Sub Floor Water Damage

[Friartuck]

Not exactly a Garage type question, but looking for opinions regarding a 3/4 inch Tonque & Grove subfloor underlayment (8'X20')that was immersed in salt water for about an hour. This is aftermath of hurricane Sandy in NJ. Top side covered in tile. Floor has dried from both sides and not buckling or delaminating. Originally glued and screwed down. This is just a portion (utility room) of the whole house and is a real PIA to have to replace. Rest of house has hardwood southern pine flooring and that seems to be OK, (not buckling). Can this subfloor be saved?? Any remedies or preventive measures to save it? How wet to require replacement?

Put fans under the floor if possible to dry it out. If no further damage, i would wait it out, but keep an eye out for mold. People around here used a clorox/water mix to spray on surfaces to help prevent mold, then dried the surfaces out. I had a house with hardwood floors and a plank subfloor. The hardwood buckled to foot high peaks and had to be removed, but the plank subfloor was able to be dried out. I had a whole house fan, along with ceiling fans in every room that I ran for two weeks straight. Refloored with plywood and carpet later, and all was well.
