Act fast; rinse with cold water from the back of the fabric
Blot (don’t rub) to lift as much blood as possible
Soak in cold water for 30–60 minutes, then re-rinse
For fresh stains: apply a small amount of liquid laundry detergent directly to the stain, gently work in, then wash in cold water
For dried stains: soak longer (up to 2–8 hours) in cold water, then wash
If detergent isn’t enough: soak in an enzyme-based stain remover per label directions, then wash cold
For stubborn stains: use hydrogen peroxide (3%) on the stain, let sit briefly, then blot and rinse, then wash cold
For delicate fabrics (silk/wool/lining): use cold water soak and enzyme cleaner labeled safe for the fabric; avoid hydrogen peroxide unless the label allows
For upholstery/mattresses: blot with cold water, then apply a small amount of enzyme cleaner or detergent solution, blot again, and air-dry thoroughly
After treatment, wash normally in cold water and check the stain before drying
Air-dry until the stain is fully gone; heat can set remaining blood
If the stain remains after washing: repeat the enzyme/detergent treatment and re-wash cold
For white fabrics: oxygen bleach (color-safe) soak can help; follow label directions and rinse well before washing
Avoid hot water, tumble drying, and ironing until the stain is completely removed
