How to Remove a Dried Blood Stain from a Cotton Mattress
A dried blood stain on a cotton mattress can be stubborn, but you can lift it with cold water, dish soap, and baking soda. Here's a practical guide for dried stains, with cotton-specific precautions.
Discovering a dried blood stain on your cotton mattress can be frustrating. Whether from a minor cut or a nosebleed, blood is a protein-based stain that becomes more difficult to remove once it dries. But with the right approach and a few household staples, you can lift the stain without damaging the mattress fabric.
Why Dried Blood Is Tricky
Blood contains proteins that bind to fabric fibers. When blood dries, these proteins set, making the stain harder to remove. Heat can permanently set the stain, so it's crucial to avoid hot water and heat sources until the stain is gone.
