How does one remove bloodstains from bed sheets?

To remove bloodstains from bed sheets, start by rinsing the stained area with cold water to prevent the blood from setting. Next, apply a mixture of mild soap or detergent and cold water directly to the stain, gently blotting with a clean cloth. For stubborn stains, hydrogen peroxide can be used, but test it on a small area first to avoid discoloration. Finally, wash the sheets in cold water and air dry, as heat can set any remaining stain.
