Yep it does and won't bleach out the fabric If the colors are set. Use it on fresh blood before washing, but it will lighten old stains as well. Don't delute. Let it sit a few minutes, then throw it in with the wash and regular detergent.
There are fabric cleaners and wash enhancements that have Hydrogen peroxide in them and they will bleach out the fabrics. I've done this to denim and no change or spotting was ever noted. It is how we nurses kept our white uniforms white!
