There's a product I've used for my guy when shedding was stressing him out. He would always sit in his water dish looking blue, so I tried "Shed-Ease" by Zilla. It's a reptile bath that comes in an 8oz bottle with a measuring cup. You add a little bit to a warm (sink in my case) container of water and gently soak your snake in it for a few minutes. It worked for us, his skin came off in one piece.
