Had the same problem. I also had a boat and the battery box in a boat is usually stored where rain will not fall on top of it. Just drill a couple of holes and the water will drain out.

Tilex Mold and Mildew. Sounds crazy but works great. Spray it on, roll it up. Let sit for five or ten minutes and then open the awning. Spray with clean water and let dry. May need to wipe down some stubborn areas but it works great.
