get a small rubbermaid tub with a locking lid, drill some holes in it, fill it up with warm water just deep enough that it goes halfway up your snake's side and put the snake in it. put the tub on the warm end of the snakes enclosure (so the water doesnt get too cold) and leave the snake in it for about 30 minutes, put the snake back in the enclosure and it will rub off on its own fine but you can help it after you've taken the snake out if you want.
