How To Clean Blood Out Of Mattress: Step‑by‑Step FAQ Guide

If you’re searching for “How To Clean Blood Out Of Mattress”, you’re likely dealing with a fresh or dried stain and want it gone without ruining your bed. This guide walks through safe, practical methods to treat blood stains, plus answers to common questions about what works (and what to avoid).

Why is blood so hard to remove from a mattress?

Blood contains proteins that bind to fabric as they dry. On a mattress, this is trickier because:

  • You can’t just throw it in the washing machine
  • Too much liquid can soak deep inside and cause lingering odors
  • The wrong temperature or cleaner can “set” the stain

That’s why acting quickly and using the right technique is important when deciding how to clean blood out of mattress surfaces.

What should I do first if there’s fresh blood on my mattress?

1. Blot, don’t rub

Use a clean, dry cloth or paper towel to gently blot the fresh blood. Press down to absorb; avoid scrubbing.

  • Rubbing can push the blood deeper into the mattress fabric
  • Work from the outside of the stain inward to keep it from spreading

2. Use cold water only

Cold water helps keep proteins from bonding to the fabric.

  • Lightly dampen a cloth with cold water
  • Blot the stained area again; avoid soaking the mattress
  • Repeat with a fresh cloth or clean section as it absorbs the blood

Never use hot water on blood stains, as it can make them more difficult to remove.

How do I clean dried blood out of a mattress?

If the blood has already dried, it usually takes a bit more effort.

Basic method for dried blood

  1. Lightly dampen the stain with cold water to soften it.
  2. Let it sit for 5–10 minutes, then blot with a clean cloth.
  3. If the stain remains, apply a simple cleaning solution (see below), let it work, then blot again.

You may need to repeat the process a few times. Dried stains often fade gradually rather than disappearing in one attempt.

What household solutions can I use on blood stains?

Here are some commonly used, mattress-safe options when applied sparingly:

Mild soap solution

Mix a small amount of mild liquid soap with cold water.

  • Dip a cloth into the soapy water, wring it out
  • Blot the stain gently
  • Follow with a clean damp cloth to remove soap residue

Baking soda paste

Baking soda is often used as a gentle cleaner and deodorizer.

  1. Mix baking soda with cold water into a thin paste.
  2. Spread a light layer over the stain.
  3. Let it sit for 30–60 minutes.
  4. Gently blot with a damp cloth.
  5. Allow the area to air dry completely.

Hydrogen peroxide (for light-colored mattresses only)

Some people use a small amount of hydrogen peroxide on light fabrics to help lift blood stains. It can discolor certain materials, so:

  • Test on a hidden area first
  • Apply only a small amount to the stain
  • Let it bubble for a short time, then blot with a clean, damp cloth
  • Avoid saturating the mattress

If you’re unsure how your mattress fabric reacts, stick to milder options.

How can I dry the mattress safely after cleaning?

Keeping the mattress dry inside is just as important as removing the stain.

  • Use a clean, dry towel to absorb excess moisture
  • Point a fan at the area to speed drying
  • If possible, place the mattress in a well-ventilated, sunny room

Avoid putting bedding back on until the mattress is completely dry to help prevent musty smells or moisture buildup.

What should I avoid when cleaning blood from a mattress?

To protect your mattress, it helps to avoid:

  • Hot water, which can set blood stains
  • Harsh scrubbing, which may damage the fabric and push stains deeper
  • Strong bleach or aggressive chemicals, which can discolor or weaken materials
  • Over-soaking the mattress, which can trap moisture inside

When in doubt, start with the gentlest method and build up only if needed.

Can old or stubborn blood stains be completely removed?

Some old or very deep stains may never disappear entirely, but they can often be lightened significantly.

A few tips for older stains:

  • Repeat gentle cleaning steps over multiple sessions
  • Focus on lightening rather than expecting a brand-new appearance
  • Consider a mattress protector or pad after cleaning to keep the area covered and prevent future stains

How can I prevent future blood stains on my mattress?

Prevention is often easier than stain removal. Simple habits can help:

  • Use a water-resistant mattress protector
  • Spot clean small spills or stains as soon as you notice them
  • Allow plenty of drying time after any cleaning

These steps can make any future “how to clean blood out of mattress” situation faster and less stressful.
