This is similar to what I've done, with great results, except that I soaked the pillow case, wrung it out, closed the end and then just put the snake in it and the whole package back into her tub rather than spraying her down. With enough room to reach warmth and cool, I left her in there for about an hour - dark, quiet, not floating in water, with friction and humidity. When I took her out, there was no stuck shed left. Then I got to try and get all the pieces of shed skin out of the inside of the pillow case... but the snake wasn't stressed in the least.
