You can put your snake in a damp pillowcase for a couple of hours. As it moves around, the shed usually comes off against the pillowcase.
I had a terrible time getting mine to shed properly at first. I keep them on sand, and they have a favorite hide, so when I notice one is in the blue I simply pour water onto the sand under the hide. Works everytime!
