I've removed a lot of face ups in my short time in the hobby (I've been around for about 4 years). I've used nail polish remover, Winsor and Newton (referred to for the rest of the post as W&N), and various strengths of rubbing alcohol to remove face ups.
I have a few dolls I've been meaning to redo, and I thought while I was at it I might as well take some pictures and do a few comparison/tutorial posts. The next post will be my face up tutorial. I may film it, but I haven't decided yet.
I've decided to do a comparison/how-to feature for these so you can decide which is best for you.
I'm not getting into the acetone/no-acetone debate thing though. I don't know enough about acetone to say either way. I've heard horror stores, but then I've used products with acetone and had no issues myself. So, it's best for me just to avoid that subject for now.
