What is the best way to...

[YamahaFreak]

...completely and safely dry out a CRT TV mainboard that has become soaking wet, through washing, rain inundation, flooding, or otherwise? I have two boards that will need thorough drying and I am worried most about the flybacks shorting. I seem to recall being told to put them in the oven at the lowest setting (150 degrees?) but I don't remember for how long...or if I should even try it. What do you guys do when a board needs a serious cleaning and drying, when the leaf blower and toothbrush just won't do?
