off opposite buildings and back into the window - so it would be indirect sunlight coming in)?

I guess what I want to know is... is applying H2O2 onto the toy still useful for whitening if it's not being exposed to sunlight (but perhaps less effectual), or is it a complete act of futility? I've only been rubbing the H2O2 in the right upper leg, none of the left. I'll take a photo this evening and post it to see if anyone else can notice any difference between the two sides. I've done about 5 applications so far since yesterday afternoon.

Be very careful, Fort Max reacts badly to liquid H202. You will see it go 'lighter' almost right away but it will then begin to break down into a white powdery like surface. All 1987 toys seem to suffer from this. The larger the surface area you 'clear up' the worse it will get.

Here is my experience with it:

Yeah... admittedly I just don't have the patience/inclination (and probably lack of skill) to disassemble Fort Max like you guys did. I recently went to liegeprime's place and he showed me how he'd managed to de-yellow some toys by applying H2O2 with cotton tips. I certainly haven't noticed any immediate results... if there have been any results it's been slow coming. I'm just testing it on one part atm, the right upper leg, see how that goes.

So I started yesterday evening and then applied some more this evening, and here's what it looks like so far...

cheers, will do :)

[liegeprime]

As I told you... apply it and wait for a few days for the effect, mine took like a week. What I did was after 2 days (the applied creme wouldve become semi dry by then) I would wipe off the first applied creme with a wet rag then re apply some more creme then wait 2 more days and do the same. Dont just keep adding creme coz it's be like applying more creme on the creme not on the plastic itself.

[5FDP]

Would it be possible to use teeth whitening paste? It seem to use the same active ingredients. Just curious as I would probably be more comfortable with this than giving a vintage toy a H2O2 bath.

[liegeprime]

It prolly would since it is using H2O2 as well but no one has tested it.. Does it contain nothing else though? Coz there might be other ingredients mixed I that might corrode the plastic.

[Megatrons Cannon]

I have bathed so many Jetfires in H2O2, gotta love that stuff.

[Eruntalon]

I thought that I would bring it to everyone's attention that the Fortress Maximus parts that I kept which I used Hydrogen Peroxide on (I sold the bulk of the toy on ebay) have had some of the yellow return after 2 years of being in storage.

I'll quote myself in this thread:

http://www.otca.com.au/boards/showthread.php?p=330943#post330943


Hi, I just wonder after so many months of your whitening work n FM. Does the yellowing come back?

I ask so as after I have whitening my Grand Maximus, the yellowing returns after 1 to 2 months..it is very sad..

Sorry for the belated reply to your question.

Yes, some of the yellow has returned in part. After two years in storage the whitening process is only a temporary solution. Although the yellowing is not like it was before, I would say as a rough estimate that the fort max parts I still have (I ended up selling the one in the photos except for a few parts) about 25 percent of the yellow has returned. And this is after storage in a dark cupboard!

[kup]

The same thing happened to my G1 Vroom. After the H2O2 it came out a minty white. I put it in a place where it was in complete darkness, away from light, humidity, heat and humanity but it still re-yellowed!

It seems that it is just the 'nature' of the plastic to yellow. You can only 'reset it' with the H2O2 but that won't prevent the yellow from coming back.

[theshape]

Used h2o2 paste for the first time on the weekend for my slightly yellowed great shot. Quite impressed . Virtually all the yellowing gone after 2 days. Will wait and see how long it lasts

Is there a negative of that though? The H2O2 fully reverses the yellowing to a mint state, the problem is that the plastic by it's 'nature' is prone to yellowing unless it is kept in a perfect environment for it.

I'm sure they won't bother. Too much an effort unless they're after a high profit which there isn't for the figures involved anyways.

Yeah even in darkness the figures do tend to revert, same thing happened to my Actionmaster Megatron, the cream seem to not work as effectively now on it when I tried . I gave it a good soak bath before under 1week sun in a bottle which restored it but after 2 yrs or so, signs of yellowing reared up and used the cream for 4 days coating, it didn't seem to whiten as like with the way it did before.

It gives a good explanation of why plastics yellow the way they do. Granted it's in relation to Nintendos but the principle is the same.

Anyway one of the things it mentions is that their is apparently a UV protecting clear coat you can get that could possibly assist in preventing toys yellowing. Has anyone tried it? I found a link to an Australian site selling it. Krylon UV Resistant Clear (http://www.artscene.com.au/shopping/sprays/finishes-and-varnishes/krylon-uv-resistant-clear-spray).

The peroxide reverses the yellowing but does not 'cure it' so that it never happens again. It is still the same plastic prone to yellowing as it always was so it was bound to return.

May take weeks, months or years but it will return. Nature of the plastic used.

[liegeprime]

yeah , unfortunately the plastic used are the ones prone to it... I think same as the plastics used for old computer bodies/cases (which yellows like heck too). Good thing the formula I think has been changed since then.

All plastic of that kind yellows regardless of color. It's just that some of the base color makes it more noticeable than others. For example, yellowing blue tends to look kind of green and so forth.

Huh?? Napisan?? Proof or how to use please??

[CBratron]

The active ingredient of those "oxy-action' cleaners is Sodium Percarbonate. Content levels vary among the various brands and some of them add perfumes, surfectants and anti-clumping agents.

It breaks down into Hydrogen Peroxide (which is what you're after) and Sodium Carbonate (a common water softener). I haven't heard much about it's use for whitening plastics but it's usually the go to cleaner for homebrewers.

[MV75]

Yea, pretty easy. Just add warm to hot water, not boiling, more to the warm side, a bunch of the product and the stuff you want to treat in a container and leave for a while. :)

If you want to, you don't need to. Results won't be as good at first as just using peroxide due to lower concentrations, but it's a lot easier to do, and you can pick up the product in any store that sells washing detergents. Just look at the active ingredient amounts on each package. Last time I bought some was just coles homebrand stuff.

Ironhide does have painted decoes and there was some discolouration on them.
(I also have Car Robot Ox, so RiD Ironhide is a more expendable figure that I used as a guinea pig)

I have bought H2O2 cream to try to use on figures to only apply the H2O2 to select parts, but then the weather in Sydney got gloomy so there haven't been any days with long enough sunlight for me to test it on. Might have to wait till next summer. :) Any advice on what to do for parts that I don't want brightened but also want to protect from sun damage? Would regular sun block work to protect those parts?

a day in the sun shouldn't have a lasting effect on any plastics really. but if you're really worries, perhaps masking those parts is the way to go.

also, I'm not sure if you need direct sunlight for the h2o2 to work, UV happily passes through clouds.

Just fixed my 1/55 Skull 1 Valkyrie thanks to this. It did dull the paint a little but overall I'm happy with the results. Mind you I did use 12% volume as I could not find a large amount of 6%.

[reillyd]

Just discovered this thread, and excited at the prospect of whitening G1 toys.
But its a little hard to follow - one link said UV exposure was the cause, so wouldn't putting your hydrogen peroxide bath in the sun discolour the parts that aren't yellowed?

Will it still work in peroxide bath in the absence of sunlight? If you left it longer or more concentrated?

[UltraMarginal]

as far as I understand (I've never done it myself) putting the Peroxide bath in the sun will activate the solution making the process much faster.

I do believe there is a caveat with this in that if you expose your plastic to the active peroxide for too long you will (I think) damage the surface of the plastic.

yellowing by exposure to sunlight is something that happens over months/years, a couple hours exposure will have no noticeable effect on the parts.

I believe you can leave the bath in the dark but the process will then take days

[CHILENO20]

If you're in no rush to de-yellow your item than it doesn't need to be in direct sunlight to work. Just de-yellowed my VF-1S and currently doing my VF-1A, all the while it never was in direct sunlight. Patience goes a long way.

How many uses can you get out of one lot peroxide

Used mine 3 times so far and no problems. One thing though, if your item has heavy yellowing, these will form clumps that will gather at the bottom of your jug/jar. I had to filter the peroxide before I could use it again.

Question: will hydrogen peroxide clean up sun damage on blue plastic? Got a generations Blurr that needs fixing.

I did the sun-damaged light blue pieces on a vintage Scourge and they came up better, but not perfect. I’ve had better results with white plastic. But there was definitely an improvement.

Tried my hand at bleaching plastic for the first time today. A Masterpiece Ratchet of all things too.
Grabbed a junker online for $30 (I kid you not) and bleached the parts I needed from that so I can still go back to the parts of my original one if I need to.
For the moment I'm only worried about the area around the neck and the left foot (oddly, the left foot on both my one and the junker had some yellowing).
Left the bits in hydrogen peroxide for a few hours today and they had whitened to a satisfactory level. I'm happy with it now.

Can anyone offer an update on some of the things that they used this method on a few years ago? I’m curious to know if the results are still as evident or if some of the yellowing has returned? I read some time ago that plastics whitened in H2O2 are prone to yellowing again quite quickly.

I got a super cheap animated megatron but it’s yellowed

Should i remove the electronics? Will it effect them in any way?

Yes. Definitely take them out.

So i finally caved and ordered peroxide from amazon rather than wait for chemist warehouse to get stock
Turns out it’s creme, should’ve read my screen but oh well

I’m assuming it will still work?

Well i tested it on a test piece and it works
