How To Clean The Blood Stain From Mattress: Step‑By‑Step Guide & FAQ

Finding a blood spot on your bed can be stressful, but you’re not alone in searching how to clean the blood stain from mattress. With the right approach and common household items, many blood stains can be lightened significantly or removed.

This FAQ-style guide explains why blood stains are tricky, what to do first, and how to treat both fresh and dried stains while keeping your mattress as clean and protected as possible.

Why are blood stains on a mattress so hard to remove?

Blood contains proteins that bind to fabric as they dry. When exposed to heat or hot water, these proteins can “set,” making the stain more difficult to lift.

That’s why a few basic rules matter:

  • Act quickly when possible
  • Avoid hot water (it can set the stain)
  • Blot, don’t scrub, so the stain doesn’t spread or sink deeper

Even older stains may improve with patience and repeated gentle cleaning.

What should I do first when I notice blood on my mattress?

If you’re wondering how to clean the blood stain from mattress effectively, your first steps are crucial:

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

  2. Blot, don’t rub
    Use a clean, light-colored cloth or paper towel. Press gently to absorb any fresh moisture.

    • Do not scrub: this can push blood deeper into the mattress.

  3. Use cold water only
    Lightly dampen a cloth with cold water and blot the area. Avoid soaking the mattress.

These steps help prevent the stain from spreading and make later treatments more effective.

How to clean a fresh blood stain from a mattress

Fresh stains are usually easier to address. Here is a simple, non-harsh approach:

Step-by-step method

  1. Cold water blotting

    • Dip a clean cloth in cold water, wring it out well.
    • Blot the stain gently, lifting rather than scrubbing.

  2. Mild soap solution (optional)

    • Mix a small amount of mild liquid soap with cold water.
    • Lightly dampen a cloth with the soapy water.
    • Blot the stain, then follow with another cloth dampened only with cold water to remove soap residue.

  3. Dry thoroughly

    • Press a dry towel against the area to absorb excess moisture.
    • Allow the mattress to air-dry completely before putting bedding back on. Good airflow helps.

Fresh stains may require a few rounds of blotting, but gentle repetition is often more effective than aggressive scrubbing.

How to clean an old or dried blood stain from a mattress

Older stains usually need a bit more time and patience, but they can often be lightened.

Common gentle methods

Always test any cleaner on a small, hidden area of the mattress first.

  1. Cold water and mild soap (repeated)

    • Even dried stains may respond to repeated cold-water and mild soap blotting.
    • Apply a small amount, blot, then blot again with plain cold water to rinse.

  2. Baking soda paste

    • Mix baking soda with cold water to form a spreadable paste.
    • Apply a thin layer over the stain.
    • Leave it for up to 30 minutes, then gently wipe away with a damp cloth.
    • Blot dry with a towel and allow to air-dry.

  3. Gentle upholstery-safe stain removers

    • Some consumers use non-bleach, fabric-safe stain removers labeled for upholstery.
    • Follow the product directions carefully and avoid oversaturating the mattress.

Deep or very old stains may not disappear completely but can often become much less noticeable.

Can I use hydrogen peroxide or bleach on a blood stain?

Many people think of hydrogen peroxide first for blood, but there are important considerations:

  • Hydrogen peroxide

    • Can help lift blood on some light-colored fabrics.
    • May bleach or discolor certain mattress covers or materials.
    • It’s usually best to use small amounts, applied with a cotton swab or cloth, then blot with cold water.
    • Always test in an inconspicuous spot first.

  • Chlorine bleach

    • Often too harsh for mattresses.
    • Can damage fabric, weaken fibers, and leave strong odors.
    • Generally not recommended for mattress surfaces.

When in doubt, start with the mildest methods and only move to stronger solutions if necessary.

How do I dry the mattress after cleaning a blood stain?

Drying is just as important as cleaning:

  • Avoid soaking the mattress during treatment.
  • After cleaning, press a dry towel over the area to absorb moisture.
  • Allow the mattress to air-dry in a well-ventilated space.
  • If available, a fan or gentle, cool airflow can help.
  • Avoid applying direct heat, which might set any remaining stain.

A thoroughly dry mattress helps prevent lingering odors and moisture issues.

How can I prevent future stains on my mattress?

While no bed is completely stain-proof, a few habits can make cleanup easier:

  • Use a water-resistant mattress protector to create a barrier.
  • Wash bedding regularly so any marks are noticed quickly.
  • Address spills or stains as soon as you see them, before they dry fully.

These steps don’t stop accidents from happening but can make dealing with them much simpler.
