I'd add a little oxy clean for disinfectant purposes to the water...

Just throw them in the garbage! I have over 60 of DWS stuffed animals and dolls and they are filled with excelsior. My stupid MIL put then through the washer and they weigh 40 pounds each. They are full of mold and have been in a cedar chest to the last 40 years. When I open that chest I can't stop coughing. Who wants that mold in their homes?!

If she made them, can't she just keep the china heads and remake the bodies?

I would separate the head from the body, wash the body with bleach and soapy water, then let dry in the sun for a very long time until they are 100% dry. Etienne is right about the mold, but I wouldn't just toss them out right away, they sound like they are definitely worth trying to save.

Michele has the best idea, cut the heads off and make new bodies. Lots of work, but a grand result!

I'd second or third that. There's no telling what bacteria and solvents are in flood water. It's very dangerous.
