How To Remove Blood Stains From a Mattress: Practical FAQ Guide

If you’re searching for how to remove blood stains from a mattress, you’re likely dealing with a fresh spill or an old, dried stain you’ve just noticed. This guide walks you through safe, practical methods to clean blood from a mattress, plus answers to common questions about what works, what doesn’t, and how to protect your bed.

Why Are Blood Stains on a Mattress So Hard To Remove?

Blood contains proteins that bind to fabric and mattress fibers as they dry. Hot water or harsh scrubbing can “set” the stain, making it much more difficult to remove. That’s why the temperature of the water and the products you choose are important.

Key idea: Always start with cold water and gentle blotting, not scrubbing or hot water.

What Should I Do First When I Notice Blood on My Mattress?

Step 1: Act Quickly (If the Stain Is Fresh)

  1. Strip the bedding
    Remove sheets, mattress protectors, and blankets so you can see the full stain.

  2. Blot, don’t rub
    Use a clean, light-colored cloth or paper towels to blot up as much blood as possible. Press gently; avoid rubbing, which can push the stain deeper.

  3. Use cold water
    Lightly dampen a cloth with cold water only and continue blotting. Cold water helps dilute the blood without cooking the proteins into the fabric.

Step 2: Choose a Cleaning Method

Below are common, mattress-safe approaches for how to remove blood stains from a mattress. Always test any solution on a small, hidden area first.

Which Cleaning Methods Work Best on Blood Stains?

1. Mild Soap and Cold Water

This is often enough for small, fresh stains.

  • Mix a few drops of mild liquid soap with cold water.
  • Dip a clean cloth in the solution and gently dab the stain.
  • Blot with a dry cloth to absorb moisture.
  • Repeat until the stain lightens, then allow the mattress to air dry completely.

2. Baking Soda Paste

Useful for fresh or slightly dried stains and for deodorizing.

  • Mix 1 part cold water with 2 parts baking soda into a spreadable paste.
  • Apply a thin layer to the stained area.
  • Let it sit for about 30 minutes.
  • Gently wipe off with a damp cloth, then blot dry with a towel.
  • Let the mattress air dry.

3. Hydrogen Peroxide (Use With Caution)

Hydrogen peroxide can be effective on tougher stains, but it may lighten fabric or leave a faint ring, especially on dark materials.

  • Use 3% hydrogen peroxide (the common household strength).
  • Apply a small amount directly to the stain or onto a cloth.
  • You may see foaming as it reacts with the blood.
  • Gently blot and repeat if needed.
  • Once the stain lifts, blot with a damp cloth to remove residue, then dry thoroughly.

Because of the bleaching risk, this approach is best for light-colored mattresses and older stains that haven’t responded to gentler methods.

How Do I Remove Dried or Old Blood Stains From a Mattress?

Older stains can be more stubborn but can often be lightened significantly.

  1. Loosen dried residue
    Gently scrape the surface with a soft brush or cloth to remove any crusted blood.

  2. Rehydrate with cold water
    Lightly dampen the area with cold water to soften the stain. Do not soak the mattress.

  3. Use a cleaning solution
    Try, in this order:

    • Mild soap and cold water
    • Baking soda paste
    • A small amount of hydrogen peroxide if the first two don’t work

  4. Be patient
    Old stains may need several short treatments rather than one intense cleaning.

Can I Use Hot Water, Steam, or Strong Chemicals?

  • Hot water: Generally not recommended. It can set blood stains and make them more permanent.
  • Steam cleaners: These use heat and moisture, which may drive the stain deeper and potentially damage some mattress materials.
  • Bleach or harsh chemicals: These can discolor fabrics, weaken materials, and leave strong odors. They are usually not ideal for mattresses.

Sticking to cold water and gentle cleaners is usually safer and still effective.

How Can I Dry the Mattress After Cleaning?

Mattresses should never stay damp for long.

  • Open windows or use a fan to increase air circulation.
  • If possible, place the mattress in a well-ventilated area.
  • You can use a hair dryer on a cool or low setting, held at a distance, to speed up drying.
  • Ensure the area is completely dry before putting sheets back on to reduce the chance of odors or moisture buildup.

How Do I Prevent Future Blood Stains on My Mattress?

While accidents happen, some simple steps can make cleanup easier:

  • Use a water-resistant mattress protector as a barrier.
  • Choose washable, protective layers (like fitted protectors or pads) under your sheet.
  • Treat stains as soon as you notice them to improve your chances of full removal.
