I have found that during the past year, many of my GI Joes, vintage and modern, and vehicles, have yellowed. Where I live now, heat gets quite intense, up to 31ยบ c inside home, and with humidity levels of 90 % for long periods of time. I am now about to buy some sort of AC unit or climatization, but unsure of how or when. I thought before that keeping them in sealed bags, on a big plastic bag, in boxes, out of the sunlight, would keep them ok, but it seems the high humidity has been too much.
What do you do? are your local temperatures and humidity levels good enough, do you have a constant climatizer? do you have some cheap trick, like storing your joes in foil bags and silica gel?

I think there's a variety of factors and there's no 100% set cause of yellowing, but the general causes are sunlight, heat, handling (skin oils), and type of plastic used.
For myself, I do the following: 1) Positioning. I keep my collection out of any direct sunlight in their display areas. Direct UV can do serious damage in short order (like within days). 2) Temperature control. All of my figures stay in the house which is generally between 70-80 F (21-26 C?) year round. Avoid storing stuff in a non-temp controlled area such as a garage/attic/storage shed if at all possible. 3) Cleaning. Any time I add a new vintage item to my collection, I generally disassemble and clean it with dish soap and water (unless it's being restickered and then I use different cleaners). This gets rid of years of any previous grime, dirt, skin oils, etc. 4) Plastic used. There's not much you can do about this. But if you're looking at adding a vintage item to your collection, make sure you're OK with the current level of yellowing. MOC / MIB items can even have yellowed over the years while still sealed in their original packaging. As far as packing/storing in baggies with silica gel, I'm not sure that's any guaranteed prevention. Retro Blasting did a Youtube video on this awhile back where he compares one of his figures with one of his brother's figures and discusses what he believes causes yellowing. Interesting to watch. There are methods to remove/reduce some existing yellowing such as Retro Brite, but so far I've only used it on a couple of vintage Buck Rogers figures with mixed success. Anyway, hope this helps Last edited by Cryoguns; 04-22-2021 at 11:47 AM.. |

All my stuff is kept in a tomb like environment... A completely black room that is climate controlled with a dehumidifier running... Ah the joys of collecting.... sigh

I keep the temperature at 74 F/23 C. The A/C also keeps humidity under control. Keep everything away from sunlight and everything is pretty much in plastic totes for now.

I agree with what was said above. I would add using acid free storage bags if you are storing them. Regular ziplock bags have acid that may degrade the figure plastic over time. Do a search for GT bags. They have a whole assortment you can choose from.

My G.I. Joe 25th Anniversary figures the few that I have i pretty much keep the contained in a plastic shopping bag for the past few years. I really need to get a plastic storage tub for them like I have my Star Wars figures in.
But my 25th Anniversary GI Joe figures are still in great shape anyway so im not worried |

Many thanks for the replies ;) .
My current house varies from 12-31 C, so I guess that is a big no-no. I always clean any item I buy, simply for higienic reasons , as many are grimy. Before I placed them in very hot water, now I tend to just use an alcohol based cleaner, and being careful with logos and the like. What I buy is usually in great shape, and after being with me 1-2 years it's ready for the bin :( . I know for a fact that if a figure has been in direct sunlight for a couple days, sometimes it's doomed; you might not see it yet, but the breakdown at molecular levels has started. But this has never happened to me. Just watched that video of Retroblasting, I don't believe the oil theory, I've had figures that I've literally never touched, and have yellowed all the same. In his particular case, I think just they were on sunlight rather more, as they were more played with, or they were near heaters or near cleaning products, and he must be keeping his joes in a temperature which is rather high, and hence, made yellowing prone to happen. The question about ziplock bags, I think, is that basically they keep the temperature. Hence, if the bagged figure reaches a certain temperature/humidity, instead of cool off/ dry off quickly, that high level stays for longer. Anyway, for the moment I think I will have to spend a few hundred $$$ in plastic boxes, and thermic bags (this just as a slight precaution and reduction), and a few more hundreds in a whole climatization system.

Protech Star Cases. Some of them get a little more sunlight than they should, but a lot of them are recards so I don't sweat it too much. I keep it cool in there, just have to keep my boy from ripping them open lol.

Yellowing can be caused by any of these, or any combination heat/florescent light/UV light/off gasing. The video below, does a pretty good analysis of the of using UV light to cure yellowing.
I also put UV film on the windows of my house where I will have collectibles on display. |
