You need to wear a face mask of some kind while you're handling this fabric before washing as mouse droppings carry hanta virus, a very bad lung disease. Washing alone is not enough to kill the virus. I don't even know if liquid Lysol and hot water is enough to kill it. You probably need to do some research online to kind out how to be sure you are not infected. Hanta virus is a very serious disease that often causes death. A bunch of free fabric is not worth dying over. I'm not trying to scare you, but just a word to the wise.
