Blood Stain Eraser

Don’t use hot water on a blood stain. It will set the stain. Instead, let cold water run over the bloodied fabric. Then make a paste with unseasoned meat tenderizer (make sure the ingredients list either “bromelain” or “papain”) and cold water, and put it on the stain. Let it sit for about 30 minutes, then rinse off the tenderizer and wash the garment as usual. Bromelain is derived from pineapple and papain from papaya. Both are enzymes that are good at breaking down protein fibers (which ultimately helps to dissolve blood and tenderize meat).
