# 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

1. 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
2. For a dried mark, dust a thin layer of baking soda over the stain, leave it about 15 minutes, then vacuum it up.
3. Apply a solution of equal parts cold water and 3% hydrogen peroxide with two or three drops of clear dish soap, dampening the stain.
4. 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.

## When to Use the Full Guide

Use this page for the fabric exception. Use the full blood guide when you need the broader method: timing, washable-fabric instructions, set-in stain rules, product choices, repeated rounds and related stain types.
