Help!

My return hose popped off the false wall on my Aquapod 12G. It spilled water all over all my switches and electrical equipment. I'm not worried about the cheap power strips, but I am concerned about some the more pricey electronic stuff. The GFI outlet popped instantly.

What do I use to clean it? I opened everything up with a screwdriver (split every housing) and aimed a fan at them. It has all dried with a salty stickiness. What can I clean this stuff with? I was thinking non-lubricated switch cleaner from radio-shack.
