So, I'm guessing she has retained part of the skin? Here's what you can do to get the rest of if off quickly: Get a Gladware or other type of lidded container. Place some crumpled up wet washcloths or paper towels in the container. Then put your snake in there for an hour or so and let her slither around. She will probably work all the retained skin off that way, but if there is anything left, it should be loose enough that you can gently work it off of her with a wet washcloth. It's always worked well for me.
