No matter how hard you try and keep that humidity up, sooner or
later you'll end up with a stuck shed. There's just no way around
it. Fortunately, a stuck shed is no match for a little bit of
soaking ....
Start by getting yourself a sealed Rubbermaid container that
your snake can comfortably fit inside. It doesn't have to be
spacious, or have air holes because you're snake isn't going to be
in there for that long.
Fill the container with tepid (luke warm) water until the depth is
no more than 1/2 or 3/4 up your snakes back. Your snake shouldn't
have to "swim" inside the container. It should be able to rest
comfortably on the bottom and still be mostly submerged in the
water.
Seal the container (using the lid) and place the entire thing inside of your snakes
enclosure for about 1 hour. Placing the container in your snakes
warm enclosure will keep your snake at the correct temperature and
it will also create a mini "sauna" effect inside of the container to
help loosen the stuck shed.After about an hour, remove the snake
from the container and let it crawl through your hands while you try
and slide of the stuck shed. If your snake is relaxed, you may be
able to restrain it temporarily while you work off any skin that's
left, but the majority of it should basically slide off in your
hands.
If after working with your snake for a brief amount of time there is
still some stuck shed, you can put your snake back in it's enclosure
and repeat the process in a day or two in order to minimize your
snakes stress. Keep repeating the soaking process each night or
every other night until all of the shed is removed.
