I don’t know whether anyone of you knows the problem but I assume you do. I bought Collector Barbie dolls for many years and for some reason I don’t know some of them developed green ears. I have to say I don’t like green ears at all. I know it has been a problem for decades. I the first owner of some of the Collector Barbie and I stored them all the same way. This is what I did when I saw green ears. At first I removed the earrings from the doll. Most of them had no hooks at the end in the head. So it was easy to remove them. Then I cleaned them with a cloth for costume jewelry. After that I put them in a tiny plastic bag to be sure that the earrings don’t stain the clothes. I put one of these little silicone bags inside the box before I put the box with the doll in my shelf. Then I forgot about the issue. When I looked into the box again….surprise the green was gone. This is so strange. I really did nothing and now it’s gone. I realized the green in an early stage.
Maybe this makes a difference!? I hope my post can help anyone.
