Hi all you wonderful pony people! I'm pulling all my old childhood play sets out from storage. They need some cleaning up, stickers need putting back on etc. But I noticed a lot of yellowing issues on my dream castle. I'm so sad! That was my favorite set as a child, and its so icky now! I'm going to try to re-brighten the pink back to normal, and re-whiten the floors. But i cant exactly dump the castle in a jar of hydrogen peroxide. Has anyone tried using the "retrobright" recipe to restore their play sets? Or is there another, safe method. I have a precious two year old and an inquisitive Old English Sheepdog at home. So the safer the method, the better! Plus I realized I need to buy a lot of the corresponding accessories. I hadn't realized how many of them have been lost over the years. (On the plus side, I have almost everything from my perm shop!) Sigh. Thanks for all your help!
