How Do You Get Dried Blood Out Of a Mattress? Simple Methods That Work

If you’re searching “How Do You Get Dried Blood Out Of a Mattress”, you’re likely dealing with a stubborn stain that’s already set. The good news: with the right approach, you can usually lighten or remove dried blood stains without damaging your mattress.

Below is a clear, step‑by‑step FAQ to help you understand what to use, what to avoid, and how to protect your mattress while cleaning.

Why is dried blood so hard to remove from a mattress?

Dried blood is tough because it contains proteins that bond to fabric as they dry. On a mattress, this is more challenging because:

  • You can’t just throw it in the washing machine
  • Many mattress covers are thick and absorbent
  • Too much water or harsh scrubbing can damage the foam or filling

That’s why gentle, gradual cleaning with the right ingredients is important.

What should I do before trying to clean the stain?

Before using any cleaner on dried blood:

  1. Strip the bed
    Remove sheets, mattress protectors, and toppers so you can fully see the stain.

  2. Gently loosen dried residue
    Use a soft brush or dry cloth to lift any flaky or crusted blood. Do not scrape hard or use anything sharp.

  3. Blot, don’t soak
    If the area is slightly damp, press with a clean, light-colored cloth to absorb moisture. Avoid hot water, which can set the stain further.

  4. Spot-test your cleaner
    Whatever solution you choose, test it on a small, hidden area of the mattress first to make sure it doesn’t discolor or damage the fabric.

How Do You Get Dried Blood Out Of a Mattress using household ingredients?

Here are common, mattress-safe methods many people use on dried blood stains. Always use cold water, as warm or hot water can make blood more permanent.

1. Cold water and mild soap

This is a good first attempt for lighter stains.

  • Mix a small amount of mild liquid soap with cold water.
  • Dip a clean cloth into the solution and dab the stain gently.
  • Blot with a dry cloth to lift moisture and stain.
  • Repeat: dab with soapy water, then blot dry, until the stain fades.

Avoid over-wetting the mattress. Work slowly and let the area dry between passes if needed.

2. Hydrogen peroxide (for light-colored mattresses)

Hydrogen peroxide is a common go-to for dried blood, especially on white or light fabrics.

  • Use low concentration hydrogen peroxide.
  • Apply a small amount directly to the stain with a cotton ball or cloth.
  • Allow it to foam for a few minutes.
  • Blot with a clean, dry cloth to remove excess liquid and lifted stain.

Repeat in small amounts as needed. On darker fabrics, peroxide may lighten the material, so a spot test is essential.

3. Baking soda paste

Baking soda can help lift stains and reduce odors.

  • Mix 1 part baking soda with 2 parts cold water to form a thin paste.
  • Spread a light layer over the stain.
  • Let it sit for about 30 minutes.
  • Blot with a damp cloth, then blot again with a dry cloth.

Allow the mattress to air dry completely. You can gently vacuum any dried residue later.

4. Salt and cold water solution

Salt can sometimes help draw out protein-based stains.

  • Mix a teaspoon of salt in a cup of cold water.
  • Dab the solution onto the stain with a cloth.
  • Blot the area with a clean, dry cloth to lift moisture and color.

This method tends to work best on fresher dried stains rather than very old ones.

What if the stain doesn’t come out completely?

Dried blood can be stubborn, and some older or deeper stains may only lighten, not vanish entirely. Consider:

  • Repeating the cleaning steps over a few sessions
  • Focusing on lightening the stain rather than perfect removal
  • Using a mattress protector or fitted sheet to keep any remaining discoloration covered

As long as the mattress is fully dry and odor-free, a faint stain is often just a cosmetic issue.

How can I avoid damaging my mattress while cleaning?

To protect your mattress:

  • Avoid soaking – excessive moisture can lead to odors or internal damage
  • Skip harsh scrubbing – this can wear down fabric and push the stain deeper
  • Stay away from strong chemicals not intended for fabrics
  • Dry thoroughly – let the cleaned area air dry completely before making the bed again

A fan or open windows can help speed up drying without direct heat.

How can I prevent future blood stains on my mattress?

Prevention is often easier than deep cleaning. Many sleepers find it helpful to:

  • Use a water-resistant mattress protector
  • Add an easily washable mattress pad or topper
  • Treat any future spills or stains as soon as possible while still fresh

Early action usually leads to much better stain removal results.
