A cut, bruise or unexpected menstrual period can result in blood stains on clothing and other fabric. If the blood has time to dry, it's also had time to soak into the fabric fibers. The task of removing dried blood stains is achievable but must be done with care to ensure the stain isn't spread further. Proper cleaning techniques and supplies help in getting a dried blood stain off of the surface and out of the fabric fibers.
Lay the clothing with dried blood stains on a flat work surface with the blood stains facing up.
Brush the dried blood off the surface of the fabric, using a dry scrub brush. Shake the fabric outside or brush the dried blood residue into the garbage.
Prepare a solution made with enzyme stain remover and cold water in a bucket, according to the directions on the stain remover. Soak the garment in the solution for 10 minutes to loosen the remaining blood stains from within the fabric fibers.
Wash the garment in cold water with oxygen bleach and laundry detergent to remove any last traces of the dried blood stain. Do not place the clothing in the dryer if any blood stain remains. Instead, soak the garment in undiluted white vinegar for 10 minutes before washing again.
From Upholstery Fabric
Brush off dried blood residue, using a dry scrub brush. Move the brush in one direction to force the dried blood to flake off the surface of the upholstery. Vacuum up the dried blood afterward.
Mix 1 tbsp. of dishwasher detergent with 2 cups cold water in a bucket. Soak a sponge in the detergent solution and wring out the excess moisture.
Dab the remaining dried blood stain with the solution, beginning at the outer area of the stain and moving inward. Rinse the sponge as dried blood is lifted, then continue to blot with more detergent solution until the rest of the stain is gone.
Rinse the upholstery by sponging it with a damp cloth. Absorb moisture by pressing dry cloths into the upholstery to remove as much dampness as possible. Allow the upholstery to air dry.
