How to Remove a Fresh Blood Stain from a Cotton Mattress

Blood on a cotton mattress can look alarming, but if you catch it fresh, you have a good chance of lifting it completely. The key is to act quickly and use cold water only. Hot water will cook the protein in the blood and make the stain permanent. Here’s a practical guide to removing a fresh blood stain from a cotton mattress, with step-by-step instructions and important precautions.

What to Do First

As soon as you notice the blood, blot the area with a clean, dry cloth or paper towel to absorb as much liquid as possible. Do not rub, as this can push the stain deeper into the mattress fibers. After blotting, move on to the treatment method below.

Step-by-Step Removal Method

1. Blot the stain with a dry white cloth or paper towel to soak up excess blood. Press gently and work from the outside toward the center to avoid spreading.
2. Mix a cleaning solution of 1 tablespoon of liquid dish soap (like Dawn) with 2 cups of cold water. Stir gently to combine.
3. Dip a clean white cloth into the solution and wring it out so it’s damp, not dripping.
4. Blot the stain with the damp cloth, working from the edges inward. Continue blotting, turning the cloth to a clean area as it picks up the blood.
5. Rinse the area by blotting with a cloth dipped in plain cold water. This removes any soap residue.
6. Blot dry with a clean, dry towel to absorb as much moisture as possible.
7. Let the mattress air dry completely before putting bedding back on. You can speed up drying with a fan or by opening a window.
