Soak it in warm water for a minute, until it is completely soft and springy. Never use it dry — that is how people end up irritated. Squeeze out the excess, then work in light circular motions over damp skin, with your cleanser or with water alone.

Afterward, rinse it thoroughly and press the water out between your palms. Do not wring or twist it — that tears the fiber. Hang it somewhere it can dry fully between uses.

Replace it every four to six weeks. They are inexpensive for exactly that reason. If it starts to feel slick or hold an odor, it is past due.
