Blood stains are one of the most difficult stains to remove, especially once it is dried. Blood is made of protein and is best cleaned with an enzyme cleaner. If no enzyme cleaner is available, there are other ways to remove a blood stain. It is best to catch a stain when it is fresh and can be rinsed away, but it is also possible to remove a set in blood stain. Removing a stain from white clothing is easier than removing from colored clothing.
Hydrogen Peroxide Method
Place the item over a sink or container that will catch the liquid when it runs through the fabric.
Pour hydrogen peroxide over the stain. Let it sit until it stops foaming completely.
Check the stain. If it is still evident, repeat the hydrogen peroxide.
Rinse the item in cool water and wash as usual once the stain is gone.
Glass Cleaner Method
Spray the stain with standard window cleaner. Allow it to soak in for a few minutes.
Use a brush or washcloth to scrub the stain lightly.
Wash it in cold water with your usual detergent. Check the stain after washing and repeat the treatment if the stain is not gone.
