For fresh stains, sources suggest that you should put the fabric under cold or lukewarm running water in your sink or bathtub, letting the force of the water itself dissolve the blood.
If residual blood remains, lather up some soap, and scrub the rest of the stain out with your fingers or a scrub brush. According to cleaning expert Jolie Kerr, "Regular hand or bath soap works really well on blood".
For Older, Dried, or Super Stubborn Stains "Dab a washcloth dipped in hydrogen peroxide directly on the spot, then rinse well with water," says Kerr. Toss it in the washing machine as you normally would. Even if you don't do laundry for a few days, the stain should disappear. (Warning: This works best on whites or light-colored items because hydrogen peroxide can cause colors to fade the way bleach does.)
Spray on an anti-stain all-purpose laundry product, or use a spot cleaner that specifically targets blood.
