How To Remove Dried Blood Stains From Mattress: Step‑By‑Step FAQ Guide

Finding a dark, dried blood spot on your mattress can be stressful, especially if it has been there for a while. If you’re searching for “How To Remove Dried Blood Stains From Mattress”, this guide walks you through practical methods, what to avoid, and how to protect your bed while you clean.

What makes dried blood stains on a mattress so tricky?

Blood contains proteins that bind to fabric as they dry, which is why old stains are tougher than fresh ones. On a mattress, the challenge is greater because you cannot simply put it in a washing machine.

Two basic rules matter most:

  • Avoid hot water – it can “set” protein stains.
  • Avoid soaking the mattress – too much liquid can lead to odors or damage.

How To Remove Dried Blood Stains From Mattress: What should I do first?

Before using any cleaner, start with gentle, dry steps:

  1. Blot, don’t scrub
    Lightly dampen a clean cloth with cold water and blot the stain to loosen surface residue. Scrubbing can push the stain deeper into the mattress.

  2. Remove any crusted material
    Use the edge of a spoon or a soft brush to lift off any dried, flaky residue. Be gentle so you don’t damage the mattress cover.

  3. Test any cleaner in a hidden area
    Whatever you use next, test it on a small, hidden patch to make sure it does not discolor or damage the fabric.

Which cleaning solutions work best on dried blood stains?

Several common household ingredients can help when learning how to remove dried blood stains from mattress surfaces. You do not need to use all of them—start with one approach and repeat if necessary.

1. Mild soap and cold water

  • Mix a small amount of mild liquid soap with cold water.
  • Dip a cloth in the solution, wring it out well, and blot the stain.
  • Follow with a cloth dampened with plain cold water to remove soap residue.
  • Blot dry with a towel.

This is often enough for lighter or newer dried stains.

2. Baking soda paste

  • Mix baking soda and cold water into a thick paste.
  • Apply a thin layer to the stain and let it sit for 30–60 minutes.
  • Gently wipe away with a damp cloth, then blot dry.

Baking soda can help lift discoloration and reduce odors.

3. Hydrogen peroxide (spot use, light fabrics only)

For light-colored mattress fabrics, some people use a small amount of 3% hydrogen peroxide:

  • Apply a few drops directly to the stain.
  • It may foam—this is normal.
  • Gently blot with a clean cloth.
  • Repeat sparingly until the stain fades, then blot with a damp cloth to remove residue.

Because peroxide can lighten fabric, it is especially important to patch-test and use only on areas where slight lightening is not a concern.

Can I use warm or hot water on dried blood stains?

It is generally recommended to use cold water only. Warm or hot water can cause the proteins in blood to bond more tightly to the fabric, making the stain more permanent. When in doubt, stay with cold water throughout the cleaning process.

How do I avoid soaking or damaging the mattress?

A common concern when figuring out how to remove dried blood stains from mattress surfaces is protecting the inner materials. Too much liquid can cause lingering moisture inside the mattress.

To limit this risk:

  • Use lightly damp cloths, not dripping wet ones.
  • Work in small sections of the stain.
  • Always follow wet steps with dry blotting, pressing with a clean, dry towel to pull moisture out.
  • Allow plenty of time for air drying, ideally in a well-ventilated room.

What if the stain doesn’t come out completely?

Older, set-in stains may never vanish entirely, especially on porous fabrics. You can still:

  • Lighten the stain so it is less visible.
  • Make sure the area is clean and odor-free, which is often more important for comfort and hygiene.
  • Cover the area with a clean mattress protector once it is completely dry.

If the stain is extensive or you are concerned about damaging the mattress, some people choose to consult professional upholstery or mattress cleaning services.

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

Prevention is often easier than removal. Simple steps include:

  • Using a water-resistant mattress protector to keep liquids away from the mattress core.
  • Addressing any spill or stain as soon as possible, before it dries.
  • Keeping clean cloths and mild cleaner available in the bedroom for quick treatment.

✅ Quick Mattress Takeaways

Key points consumers should understand about How To Remove Dried Blood Stains From Mattress

  • Act with cold water only: Hot water can set blood stains and make removal harder.
