I'd probably just leave it till next time. Seems like if you wait too long after they shed it doesn't want to come off as well.
What you can do next time if you notice a bit of stuck...is get a snake bag or pillowcase (the lower thread count the better) and get it wet with warmish water (lukewarm). Then wring it out so it doesn't drip. Put your snake in the bag and tie it closed then set the bag on the warm side of their enclosure. Leave for about an hour. Usually the moisture and warmth combined with the snake moving around inside the bag will work off a lot of stuck shed.
