How To Clean Blood From a Mattress: Simple Steps That Really Work

If you’re searching for how to clean blood from a mattress, you’re likely dealing with a fresh accident or an old, stubborn stain. Mattresses are not easy to toss in the wash, but with the right approach you can usually remove or greatly reduce blood stains without damaging the fabric or foam.

This FAQ-style guide walks you through safe, practical methods and answers the most common questions people have about blood stains on mattresses.

Why is blood so hard to clean from a mattress?

Blood is rich in proteins that bind to fabric fibers as they dry. On a mattress, where you can’t easily soak or scrub aggressively, those proteins can set deep into the surface.

Two things make a big difference:

  • Temperature: Hot water can “cook” proteins and set the stain.
  • Timing: The fresher the stain, the easier it is to remove.

For this reason, most mattress cleaning methods for blood focus on cool water, gentle blotting, and patience.

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

Start as quickly as possible:

  1. Remove bedding
    Strip sheets, protectors, and mattress covers and treat them separately in cool water.

  2. Blot, don’t scrub
    Use a clean, white cloth or paper towel to blot up as much liquid as you can. Press down gently; avoid rubbing, which can push blood deeper into the mattress.

  3. Use cool water only
    Lightly dampen a cloth with cold water and continue blotting the stain from the outside in. This can lift a surprising amount of fresh blood before you even add a cleaner.

Avoid soaking the mattress. Too much moisture can lead to lingering dampness inside the foam or padding.

How To Clean Blood From a Mattress with common household solutions

Here are simple, widely used methods that can work on most mattresses. Always spot test a small hidden area first to check for discoloration.

1. Mild soap and cold water

This is often enough for small, fresh stains.

  1. Mix a small amount of gentle liquid soap with cold water.
  2. Dip a cloth into the soapy water and blot the stain.
  3. Follow with a separate cloth dampened with plain cold water to rinse.
  4. Blot dry with a towel.

2. Salt or baking soda paste

Some people prefer a gentle paste for extra pulling power.

  1. Mix salt or baking soda with cold water to form a paste.
  2. Spread a thin layer over the stain and let it sit for about 30 minutes.
  3. Gently wipe away the paste with a damp cloth.
  4. Blot dry.

3. Hydrogen peroxide (use with care)

Hydrogen peroxide is commonly used on white or very light-colored mattress fabrics, but it may lighten darker materials.

  1. Place a small amount of 3% hydrogen peroxide on the stain.
  2. It will usually foam; gently blot with a clean cloth as it works.
  3. Repeat as needed, then follow with a cold, damp cloth to remove residue.
  4. Blot dry thoroughly.

Use sparingly to avoid over-wetting or lightening the fabric.

How do I remove dried or old blood stains?

Dried blood is more stubborn, but it can still improve with a bit of patience.

  1. Re-moisten the stain
    Lightly dampen the area with cold water to soften the dried blood.

  2. Apply a gentle cleaner
    Use one of the methods above (soap solution, salt or baking soda paste, or careful use of hydrogen peroxide).

  3. Let it sit
    Allow your chosen cleaner to sit on the stain for 15–30 minutes.

  4. Blot repeatedly
    Press with a clean cloth, lift, and repeat. You may need multiple rounds rather than one strong treatment.

With older stains, the goal is often significant fading rather than perfect removal.

How can I dry the mattress safely after cleaning?

Proper drying is important to avoid trapped moisture.

  • Blot out as much liquid as possible with dry towels.
  • Allow the mattress to air dry completely before making the bed.
  • If available, point a fan at the spot or open windows to increase airflow.
  • Avoid direct high heat applied closely (like a hot hairdryer blasting one spot), as this can be harsh on certain mattress materials.

Will cleaning blood from a mattress damage it?

Most mattresses handle light spot cleaning well when you:

  • Use minimal liquid
  • Stick to cool water
  • Avoid harsh scrubbing or strong chemicals
  • Follow any care instructions provided with the mattress

Over-soaking or using very strong cleaners can risk discoloration or interior damage, so gentle methods are usually the safest choice.
