Dried blood on a cotton pillowcase can leave a stubborn dark mark, but you can lift it with cold water, gentle dish soap, and hydrogen peroxide. Here's a practical, surface-safe guide for dried stains, with cotton-specific precautions.

Part 3: Spot-test checklist

Surface Safety for Cotton

Cotton is generally safe to treat with dish soap and hydrogen peroxide, but always test on an inconspicuous area first. Avoid using high concentrations of hydrogen peroxide or leaving it on for too long, as it can weaken the fibers. If the pillowcase has a care label, follow its instructions.

Common Mistakes to Avoid

One common mistake is using hot water or a hot dryer, which sets the stain permanently. Another is rubbing the stain vigorously, which can push it deeper into the fibers. Using bleach on blood can cause a chemical reaction that makes the stain worse and weakens the cotton. Always test any treatment on a hidden area first, and never let hydrogen peroxide dry on the fabric.

When to Consult a Professional

If the stain persists after two or three attempts, or if you notice color fading or fabric damage, it's time to consult a professional cleaner. They have specialized products and techniques that can safely remove stubborn stains without damaging the fabric. This is especially important for delicate or heirloom pillowcases.
