I have finally made my decision:
I will wash my Dolls' faces!
Actually, I already have! :)
Here are some pictures of my Agnetha doll before and after I washed her face.
At first, there was just a little bit of dirt at the side of Agnetha's face.
There was a water stain below her mouth and the stain on her right cheek (viewers left) was getting bigger.
She had also gotten another stain on her other cheek.
All three stains have gotten a bit worse.
The stains were getting worse!
We finally cleaned off the stains with a cotton ball, soap, and water. The stains disappeared and now, Agnetha looks as good as new!
