A blood stain on your newly bought mattress- maybe it happened during the night, or maybe you just noticed it this morning.
Either way, panic sets in fast, and your mind jumps straight to one question: is this mattress ruined now? Take a deep breath; it’s not.
Most stains, even the deep red kind, can be treated at home with things you already own.
This blog shows you exactly how to get blood out of a mattress, step by step, so you can stop staring at it and start fixing it.
What to Do The Moment You Spot a Blood Stain?
If you spot a blood stain, grab a clean cloth and some cold water right away. Blood comes out much easier while it’s still wet, so don’t wait around.
It’s best to tackle it the moment you see it, before it has time to dry into the mattress fibers. Hot water makes the stain stick to the fabric while cold water helps loosen it up instead.
This one small choice can make a huge difference in how easy the stain is to remove later. Also, don’t rub the stain; that just pushes the blood deeper in and spreads it wider.
Instead, gently press the cloth onto the spot and lift it back up. Start from the outer edges and work your way toward the center.
How to Get Blood Out of a Mattress?
Dried blood needs more than a damp cloth. It has already bonded to the mattress fibers, so treating it takes a few extra steps done in the right order.
Step 1: Scrape off The Dried Particles First
Use the edge of a dull knife, a spoon, or an old credit card to gently lift away any flaking or crusted blood. Work in short strokes and brush the loose bits into a trash bag as you go.
Skipping this step means you end up rubbing dried particles further into the fabric once you add liquid.
If the stain has hardened into a thick crust, flex the fabric gently from the back side first to loosen it before scraping.
Step 2: Test The Solution on a Hidden Spot
Dab a small amount of your cleaning mix on a corner of the mattress that stays hidden, like near the edge under a fitted sheet.
Wait five minutes and check for any discoloration or fabric damage. This ten-second check protects the rest of the mattress from bleaching or texture changes.
Step 3: Mix a Hydrogen Peroxide Paste
Combine a quarter cup of hydrogen peroxide with two tablespoons of cornstarch and one tablespoon of baking soda in a small bowl, and stir until it forms a thick paste.
Spread a thin layer directly over the stain; you will notice light fizzing, which is normal and means the peroxide is breaking the stain down.
Bonus Tip: Always test the paste on a hidden corner of the fabric first, since hydrogen peroxide can lighten certain dyes and delicate materials.
Step 4: Let It Sit, then Blot and Rinse
Leave the paste on for about ten minutes, then blot it away with a damp cloth.
Rinse the area with a fresh cloth dipped in cold water, switching to a clean section often so you are not spreading residue back onto the mattress.
Press rather than rub while rinsing, since scrubbing at this stage can push moisture deeper into the mattress padding.
Step 5: Dry The Mattress Completely Before Use
Press a dry towel firmly over the spot to soak up leftover moisture, then point a fan at the area or set the mattress near an open window.
Wait until it feels completely dry to the touch, usually a few hours, before putting sheets back on. A mattress left damp underneath can grow mildew, which is a harder problem than the stain itself.
When you’re in a hurry, use a hairdryer on the cool setting, held a few inches away, to speed up drying.
Household Remedies for Removing Dried Blood Stains
You do not need a special stain remover to treat blood on a mattress. These items are already sitting in most kitchens, and each one works a little differently.
| Remedy | What You Need | How to Use It | Best For |
|---|---|---|---|
| Salty Soak Paste | Salt, splash of cold water | Paste on, sit 30 min, scrape and blot | Small, fresh stains |
| Tenderizer Solution | Tenderizer, cold water | Rub in, sit 30 min, rinse and blot | Set-in stains a few days old |
| Fizzing Vinegar Lift | Equal parts vinegar and baking soda | Soda first, vinegar on top, sit 10 min, blot | Colored or delicate fabric |
| Gentle Soap Dab | Dish soap, cold water | Dab on, blot in small circles, rinse | Light or partial stains |
| Dry Cornstarch Paste | Cornstarch, cold water | Paste on, let dry fully, brush off | Memory foam mattresses |
What Not to Do When Cleaning a Blood Stain
A few common habits can turn a simple stain into a permanent one. Avoid these while treating a blood stain on your mattress.
- Hot Water: Heat sets the protein in blood into the fabric, locking the stain in instead of lifting it out.
- Rubbing: Scrubbing back and forth pushes blood deeper into the fibers and spreads it wider than the original spot.
- Oversoaking: Too much liquid seeps past the cover into the padding, where it can cause mildew that is harder to fix than the stain.
- Skipping The Dry Time: Making the bed while the mattress is still damp traps moisture underneath and invites mold growth.
- Bleach on Colored Fabric: Bleach strips color from mattress covers and can weaken the fibers, even when it lifts the stain.
- Ignoring Dried Particles: Adding liquid straight onto crusted blood without scraping it off first just smears dried residue further into the mattress.
How Do You Get Rid of The Smell After a Blood Stain?
Even after the stain looks gone, a faint smell can hang around. That smell comes from tiny bits of blood still stuck deep in the mattress fibers, way past what your eyes can see.
Baking soda is your best friend here. Once the mattress is fully dry, sprinkle a thin, even layer over the whole spot, let it sit for a few hours, or overnight if the smell is strong.
Baking soda works like a sponge for odors, pulling smell out of the fibers instead of just covering it up. After that, vacuum the area slowly using the upholstery attachment.
If you want a more thorough refresh beyond just the smell, our guide on how to deep clean a mattress covers the full process.
Open a window while you do this. Fresh air moving through the room speeds up the process and carries the last of the smell right out with it.

How to Protect Your Mattress from Future Stains
A little prevention saves you the whole cleaning process next time. These steps cover different angles, from blocking stains outright to catching them early.
1. Use a Waterproof Mattress Protector
A mattress protector creates a sealed barrier between your body and the mattress itself, so any spill or stain stays on a removable cover instead of soaking into the padding underneath.
2. Keep a Stain Kit Near Your Bedroom
Store a small cloth, hydrogen peroxide, and baking soda in a bedroom drawer or nearby closet. Having supplies within reach means you can treat a fresh stain in minutes instead of scrambling to find them later.
Hydrogen peroxide is generally safe once diluted and rinsed off, but keep the bottle itself out of reach from kids and ventilate the room while the mattress dries.
3. Choose a Protector with a Breathable Top Layer
Some waterproof covers trap heat and make you sweat more, which raises the odds of stains and speeds up wear. A breathable layer blocks liquid while still letting air pass through.
4. Wash The Protector Every Two Weeks
A protector only works if it stays clean. Regular washing keeps oils, sweat, and skin cells from building up, which also keeps your mattress smelling fresh underneath.
5. Rotate Your Mattress Every Three Months
Rotating spreads out wear and reduces the chance that one area absorbs repeated stains or pressure, since the same spot is not always facing up.
6. Treat Sheets Separately from The Mattress
Wash sheets right away with a stain remover before the blood dries into the fabric. Sheets are far easier to launder than a mattress, so catching it there stops most stains before they ever reach the surface below.
7. Check Your Mattress Warranty Terms
Many warranties become void if a mattress has visible stains, since manufacturers cannot inspect for defects underneath them. Keeping the surface clean protects your ability to make a claim later if something goes wrong with the mattress
Conclusion
A blood stain feels like a disaster in the moment, but it rarely has to be. Fresh spots lift out with cold water and a little patience.
Older, dried stains take more work, yet a peroxide paste, some scraping, and the right pantry remedy can still bring your mattress back to normal.
The real trick is acting fast, blotting instead of scrubbing, and letting the mattress dry before you cover it again.
Now that you know how to get blood out of a mattress, keep a small stain kit nearby for next time. Grab a mattress protector today and save yourself this whole process later.
