How long does it usually take to fade say pen/marker marks in hydrogen peroxide in the sun?I don't know about glue stains, but I think regular sun fading works better for pen and marker stains. The less direct the sun is in your location, the longer it takes. Some people report it taking months in cloudy areas. The sun is very intense where I'm at and I can do it in a day or two, but many places are not that lucky. Hydrogen peroxide breaks down into water and oxygen quickly when exposed to light, so if you're in a cloudy area and need to use it for an extended time, you may need to dump it out and replace it periodically. I don't think we know enough about this method yet to know if prolonged exposure puts the pony at a higher risk for bad side effects. If everyone keeps posting your results, I really want to learn more about what other folks are observing.Yeah, I actually tried getting the glue stains out by just sunfading her all last summer and no difference so thought I'd try the peroxide soak. Might end up baiting her if I can't get the stains out What about painting over the glue stains?

My only concern about stuff being so promoted is the people who now view it as basic cleaning, thus nothing to keep track of or disclose during sale. This is a RESTORATION so a pony is no longer original, and will never be mint even if it looks that way. the pony should somehow have an identifier as a reminder for what was done to it- to preserve the value of ones collection. (I use some white thread at the base of the tail to mark it as treated by H202). I mostly stopped buying ponies from collectors/pony resellers years ago due to getting bit with undisclosed restores sold as Mint or NM.

I mostly stopped buying ponies from collectors/pony resellers years ago due to getting bit with undisclosed restores sold as Mint or NM.This is a huge concern for me. I would never wish to buy a pony that has been boiled, treated with HPO, bleached or sunfaded for long periods but I think that with more people trying out restoration techniques these things will become increasingly common. I have most of my collection now but there is still a risk that I will buy those remaining expensive ponies only to haver their hair disintegrate or the brown spots come up after a few months or they will go hard. There is no accountability because these interventions just speed up decay that would have happened anyway, the question is how fast and how long do you have left to enjoy your object? I feel bad for new G1 collectors because it is getting rarer to find ponies that have not been damaged by collectors. I have a background in scientific research and have experience of collections work in museums so I feel as though I am a relatively safe pair of hands, but when I see the damage some people do to ponies it's difficult not to begrudge people just 'having a go' with household chemicals and no understanding of how they interact with plastics. Generally I've tried to avoid threads where I think people are getting things wrong especially if the correct information is out there and has been repeated time and time again. I think that people ignore my posts (because why should I be any authority) and it makes me unpopular, but sometimes I do pop something in because I think it's a shame that ponies are being damaged. In general, harsh chemicals and treatments are not a valid 'quick fix', they only speed up the decay of the objects in the long term. Patience and elbow grease can do a lot without damaging the pony. I did post a load of repeated info but I really need to stop myself.
I began with dissection and found that the spots (which I am starting to call colonies because I am increasingly convinced they are bacterial colonies from their growth patterns and what happens to them when they are boiled)
All RIGHT! Now we're talking, thanks for the hard data!Some questions: 1. On the material compatibility chart: which material on the left is a pony anyway? All those material types are way over my head...also the consumer HPO we have available is 3% which is 1/3 the lowest concentration, so do we scan across the concentrations columns to extrapolate where 3% is? It's probably not linear right?
...*iron tail washer: No, I get rid of that thing right away, iron=bad, bad, I like nylon, nylon goood plus don't put tail in the peroxide cuz I did notice it hurts the hair color at least for sure. I got some stainless washers for tail but they aren't stainless, are plated over iron so if desperate was thinking of maybe drilling holes in dimes for new washer when nylon not available or good nickel-based real stainless not available...
It's PVC, polyvinyl chlorideThe lowest concentration on the chart is 10% with exposure for 48 hours. My understanding is that collectors are using lower concentrations but with longer exposure times.
You might find this interesting too: http://www.sciencedirect.com/science/article/pii/S1658365514000880Anyone know much about any of these things? "In order to protect against the damaging effects of UVR on polymers, addition of UV light absorbers, excited state quenchers, hindered amine light stabilizers (HALS), hydroperoxide decomposers, radical scavengers, pigments, fillers and antioxidants are an effective and convenient solution in practice."
I imagine a sun faded pony would be okay for a child to play with- would an oxy boil pony or peroxide-soaked pony be okay as well? I have a few ponies with unacceptable stains and I would like to try to get them out but I need them to be child-safe afterward. Some of the pen stains, I have tried the method of heating the pony in hot water, applying antibacterial soap, and scraping. I have had little success in drastically lightening the pen stains but this takes a very long time and I am not sure if it is worth it for the purpose. Any thoughts?

Ok, personally I have stopped giving children vintage toys period I keep my stuff out of reach of both children and pets.(even those in seemingly good repair). I posted something a while back about a lab taking 80's stuff and finding lead and cadmium in the vinyl (yes, even in 80's MLP). it can be absorbed through skin. So now I hoard extra pretty g3's and g4's for my kids that get to "see the collection and get a free pony from the pony lady" box. I would never give a child any vintage toy which was once, or becomes slimy to the touch or heavily weathered. (and sunfading, heat UV this all starts damage/breakdown) Sadly since lead and cadmuim ended up in our playthings anyway and the concern is as they break down they can be adsorbed through skin. you also don't want them getting old plasticizers all over their hands either. If you have concerns though the person to ask is your pediatrician, or a musuem conservator with knowledge of 80's plastic's.Exceptions of course are older kids who want them as a collectible and not for play. They can't hurt you in a curio.
