How to Remove Blood from a Mattress

The Logic Verdict

Heat is the enemy. Hot water “cooks” the protein in blood, setting it into the fabric forever. Use cold water and enzymes.

The Science

Blood is protein. Enzyme cleaners (like Nature’s Miracle) are designed to eat proteins.

Step-by-Step Removal

1. Blot: Absorb as much fresh liquid as possible.
2. The Meat Tenderizer: If you don’t have enzyme spray, mix salt and cold water into a paste. Salt dehydrates the blood cells.
3. The Enzyme Soak: Spray the enzyme cleaner liberally. Let it sit for 15 minutes.
4. Blot Again: Press a clean towel into the mattress.
5. Dry: Prop the mattress up or use a fan. You must dry it quickly to prevent mold inside the foam.

What NOT To Do

• NEVER use hot water.
• Do not soak the mattress so deep it never dries.
