I had a similar "Accident" a few months ago ( http://www.rv.net/forum/index.cfm/fuseaction/thread/tid/30103318/gotomsg/30119506.cfm#30119506 ) Four months later, it seems as though efforts to clean up at the time were successful. I moved everything out, mopped & dried everything accessable, desmantled and dried eveything else, opened every door and window, kicked on the roof fans, and placed fans everywhere possible along the floor. All while having to listen to the other half.
Today; No Mold, No Smell, No Soft Spots in the walls or floors. I got lucky!
Lesson learned: when flushing the BWT, STAY WITH IT! I let myself get distracted with preparations for moving...BAD IDEA!
