However I'd say this is completely unnecessary, SOOW is water resistant afterall...
The water resistant designation in SOOW applies to the outer jacket. If the ends are submerged, water can wick up into the cord via the filler and seperation paper. The proper thing to do would be to scrap them, and replace with new. Second to that, locate an electrician with a 'Megger' and have him test the cords.
Do not use any solvent type cleaner (such as CRC contact cleaner) on the connectors without first verifying with the connector manufacturer that the plastic the connectors are made out of is compatible with the solvent. If there is any doubt about the connectors, just replace them. Were talking about $50 worth of connectors here, its not like you had a few dozen pieces of socapex underwater....
I don't think there's a need to replace the connectors so long as they aren't already corroded.
Let them sit for a while, slice a little off of the ends to check if the paper between the conductors is wet. Even if it is, I don't know that it creates a problem unless the conductors have punctures in their insulation. Just the paper being wet won't cause anything to short out. It might give you problems with the flexibility of the cables and how long they'll last, but there shouldn't be any conductivity problems.
Scrapping them is way overkill, 600ft of SOOW aint cheap, especially for a school program. If your really nervous about water wicking up in there, take your handy multimeter, set it to continuity, and then do a continuity check on each pin to every pin. If they only respond to the pin your contacting, your in the clear (I really doubt that this is an issue at all, but if your super concerned, go for it). The cleaner mentioned is safe, it says so on the website and a 5 second googling got me that information: CRC Industries Product Detail . Realistically, the chance of it having issues after being thoroughly dried out is slim to none, unless it was submurged for weeks or something.
And if that stuff is at all new it has nylon instead of paper in there. Along with plastic jackets over each wire inside the rubber insulation inside yet more rubber insulation... yeah, i doubt there is an issue.
The insulation on the wires is still rubber and/or plastic, both of which are waterproof...No. Several manufacturers still use paper both in the filler and as a seperation layer between the jacket and conductors.
