How do you clean a face sponge?

I have one of those sponges that you use to work in the cleanser (face) and it looks like it is getting dirty, how do I clean it? Should I just soak it in soapy water or is there another remedy? It is meant to be reusable by the way.
6-9 inches of nappaliscious hair
