There is yet another 4 step method for removing bloodstains.

1. Wet the stain with cold water
2. Coat the blood stain with powdered meat tenderizer and more cold water
3. Rub in this paste you have formed and let the shirt sit for one half hour
4. While you're waiting use this time to make sure your alibi is solid then rinse

Just another helpful hint from your weird uncle Frank.
