My first area of attack would be to remove any and all moisture from your camera. Any hardware devise can be drained of moisture by placing it in a container with "UNCOOKED" rice. The rice will draw all moisture out after 1-2 days. I can confirm this works after my phone went swimming once. The I.T. guys at work recommended this procedure for any hardware that gets wet. Give it a go, what have you got to lose.
