A couple of things to keep in mind.
Pick through and remove fiber that has more than just a little vegetable matter. You can set it aside and try to work with it later, but you don't want it to migrate into all of the fiber.
Don't do anything that will felt the fiber, no stirring, dumping, pouring water over or agitating the fiber. Don't shock it with abrupt temperature changes.
