How To Remove Blood Stain On Mattress: Practical, Step‑by‑Step Guide

If you’re searching for “How To Remove Blood Stain On Mattress”, you’re likely dealing with a fresh or dried blood spot and want it gone without damaging your bed. This guide walks through simple, home-friendly methods to clean blood from a mattress safely and effectively.

Why Are Blood Stains Hard To Remove From a Mattress?

Blood stains are often stubborn because they contain protein. When exposed to heat (including hot water), that protein can set into the mattress fibers, making the stain harder to lift.

A mattress also can’t be tossed into a washing machine, so surface treatment is the only option. The key is acting quickly and using the right products in the right way.

What Should I Do First When I Notice a Blood Stain?

Step 1: Act Quickly and Blot, Don’t Rub

If the stain is fresh:

  1. Strip the bed – Remove all bedding so you can see the full extent of the stain.
  2. Use a clean, white cloth or paper towel – Gently blot the area to soak up as much liquid as possible.
  3. Avoid rubbing or scrubbing – This can push the blood deeper into the mattress and spread the stain.
  4. Use only cold water at first – A lightly damp cloth with cold water can help lift fresh blood before it sets.

Avoid hot water, as it can permanently set the stain.

How To Remove Blood Stain On Mattress: Simple Home Methods

Below are commonly used, mattress-safe methods. Always spot test on a small, hidden area first to make sure the fabric or cover doesn’t react poorly.

H2O + Mild Soap Method (For Light or Fresh Stains)

  1. Mix a small amount of mild liquid soap with cold water.
  2. Dip a clean cloth into the soapy water and wring it out so it’s damp, not soaked.
  3. Blot the stain gently, working from the outside in.
  4. Use another cloth with plain cold water to remove soap residue.
  5. Blot dry with a dry towel and let the mattress air-dry completely.

This is often enough for very small, fresh stains.

Hydrogen Peroxide Method (For Dried or Stubborn Stains)

Hydrogen peroxide is commonly used on light-colored mattresses. It can have a mild bleaching effect, so be cautious on darker fabrics.

  1. Use 3% hydrogen peroxide (the typical household strength).
  2. Apply a small amount directly to the stain or onto a cloth and dab it on.
  3. You may see light foaming as it reacts with the blood.
  4. Let it sit for a few minutes, then blot with a clean, dry cloth.
  5. Repeat in small amounts as needed, avoiding over-saturating the mattress.
  6. Finish by dabbing with a cloth dampened in cold water to remove residue, then blot dry.

Baking Soda Paste (Gentle Option for Odor and Stain)

Baking soda can help with light staining and lingering odor.

  1. Mix 1 part baking soda with 2 parts cold water to form a paste.
  2. Apply a thin layer to the stained area.
  3. Let it sit for about 30 minutes.
  4. Gently blot with a clean, damp cloth.
  5. Allow the mattress to air-dry thoroughly.

Enzyme-Based Cleaner (For Persistent Organic Stains)

Enzyme cleaners are designed to break down protein-based stains like blood.

  1. Choose an enzyme cleaner labeled for fabric or upholstery.
  2. Lightly spray or apply to the stain (do not soak the mattress).
  3. Let it sit for the time indicated on the product instructions.
  4. Blot with a clean, dry cloth.
  5. Repeat if necessary and ensure the area dries completely.

Avoid using enzyme cleaners on materials that the manufacturer warns against, such as certain natural fibers. Check your mattress care tag if you’re unsure.

How Do I Dry the Mattress After Cleaning?

Keeping moisture under control is important because a mattress can hold water deep inside:

  • Blot thoroughly with dry towels to remove as much moisture as possible.
  • Allow the mattress to air-dry completely before putting bedding back on.
  • If possible, increase airflow with a fan, open window, or gentle air movement.
  • Avoid direct high heat on one spot, which may damage materials or covers.

What If the Blood Stain Is Old or Has Set In?

Older stains are usually more difficult to remove, but you can still try:

  1. Start with the mild soap and cold water method.
  2. If that isn’t enough, move to hydrogen peroxide or an enzyme cleaner.
  3. Work slowly in layers rather than trying to remove everything at once.

In some cases, a very old or deep stain may never disappear entirely, but it can often be lightened significantly.

Can I Use Bleach or Strong Chemicals on a Mattress?

For most mattresses, bleach and harsh chemicals are not recommended. They can:

  • Damage fabric and foam
  • Discolor the surface
  • Leave strong odors that are hard to remove

Sticking to cold water, mild soap, baking soda, hydrogen peroxide, or gentle enzyme cleaners is usually safer.
