When you notice your snake clouding up, raise the humidity to 75% until they're done shedding. Substrates that hold moisture help a lot, but only if the ventilation is mostly restricted- IF you're using a glass tank of any kind, you want to cover most of the screen top so the humidity stays in.
Provide a humid hide (keep the sphagnum moss damp during his shed).
Soak- I didn't mean to soak the whole snake- you'll need to soak a towel/cloth/or sponge & keep it on his eye-cap for a while until it softens enough to gently rub off. But a Q-tip is pretty small for this. The "shed-aid" type products don't usually do anything more than plain water- fyi. You could also just wrap him in a damp towel, then put him in a ventilated tub for a while- he'll probably get the shedding done.
