Basic rinse-out, housewash the walls and hose the rest out. 9000 sq/ft and 3 hours, not bad!
A couple notes, glad I had the 12v sump pump because the only drain was outside the door. Had a helper using a floor squeegee, lots of low spots. A 6’ water dam would have been helpful.
Also whatever was in the air was burning our eyes some. We had to do a couple eyewashes, it was either the bleach or whatever got kicked up off the floor. There was zero ventilation in there.
