I would start off with cold water and work from the outside in, lots of it with rubbing with a finger nail. If that is not successful sprinkle it with salt and leave for an hour or so and then continue with cold water washes. Whatever you do don't use hot water as that will 'cook' the proteins in the blood and set the staining. (All advice from my Mum should I have monthly 'accidents', which has worked for me).

Hydrogen peroxide has worked for me every time. Learned to use it from the doctor's office I go to. The nurses said that is their recommendation when folks that had blood drawn would get a drop or two of blood on their clothing. I've used it when I'd accidentally prick myself doing applique or hand quilting.

The best thing to get blood out of cotton fabric is saliva. The saliva of the person who got the blood on the quilt.

I've not tried any of the options you mentioned. But good luck!

A dear older lady unknowingly got blood on my quilt. She had a spot on her hand that was bleeding and she was not aware of it. I discovered it about an hour after she had left my house. The spot is on a light blue block. I have read about using salt water, white vinegar, oxyclean, zout and several other suggestions. Does anyone have any experience or suggestions? The spot is about the size of a quarter.
