Also on a flood theme, for those cleaning up from the floods, here is a nice_article about how chlorine bleach is not effective against mold, and what alternative is better. They suggest a mix of borax and vinegar, and while that seems likely to kill about anything I'd be careful handling that too.

Flood Clean-up Stay away from bleach Our first instinct is to bring out the chlorine to disinfect and kill mold. But a study conducted by Professor Jeffrey Morrell, Dept. of Wood Science, Oregon State University found that bleach "doesn't eliminate the surface micro flora." It doesn't kill the roots of the mold, only bleaches it so we think it's been cleaned away when it hasn't. So not only is it ineffective, its fumes are harmful to both humans and the environment. Try This Instead Mix: 2 ounces of borax and 1 cup of white vinegar Spray on the mold, let sit for up to 60 minutes and then wipe the area. The mixture will prevent mold from growing back. -- from After the Flood, Green Living Online http://www.greenlivingonline.com
