How To Clean Blood Off Mattress: Simple Steps That Really Work

If you’re searching for “How To Clean Blood Off Mattress”, you’re likely dealing with a fresh stain, a dried one, or even a recurring spot you’ve just noticed. The good news: with the right approach, you can often remove or significantly reduce blood stains without damaging your mattress.

This FAQ-style guide walks you through what to do, what to avoid, and how to handle both fresh and dried blood on a mattress.

Why is blood so hard to remove from a mattress?

Blood contains proteins that bond with fabric and mattress fibers as it dries. If you use the wrong temperature or product, you can actually “set” the stain, making it more permanent.

A few basics to keep in mind:

  • Act quickly when possible – fresh stains are easier to treat.
  • Avoid hot water, which can make the stain tougher to remove.
  • Work gently – scrubbing too hard can push the stain deeper into the mattress.

How To Clean Blood Off Mattress: Step-by-step for fresh stains

1. Blot, don’t scrub

  1. Strip the bedding and set it aside to wash separately in cold water.
  2. Use a clean, dry cloth or paper towel to gently blot the blood.
  3. Work from the outside of the stain toward the center to avoid spreading.

Do not rub or scrub at this stage. That can push the blood further into the mattress.

2. Apply a cold water solution

  1. Fill a bowl with cold water.
  2. Lightly dampen a clean cloth – it should be damp, not soaking wet.
  3. Dab the stained area, then blot with a dry cloth.
  4. Repeat as needed until the stain starts to lighten.

Keeping moisture under control helps protect the mattress from mold, mildew, or lingering dampness inside.

3. Use a mild cleaning agent (if needed)

If cold water alone doesn’t work, you can try a gentle cleaner, such as:

  • A small amount of mild liquid soap mixed with cold water
  • A baking soda paste (3 parts baking soda to 1 part cold water)

Apply with a cloth, let it sit briefly, then blot with a clean damp cloth to remove residue. Always test in a small hidden area first to make sure there’s no discoloration.

How do I remove dried blood from a mattress?

Dried blood can be more stubborn, but you can still improve or reduce the stain.

1. Loosen the dried residue

Gently use a soft brush or dry cloth to loosen any crusted material on the surface. Avoid anything sharp that could tear the fabric.

2. Rehydrate with cold water

  1. Dampen a cloth with cold water and press it onto the stained area.
  2. Let it sit for a few minutes to soften the dried blood.
  3. Blot with a clean, dry cloth.

3. Try a stain-fighting solution

For tough, dried stains, consumers often rely on:

  • A baking soda and cold water paste left on the stain for about 30 minutes, then blotted away.
  • A small amount of gentle, color-safe stain remover designed for fabrics (always tested on an inconspicuous spot first).

Work slowly and patiently. Multiple light treatments are usually safer for the mattress than one aggressive attempt.

What should I avoid when cleaning blood off a mattress?

Some common mistakes can make stains worse or damage the mattress:

  • Hot water: Can cause blood proteins to set permanently.
  • Harsh chemicals: Strong bleaches or solvents may discolor fabric or break down materials.
  • Soaking the mattress: Excess water can seep into the core, leading to odors or internal damage.
  • Scrubbing aggressively: Can spread the stain and rough up the fabric.

If in doubt, start with the mildest method and work up gradually.

How do I dry the mattress after cleaning?

Once you’ve removed as much of the stain as possible, it’s important to dry the mattress thoroughly:

  • Press a dry towel over the area to absorb extra moisture.
  • Allow the mattress to air dry completely before putting sheets back on.
  • If available, use a fan or open window to speed up drying.
  • Avoid using high heat directly on the mattress surface.

A fully dry mattress helps prevent lingering smells and moisture issues.

Will the stain come out completely?

Results vary based on:

  • How long the blood has been on the mattress
  • The type of mattress fabric and materials
  • How much and how often the stain has been treated

In many cases, careful cleaning can make the stain barely noticeable. Even if a faint mark remains, removing as much residue as possible helps maintain a cleaner, fresher sleep surface.

How can I prevent blood stains on my mattress in the future?

Some simple habits can make cleanup easier next time:

  • Use a water-resistant mattress protector to create a barrier against spills and stains.
  • Treat any accidents or leaks quickly before they dry.
  • Wash bedding regularly so stains are less likely to reach the mattress at all.

These steps can extend the life of your mattress and reduce the need for deep stain removal.
