How do I remove mold from my deck?

I have a composite deck, similar to Trex. I tried using my power washer to remove mold/mildew that presented after a very rainy several months here in PA. The deck faces south and does get full sun for a significant amount of time. Power washing with water either lifts the fibers of the material, or doesn’t clean away the mold. Help!?!
