How to Remove Blood from Mattress
Blood on a mattress can't be flushed or machine-washed, so you lift it locally without driving moisture into the foam. For a fresh mark the Sleep Foundation uses only a cold, damp cloth — dab, don't rub. A dried mark takes a baking-soda and 3% hydrogen-peroxide treatment left to sit, then air-drying; keep chlorine bleach and heat well away.
Best first move
Dab a fresh mark with a cold, damp white cloth; save the baking-soda and peroxide treatment for a dried stain.
What changes here
No back-rinse and no machine wash — a mattress can't be flushed.
Stop if
Stop before soaking the foam or reaching for chlorine bleach; if the cover unzips, take it off and wash it cold instead.
Before You Treat It
This page exists because the fabric changes the standard blood method. Do the quick checks first; they prevent a useful stain-removal step from becoming a fabric-damage problem.
- Check the care label before using water, bleach, heat or friction on the mattress.
- Test the chosen method on a hidden seam or under-mattress panel; wait until it dries before judging colour or texture change.
- Work from the outside of the stain inward so the mark does not spread into a larger ring.
- Air-dry before applying heat; heat can set a remaining stain and make the next round less effective.
Fabric-Specific Method
- For a fresh mark, dab with a cold, damp white cloth (white so you can read the colour transfer) and stop the moment it stops lifting — never rub. Source note: How to Get Blood Out of a Mattress — Sleep Foundation
- For a dried mark, dust a thin layer of baking soda over the stain, leave it about 15 minutes, then vacuum it up.
- Apply a solution of equal parts cold water and 3% hydrogen peroxide with two or three drops of clear dish soap, dampening the stain.
- Sprinkle a second thin layer of baking soda over the wet area, let it sit a few hours or overnight, then brush it loose, blot away the residue with a clean damp cloth and air-dry fully.
Why This Is Different From the Generic Method
A generic stain page can tell you what usually removes blood. This cell exists only because mattress changes the safer route.
- No back-rinse and no machine wash — a mattress can't be flushed.
- A baking-soda and 3% hydrogen-peroxide treatment replaces the garment oxygen-bleach soak.
- Over-wetting is a real risk — too much liquid in the foam makes drying the next problem.
Do Not Do This
- Keep chlorine bleach and harsh cleaners off a mattress, and never apply heat to set-in blood.
- Don't over-wet — pushing too much liquid into the foam makes drying the bigger problem.
- Test any upholstery or carpet product on a hidden area first, and follow its label.
After the First Round
Judge the result only after the area is dry. A damp fabric can hide a remaining stain, and a fragile surface can look safe while wet but dry with a ring, dull patch or texture change.
- A safe round should reduce the visible blood mark without changing the colour, feel or finish of the mattress.
- If the stain lightens and the fabric looks unchanged after drying, repeat only the gentlest compatible step instead of escalating immediately.
- If colour transfers, the surface roughens, the nap flattens, or a water ring appears, stop the home method and use a professional cleaner.
