Best ways to get blood out of clothes

Hydrogen peroxide works every time! Squirt hydrogen peroxide directly from the bottle onto the blood stain. It will bubble up and lift the blood out of the fabric fibers. Rinse with cold water and continue saturating in hydrogen peroxide then rinsing until the stain is gone. Wash your item in the washing machine immediately afterward (hydrogen peroxide could potentially bleach the fabric if you let it sit without rinsing/washing).

Don't use warm or hot water when cleaning blood out of clothes!! The heat causes the proteins in the blood to coagulate and set into the fabric, making it much harder to remove the stain. Always use cold water when cleaning blood out of clothes.

I like to dab the blood with cold water to stop the stain from running or setting. And then I'll treat it with some hand soap or laundry detergent. Rub it in gently with your fingers or rub the cloth against itself. Then you can hand wash it out (with clean water!) or throw it in the laundry and it should come out.
