My mom was told by the man that owned a dry cleaners to use salt water for a soak. It was to remeove a lot of dried blood from a jacket. I'm not sure if it worked, just remember that is what he told her. I have a quilt that my mother worked on with me, and she got a drop of blood on it. She made a joke saying she gave her bloodf so that I had something to always remember her by. tHAt small blood stain stayed on the quilt!
