One of the reasons I no longer actively collect figures is because of yellowing, the other is space, I already have too many,

AFAIK it's ABS that yellows over time. You can use the peroxide treatment, but it can become streaky if you do it wrong. it's also finicky because of paint, since paint and peroxide don't like to mix. I think I've seen treatments with using JUST UV light, but I can't remember if they poured peroxide into the bin first. If you want to use cream, though, use hair bleach and mask off all of the painted parts, and move the cream around so that it won't streak. Leave it in the sun or in UV light so that the reaction will work. The yellowing may come back over time, but hey, it's nice to have a decent looking model for a while, right? (A good place to research this is in the retro PC/Console community)

Hi lovely people~ I am considering of buying misb YF-29B (the greyish navy blue version).

Anyone knows how it stands through the 'yellowing' after so many years of release? Also, is the discoloration 'even'? Because they often use different plastic for different parts of the plane and sometimes the different degree of discoloration really bothers me. 😬

Far as I've read or seen it's only the white parts you'd have to worry about.  Assuming you're not leaving it in direct sunlight all the time.

Make sure you see plenty of pics of it , if you can. It should be ok. But no guarantees. I would assume the seller would be honest about it , if it had any yellowing.

Might not be the best thread to post this but today I took out my Arcadia VF-1S Hikaru out of storage and noticed that it had turned brown where the pieces were cut from the runners and where two pieces join (i.e. the two leg halves) but not on other surfaces of the toy.

I‘m curious what that is (is it actually yellowing?) and now I’m anxious to pull my Renewals out of storage.

Por lo que he leído o visto, son solo las partes blancas de las que tendrías que preocuparte. Suponiendo que no lo dejes expuesto a la luz solar directa todo el tiempo.

That's not true at all😔

Did the previous owner display it on direct sunlight or something?

From what I been told he just left it on the box storage and taken out to clean and it turn to yellow. If the plastic expose to direct sun light might already discoloring the orange part as well it will already break the plastic to piece . However on this case orange plastic still quite pristine on the plane.

Ok... all plastic eventually yellows due to the laws of science. There's no fighting it. Best option is to buy dark grey or black valks to limit the visibility.

I however have some toys and diecast figures over 20 years of age, and have zero yellowing... while, my 1 year old Lego sets with white blocks just for display, yellowed, and are not in direct sun and in a smoke free place.

I also have a Spawn 10th Anniversary from 2001 sealed in the closet, and the blister packaging is beyond yellowing... it's now a dark tinted coffee brown. While the blisters of other brands are still crystal clear pristine...

So conclusively, it also comes down to how cheap the material is...

What UV light do you use? I have a Usb LED black light but im not sure if thats good enough. I usually use sunlight, but my apartment doesnt get direct sunlight

 

A little warning tho dont leave the hair cream too long on Yamato tampo, i found out the hard way it melted/destroyed them.

so far I mostly use the sun light. I find UV light kinda slow and take longer time to restore the white. So far my hair cream has no issue on bandai VF decal. in fact it restore the decal from yellowish to white back.

Has anybody had a good experience where the plastic doesn't re-yellow after whitening? I've only tried on my Beagle Mospeadas and they looked fantastic when I whitened them but then after being in a closet for a year they were more yellow than before.

I'm wondering if there's a difference if you do it without the UV light involved. I understand just hydrogen peroxide with heat will work to whiten as well but haven't tried.
I have a few valks that I'm heartbroken about yellowing and would really love to get them back to beautiful.

In my case the toys were originally yellowed from sunlight, so my hope would be that if kept out of the sunlight they would remain white.

So far I haven't yet encounter any restoration VF of mine turn yellow yet however white plastic will eventually turn yellow again after awhile no matter how much you treat it. The only way you prevent that is by paint it which last forever.

@chriswoo i vaguely remember that you're using this haircream on another post. Which one is it? did we just need to smear it over the yellowing parts?

I am using 6% only which is safe for decal and painted surface.  however more resilient yellowing can use 9% or 12% however do it at ur own risk as it migh destroy the decal or corrode any metal contact it faster
