Well, he already turned it on, so... But anyways, I find the water to be of little consequence for PCBs. It's the stuff IN the water that does them in. Even after they're bone dry, the minerals, electrolytes, etc. that were in the water remain dried onto the PCB, and can still conduct electricity.
A common thing that I do with small PCBs that've been contaminated is to simply wash them off with soap and water, and a soft bristle brush, then let them dry. Sounds all kinds of wrong, but I've had good results.
