How To Remove Old Blood Stains From Mattress: Step-by-Step FAQ Guide

If you’re searching for “How To Remove Old Blood Stains From Mattress”, you’re likely dealing with dried, stubborn spots that won’t budge with simple wiping. This guide walks you through what works, what to avoid, and how to treat your mattress gently while lifting those old stains as effectively as possible.

Why Are Old Blood Stains So Hard to Remove from a Mattress?

Blood contains proteins that bind to fabric fibers as they dry, which makes older stains tougher than fresh ones. On a mattress, this is even trickier because you can’t just toss it into a washing machine.

Key challenges include:

  • The stain has had time to set deeply into the fabric
  • You must avoid soaking the mattress
  • Some cleaning methods can damage foams or cover materials if too harsh

The goal is to loosen and dissolve the dried proteins slowly, using gentle, mattress-safe methods.

What Should I Do First Before Treating Old Blood Stains?

Before you start any cleaning method, follow these simple prep steps:

  • Strip the bed: Remove sheets, protectors, and bedding
  • Gently brush the area: Use a soft brush or dry cloth to lift any surface residue
  • Test a small spot: Try your cleaning solution on an inconspicuous area to check for discoloration
  • Avoid hot water: Heat can set blood stains further into the fabric

Taking a few minutes here can prevent damage and improve your results.

How To Remove Old Blood Stains From Mattress: Effective Home Methods

1. Cold Water and Mild Soap

This basic method is often the best first step, especially if the stain is not extremely dark.

  1. Mix cold water with a small amount of mild liquid soap.
  2. Lightly dip a clean cloth into the solution (do not soak it).
  3. Blot the stain gently, working from the outside toward the center.
  4. Use a second cloth dampened with plain cold water to blot away soap residue.
  5. Press a dry towel onto the area to remove excess moisture and let it air-dry completely.

This may not remove very old stains completely, but it can lighten them and prepare the area for stronger methods.

2. Hydrogen Peroxide (Use With Care)

Hydrogen peroxide is a common choice for dried blood but can sometimes lighten fabrics, so always test first.

  1. Use 3% hydrogen peroxide.
  2. Put a small amount directly on the stain or on a cloth.
  3. It may fizz; let it sit for a few minutes while it works on the dried blood.
  4. Blot with a clean, dry cloth—do not rub, as this can spread the stain.
  5. Repeat if needed, then blot with a damp cloth and dry thoroughly.

Because peroxide has a mild bleaching effect, it’s especially important to spot-test on colored or patterned mattress covers.

3. Baking Soda Paste

Baking soda is often used to help lift stains and reduce odors.

  1. Mix baking soda with a small amount of cold water to make a spreadable paste.
  2. Apply a thin layer over the stain.
  3. Let it sit for 30–60 minutes.
  4. Gently wipe away with a damp cloth.
  5. Blot dry and allow the mattress to air out.

This can be used after peroxide or soap to help brighten and refresh the area.

4. Enzymatic Cleaners for Protein Stains

Some household cleaners are formulated specifically for protein-based stains like blood. These are commonly labeled as enzyme or biological cleaners.

  • Follow the instructions on the label carefully.
  • Apply lightly to avoid over-wetting.
  • Allow recommended dwell time, then blot, don’t scrub.
  • Finish by blotting with a damp cloth and drying thoroughly.

These cleaners are often helpful when other methods haven’t fully removed an older stain.

What Should I Avoid When Cleaning Old Blood from a Mattress?

To protect both your mattress and your results, it’s wise to avoid:

  • Hot water or steam: Can set blood stains and affect some foams
  • Harsh scrubbing: Pushes the stain deeper and can damage the fabric
  • Strong bleaches: May discolor the cover or weaken fibers
  • Soaking the mattress: Excess liquid can penetrate deeply and be slow to dry

Gentle, repeated treatments usually work better than one aggressive attempt.

How Can I Dry the Mattress Safely After Cleaning?

After you’ve treated an old blood stain, drying matters as much as cleaning:

  • Press a clean, dry towel firmly to absorb moisture
  • Allow the mattress to air-dry completely before replacing bedding
  • Improve airflow with a fan or open window
  • Avoid direct, intense heat that might damage materials

A dry mattress helps prevent unwanted odors and keeps the sleep surface comfortable.

Can Old Blood Stains Be Completely Removed?

Results can vary. Some old blood stains can be significantly lightened or nearly invisible, while very deep or long-standing stains may always leave a faint shadow.

What you can usually achieve is:

  • A clean, fresh-smelling surface
  • A visible stain that is much less noticeable
  • Confidence that the area has been thoroughly treated

Setting realistic expectations makes the process less frustrating.
