Blood Stains on Clothes: Immediately Wash with 'Cold Water + Hydrogen Peroxide/Salt Water'

Principle and Method: Proteins in blood coagulate and denature instantly when exposed to heat (hot water), tightly binding to fabric fibers and causing permanent yellow stains. When you discover a bloodstain, you must rinse it with 'cold water.' If it's been there for a while, you can drip hydrogen peroxide onto the bloodstain. Hydrogen peroxide will break down hemoglobin protein, producing bubbles and quickly fading the bloodstain.
