How To Get Dried Blood Out Of Mattress: Simple Methods That Actually Help
If you’re searching for “How To Get Dried Blood Out Of Mattress”, you’re likely dealing with a stubborn stain that’s already set. The good news: with the right approach and some patience, many dried blood stains can be noticeably lightened or removed.
This guide walks through practical, home-friendly methods to clean dried blood from a mattress while protecting the fabric and materials as much as possible.
Why Is Dried Blood So Hard To Remove From a Mattress?
Blood contains proteins that bond to fabric as they dry. On a mattress, that’s even trickier because:
- You can’t just toss it in a washing machine
- Many mattresses have multiple layers and materials
- Too much moisture can lead to odors or damage
That’s why removing dried blood from a mattress is usually a step-by-step process rather than a quick wipe.
First Steps: What Should I Do Before Cleaning?
Before you start any stain treatment:
Blot, don’t scrub
If there’s any remaining residue, gently blot with a dry, clean cloth. Scrubbing can push the stain deeper.Use cold water only
Warm or hot water can “cook” the proteins and set the stain further. Cold water is safer for blood stains.Check your mattress care tag
Some materials are more sensitive to moisture or certain cleaners. Follow any warnings on the label.Work on a small test area
Whatever solution you use, test a tiny hidden spot first to make sure it doesn’t discolor or damage the fabric.
How To Get Dried Blood Out Of Mattress: Step‑By‑Step Methods
H2O + Patience: Can Cold Water Alone Help?
For very light, dried stains:
- Lightly dampen a clean cloth with cold water (not soaking wet).
- Blot the stain gently, lifting outward from the center.
- Repeat with fresh sections of the cloth as the stain transfers.
- Let the mattress air dry completely.
This can sometimes fade recent or mild stains, but older or darker marks usually need more help.
Enzymes & Gentle Cleaners: What Works on Dried Blood?
Most people use one or more of these common household options:
1. Mild Soap Solution
- Mix a small amount of gentle liquid soap with cold water.
- Dip a cloth into the solution and wring it out so it’s just damp.
- Blot the stain—avoid saturating the mattress.
- Follow with a clean, damp cloth (cold water only) to remove soap residue.
- Allow to dry fully.
This is often a good first “upgrade” after trying plain water.
2. Enzyme-Based Cleaner (For Protein Stains)
Some general household cleaners are formulated for protein-based stains like blood. When using one:
- Apply it lightly to a cloth, not directly to the mattress.
- Blot the stained area gently.
- Let it sit for the recommended time on the product instructions.
- Blot with a clean, damp cloth to remove any residue.
- Dry thoroughly.
Enzyme-based formulas are often used because they help break down the proteins in dried blood.
3. Baking Soda Paste
For lingering discoloration:
- Mix baking soda with a little cold water to make a spreadable paste.
- Apply a thin layer to the stain.
- Let it sit for 30–60 minutes.
- Gently scrape off the dried paste and vacuum the area.
This method is often used to deodorize as well as lighten stains.
Can Hydrogen Peroxide Be Used on a Mattress?
Some people use diluted hydrogen peroxide on light-colored fabrics to help lift blood stains, because it can have a mild bleaching action.
If you consider this:
- Test a very small hidden spot first.
- Use a low concentration and apply sparingly with a cloth or cotton swab.
- Blot, do not soak.
- Follow with a clean, damp cloth to remove residue.
On darker fabrics or delicate materials, hydrogen peroxide may lighten the color, so caution is important.
How Do I Dry the Mattress After Cleaning?
After treating dried blood, make sure the mattress dries completely to avoid odors or moisture buildup:
- Open windows or use a fan for air circulation
- Avoid using direct heat in one spot for a long time
- Do not put sheets back on until the surface feels dry to the touch
If you have a removable mattress cover, allow it to dry fully before replacing it.
What If the Dried Blood Stain Won’t Come Out Completely?
Some older or very dark stains may not disappear entirely, even after several attempts. In those cases, you can still:
- Lighten the stain so it’s less noticeable
- Cover the area with a clean, protective mattress cover or pad
- Focus on cleanliness and odor control, even if a faint mark remains
It’s also reasonable to stop scrubbing at some point. Overworking the fabric may do more harm than the stain itself.
How Can I Prevent Future Blood Stains on a Mattress?
While accidents can’t always be avoided, you can make cleanup easier:
- Use a waterproof or water-resistant mattress protector
- Address any spills or stains as soon as possible, before they dry
- Keep gentle cleaning supplies on hand so you can act quickly
Protective layers often make the difference between a quick wash and a deep mattress clean.
