How To Remove Blood Stain From a Mattress: Simple FAQ Guide

If you’re searching for how to remove blood stain from a mattress, you’re likely dealing with a fresh spill or a dried spot you just discovered. This guide walks through safe, practical methods, common questions, and what to avoid so you can clean your mattress without damaging it.

Why Do Blood Stains Stick to Mattresses?

Blood contains proteins that bond to fabric fibers as they dry. On a mattress, this can lead to:

  • Persistent brown or reddish stains
  • Odors if the area stays damp
  • Discoloration that becomes harder to treat over time

Understanding this helps explain why acting quickly with the right technique makes such a big difference.

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

Step 1: Blot, Don’t Rub

Use a clean, dry, white cloth or paper towel to gently blot up as much blood as possible.

  • Press down to absorb; do not scrub, which can push blood deeper into the mattress.
  • Work from the outside of the stain inward to avoid spreading it.

Step 2: Use Cold Water Only

Cold water helps prevent the blood proteins from setting.

  1. Lightly dampen a clean cloth with cold water.
  2. Blot the stain again, lifting rather than rubbing.
  3. Repeat with fresh sections of the cloth until no more blood transfers.

Avoid hot or warm water at this stage, as it can set the stain permanently.

How To Remove Blood Stain From a Mattress (Step-by-Step Methods)

H2O + Mild Soap Method (Best for Fresh Stains)

  1. Mix a small amount of mild liquid soap with cold water to create light suds.
  2. Dip a clean cloth in the soapy water, wring it out well.
  3. Gently blot the stained area.
  4. Follow with a cloth dampened with plain cold water to remove soap residue.
  5. Blot with a dry towel to remove excess moisture.

Baking Soda Method (Helps Lift and Deodorize)

  1. Lightly dampen the stain with cold water (do not soak).
  2. Sprinkle a thin, even layer of baking soda over the area.
  3. Let it sit for at least 30 minutes, or longer if the stain is older.
  4. Gently vacuum or brush off the dried baking soda once it’s fully dry.

This method is often used as a second step after initial blotting.

Hydrogen Peroxide (Use With Caution)

Hydrogen peroxide can help lift tougher stains but may lighten fabric, especially dark materials. Always test a small, hidden area first.

  1. Put a small amount of 3% hydrogen peroxide on a cotton ball or cloth.
  2. Dab it onto the stain; you may see some gentle foaming.
  3. Blot with a clean, dry cloth as the stain lifts.
  4. Follow with a slightly damp cloth (cold water) and blot dry.

Avoid soaking the mattress; too much liquid can seep deep inside and be slow to dry.

What If the Blood Stain Is Already Dry?

Dried stains usually need a bit more patience, but many can still be reduced:

  1. Loosen the stain by gently dabbing with a cloth dampened in cold water.
  2. Use the mild soap method or baking soda method described above.
  3. For stubborn spots, follow with careful use of hydrogen peroxide, especially on light-colored fabrics.

It can help to repeat the process in short cycles rather than trying to remove everything in one attempt.

Can I Use Hot Water, Bleach, or Strong Cleaners?

  • Hot water: Often sets blood stains and makes them harder to remove.
  • Bleach: Can damage mattress materials and cause yellowing or discoloration.
  • Harsh chemicals: Strong cleaners may break down fabrics, affect mattress comfort, or leave strong odors.

For most mattresses, gentle, cold-water-based methods are safer and more suitable.

How Do I Dry the Mattress After Cleaning?

Keeping your mattress dry is important to avoid lingering moisture.

  • Blot with dry towels until little moisture remains.
  • If possible, allow the mattress to air dry with good airflow in the room.
  • A fan can help speed drying.
  • Avoid covering the area with bedding until it is fully dry to the touch.

How Can I Prevent Future Blood Stains on My Mattress?

While accidents happen, a few simple steps can make cleanup easier next time:

  • Use a water-resistant mattress protector as a barrier.
  • Keep extra sheets and protectors available so you can strip the bed quickly.
  • Try to treat any spills as soon as you notice them, before they dry.
