My community suffered two horrible floods. The first was in 1969 and the second was in 2011. After the 1969 flood, we were told to wash things with bleach water. We saved many things and had no problems with mold. In fact in my basement, we pulled the paneling away from the studs, cut out the insulation about 4 feet up from the floor and washed everything with bleach water. After things dried, we nailed the panel back in place. No problem for 42 years. During the clean up for the 2011 flood, we were told to throw anything that had been touched by flood water. I hired a clean up company to do the work. Cleaning up after a flood was a lot easier at 19 than at 61. I watched them throw stuff that I just knew could be cleaned up. I started washing things that I knew could be saved. No problems after 6 years. Both floods had sewage mixed in the water. In the '69 flood, water was up to the rafters between the basement and main floor. In the '11 flood, the water was about 4 1/2 feet deep in the basement. Yes, quilts and anything that can be washed can be cleaned up after a flood. Didn't know about using borax.
