To effectively remove a blood stain from a couch, it is essential to act quickly and use the correct method to avoid setting the stain. The most critical rule is to use only cold water. Hot water will cook the proteins in the blood, causing the stain to become permanent.
Begin by blotting the affected area with a clean cloth dampened with cold water. Gently press on the stain to lift as much of the blood as possible, being careful not to rub, which can spread the stain further into the fabric.
The most commonly recommended solution for breaking down blood is hydrogen peroxide. Before applying it broadly, test a small amount on an inconspicuous spot on the couch to ensure it doesn't cause discoloration. If it is safe for your fabric, apply a small amount of hydrogen peroxide directly to the stain and allow it to fizz. This indicates it is working to lift the stain. After a few moments, blot the area again with a clean, dry cloth. You may need to repeat this process several times.
For tougher stains, you can create a cleaning solution with a drop of mild dish soap, like Dawn, mixed with cold water, or a paste made from baking soda and hydrogen peroxide. Apply the mixture, let it sit briefly, and then blot it away with a cold, damp cloth. Some commercial stain removers like Folex are also reported to be effective on blood. After the stain is gone, you can dab the damp area with a bit of rubbing alcohol to help prevent a water ring from forming as it dries.
