How To Get Blood Off Of a Mattress: Simple Steps That Really Work

If you’re searching for “How To Get Blood Off Of a Mattress,” you’re likely dealing with a fresh stain or a dried one that won’t budge. This guide walks you through safe, mattress-friendly methods, explains what to avoid, and answers the most common questions people have about cleaning blood from a mattress.

Why Blood Stains Are Tricky (and What That Means for Cleaning)

Blood contains proteins that can set into fabric and foam, especially when exposed to heat. That’s why hot water and harsh scrubbing can make the stain worse.

Understanding this helps you choose the right approach: cool water, gentle blotting, and mild cleaners are your best tools when figuring out how to get blood off of a mattress.

How To Get Blood Off Of a Mattress: Step-by-Step

1. Act Quickly if the Stain Is Fresh

Fresh stains are usually easier to remove.

  1. Strip the bed and wash bedding separately.
  2. Blot with a clean cloth dipped in cold water.
    • Work from the outside of the stain inward.
    • Do not rub, as this can spread and push the blood deeper.
  3. Keep blotting until no more blood transfers to the cloth.

If the stain remains, move on to a gentle cleaner.

2. Use a Mild Cleaning Solution

Common at-home options include:

  • Mild soap and cold water
    Mix a few drops of gentle liquid soap with cold water. Lightly dab the stain with a cloth, then blot with a dry cloth to remove excess moisture.

  • Paste of baking soda and cold water
    Spread a thin layer over the stain, let it sit for about 30 minutes, then gently wipe away with a damp cloth and blot dry.

  • Salt and cold water
    Make a loose paste, apply to the stain, let it rest briefly, then dab away with a damp cloth.

Always test any cleaner on a small, hidden area first to check for discoloration or damage.

How Do You Remove Dried Blood From a Mattress?

Dried blood can be more stubborn, but the same principles apply.

  1. Lightly dampen the area with cold water.
    This can help soften the dried blood.
  2. Apply a gentle cleaning solution (such as the baking soda paste above).
  3. Let it sit longer than you would for a fresh stain—often 30–60 minutes.
  4. Blot with a clean, damp cloth, then blot dry with a towel.

You may need to repeat the process several times for older or deeper stains. Patience and gentle repetition often work better than aggressive scrubbing.

What Should You Avoid When Cleaning Blood Off a Mattress?

To protect both your mattress and your chances of removing the stain, avoid:

  • Hot water (it can set the stain)
  • Steam cleaners on the blood spot
  • Bleach or very harsh chemicals on most mattress fabrics and foams
  • Soaking the mattress or pouring water directly on it
  • Scrubbing vigorously, which can spread and drive the stain deeper

How Do You Dry the Mattress After Cleaning?

Moisture trapped inside a mattress can cause long-term issues, so drying is essential.

  • Blot thoroughly with a dry, absorbent towel.
  • Use a fan or open windows for better airflow.
  • If possible, elevate the mattress slightly so air can circulate around the damp area.
  • Allow it to dry fully before replacing sheets.

Avoid using high heat directly on the mattress surface.

Can All Mattress Types Be Cleaned the Same Way?

Most general guidelines for how to get blood off of a mattress are similar, but a few differences matter:

  • Memory foam and foam mattresses
    These absorb liquid quickly, so use minimal moisture and blot frequently.
  • Hybrid or innerspring mattresses
    These can also be sensitive to soaking; focus on surface cleaning and fast drying.
  • Mattress covers and protectors
    If you use a protector, remove and wash it according to its care label. Often, it catches most of the stain before it reaches the mattress.

Always check your mattress care instructions if available.

📝 ✔️ Quick Mattress Takeaways

Key points to understand about How To Get Blood Off Of a Mattress:

  • Use cold water only – heat can set blood stains permanently.
  • Blot, don’t scrub – scrubbing spreads the stain and pushes it deeper.
  • Start with gentle cleaners – mild soap, baking soda paste, or salt and water can be effective.
  • Treat fresh stains as soon as possible – they’re much easier to remove than dried ones.
  • Avoid soaking the mattress – too much moisture is hard to dry and can cause other problems.
  • Repeat light treatments if needed – slow and gentle methods are often more successful.
  • Dry thoroughly with towels and airflow before making the bed again.

Handling an unexpected blood stain is stressful, but with the right approach, how to get blood off of a mattress becomes manageable. By working with cool water, mild cleaners, and careful blotting—not harsh scrubbing or heat—you give yourself the best chance of lifting the stain while keeping your mattress in good shape for years of comfortable sleep.
