How to clean the underwear stained with aunt's blood? 1. Soak the blood with enzyme-added washing powder. When the blood has not coagulated, the iron in heme exists in the form of ferrous and can be soluble in water. Over time, the ferrous in heme is oxidized into trivalent iron and coagulates with proteins, which makes it difficult to wash off when it is stained on the underwear. At this time, you can soak and clean with enzyme-added washing powder. Add alkaline protease in enzyme-based washing powder to relax and disintegrate the protein in the blood stains and allow it to peel off the underwear.
