After cleaning the green inside and out with alcohol and a swab I pull off a small section of cotton ball and saturate it in CLR. I squeeze out the excess and set the cotton ball over the green. I change the cotton when it has dried and reapply CLR. If the green is oozing or looks like the earring hole may be full of green I will soak a piece of thread in CLR. Using a needle with a small eye, I use the eye to push the thread into the hole, just far enough to get the thread inside and then I pull the needle out, leaving the thread in the hole. I leave it in there a day or two and refress as needed. You need to be careful so you will not rip the earring hole so it is a good idea to warm the head up first if you are worried. Sorry, I did not photograph the thread method when I took these pics a couple years ago.
Here is my PT with seeping, oozing green. I used the cotton and thread soaked CLR on her. I also used just the cotton on this Swirl because she just had shadows of green around her ears. After you are satisfied with the results, wash the head to get the CLR off.
Here is the PT relaxing with the CLR treatment.
After a day or two the green is dimishing.
Ater no more than 2 weeks for the Swirl and just a couple days for the PT, here is the final result.
