How to Remove Blood Stains from a Mattress
Kids bring joy—and sometimes unexpected messes. From late-night nosebleeds to surprise scrapes or period leaks, blood stains on a mattress can catch any parent off guard. These stubborn marks might look like the end of a good night’s sleep, but don’t worry—there’s a way to fix it.
You don’t need fancy tools or harsh chemicals to bring your child’s mattress back to life. With a few simple steps and household items, you can lift even dried blood stains and keep your home feeling fresh and clean. Let’s walk through the quickest, most effective methods every caregiver should know.
Why Blood Stains Are Tough to Remove
What Makes Blood Stains Hard to Lift
Blood stains are hard to clean because blood is full of proteins and iron. When it dries, the proteins harden and cling to the fabric, locking the stain in place. The iron can also react with air, making the spot darker and harder to remove. This is why dried blood is much tougher to clean than fresh stains.
The deep red color of blood also stands out on most mattress fabrics, especially lighter ones. That’s why stains can look so obvious and messy. Acting fast is important—cleaning the stain while it’s still fresh gives you a much better chance of getting it out completely.
Cleaning Menstrual Blood Stains
Period blood, or menstrual blood, isn’t always harder to clean than other types, but it can be. That’s because it may also contain mucus or tissue, which can make the stain spread or stick more than regular blood. These extra components can complicate the cleaning process just a bit.
The most important step is to use cold water, not warm. Hot water causes the proteins in blood to set, making the stain worse. By cleaning quickly and using the right tools, you can remove both regular and menstrual blood stains without much trouble.
Materials Needed for Cleaning
Basic Tools for Cleaning Blood Stains
- Clean white cloths or paper towels
These are needed to blot and soak up as much blood as possible without spreading it. - Cold water
Cold water helps lift blood from fabric. Hot water can set the stain, so it should be avoided. - Mild dish soap or gentle laundry detergent
A small amount mixed with water helps break up stains. - Spray bottle
This can help evenly apply water or cleaning solutions to the area. - Baking soda
This is useful for absorbing moisture and odors from the mattress.
Extra Supplies for Stubborn or Set-In Stains
- Hydrogen peroxide (3%)
This is helpful for breaking down older or stubborn blood marks. It should be used carefully and tested on a small spot first to avoid damaging the fabric. - Enzyme-based cleaner
These cleaners are made to break down protein stains like blood. They can be found in the cleaning aisle and are often labeled as safe for upholstery. - Vacuum cleaner
A vacuum can be used after baking soda dries to remove any leftover powder from the mattress. - Meat tenderizer
Unscented, unseasoned meat tenderizer can help break down tough protein stains when mixed with water to make a paste.
The basic tools are usually enough for fresh stains. For dried or tough spots, the extra supplies can help make the cleanup more effective.
How to Remove Blood Stains (Step-by-Step)
Step 1: Get the Mattress Ready
Start by taking off all sheets, mattress covers, and bedding. Wash them separately. Removing extra layers makes it easier to focus on the stained area. Be sure the stain is clearly visible and easy to reach.
Step 2: Dab Fresh Blood Spots
Use a clean white cloth or paper towel to gently blot the blood. Press lightly to soak up as much as possible. Avoid rubbing, as it can push the stain deeper into the fabric and make it spread.
Step 3: Use Cold Water
After blotting, dip a clean cloth in cold water and gently dab the stained area. Cold water helps lift the blood from the fabric before it dries. Work in small circles to avoid spreading the stain, and use a dry towel to blot away any excess moisture.
Step 4: Apply a Gentle Stain Remover
If water isn’t enough, apply a small amount of mild soap, diluted hydrogen peroxide, or a baking soda paste. Use a cloth to place the cleaner directly on the stain. Let it sit for a few minutes so it can break down the blood before moving on.
Step 5: Gently Scrub the Area
With a soft brush or cloth, gently scrub in small circles. Don’t press too hard—this can damage the fabric. For tough stains, you may need to repeat this step until the mark fades.
Step 6: Remove Leftover Cleaner
Wipe away any remaining cleaner with a cloth dampened in water. Then blot the area with a dry towel to soak up leftover moisture. Let the mattress air dry completely before putting the bedding back on.
Effective Ways to Clean Blood Stains
Hydrogen Peroxide
Hydrogen peroxide is a helpful household cleaner for blood stains, especially when other methods fall short. Use 3% hydrogen peroxide and apply a small amount directly to the spot. You might notice fizzing, which helps break down the stain. Let it sit for about five minutes, then blot with a dry cloth to remove the stain and leftover liquid. If needed, repeat the process. Keep the room well-ventilated, and avoid soaking the mattress to prevent moisture buildup.
Ready-Made Stain Removers
Store-bought stain removers are a popular choice for cleaning blood from mattresses. These products are easy to find and usually come with directions for different fabric types.
Before applying, test the product on a small hidden area to make sure it won’t damage the material. Some work better when left on the stain for a few minutes before blotting with a clean cloth. Always check the label to ensure it’s safe for your mattress.
Common Cleaning Mistakes to Avoid
As already mentioned, using hot water can cause blood stains to set, making them harder to remove. Scrubbing the stain too harshly can also push it deeper into the mattress or spread it across a wider area.
Another common mistake is using too much cleaner or water, which can soak the mattress and lead to mold. To prevent these issues, gently blot the stain, use only cold water or recommended cleaners, and make sure the mattress is fully dry before replacing the bedding.
Tips for Removing Dried Blood Stains
Early Steps to Loosen Dried Blood
To start, gently scrape off any dried blood from the mattress surface using a dull knife or the edge of a spoon. Lightly brushing away these flakes helps shrink the stain and makes the next steps more effective. Be careful not to rub too hard, as this can push the stain deeper into the fabric.
Soaking Solutions for Tough Stains
For more stubborn stains, mix cold water with a small amount of mild dish soap. Soak a clean cloth in the solution and press it gently onto the stain. Let it sit for 10–15 minutes. If the spot remains, try a bit of hydrogen peroxide—just make sure to test it on a hidden area first to avoid bleaching. You can also apply a baking soda paste, let it dry, then vacuum it up to help lift the stain.
Extra Steps for Mattress Blood Stain Removal
For deep cleaning, repeating the use of cold water and a clean cloth can slowly lighten the stain without spreading it. After cleaning, make sure the mattress dries completely before putting bedding back on to prevent mold or mildew growth. Keep the area clean and uncovered while it dries to avoid new stains or dust.
How to Dry and Freshen Your Mattress
Best Ways to Dry Your Mattress
After cleaning a blood stain, it’s important to let the mattress dry completely. This helps prevent mold and mildew from forming. Begin by pressing a clean towel onto the damp area to soak up as much moisture as you can. Then, use a fan or open windows to improve airflow and speed up drying.
If possible, place the mattress outside in the sun. Sunlight not only helps dry the fabric but also works to reduce odors. Always make sure the mattress is fully dry before putting the sheets back on to keep it clean and comfortable.
Simple Steps for Mattress Freshening
Even after cleaning, some odors may linger. To remove them, sprinkle a thin layer of baking soda over the cleaned area. Let it sit for a few hours, then vacuum it off thoroughly.
For added freshness, you can mix a few drops of essential oils like lavender or tea tree with the baking soda before applying. Lightly spraying a fabric-safe deodorizer also works—just be careful not to soak the mattress. To keep it smelling fresh over time, air out the room regularly and use a mattress protector.
When to Call a Professional Cleaner
Most fresh or small blood stains can be cleaned at home. But in some cases, it’s best to call a professional. If the stain is large, old, or deep—and doesn’t fade after a few tries—a professional cleaner has stronger tools and products that can help.
It’s also smart to get expert help if the stain spreads over a big area, has soaked deep into the mattress, or smells bad. Professionals know how to deal with stubborn stains and can spot hidden damage. If your mattress is made of delicate or expensive material, calling in a pro can prevent accidental damage.
Blood stains may look intimidating, but with the right tools and steps, you can clean your mattress and keep it fresh. Act fast, use the right tools, and you’ll save yourself time, stress—and possibly a new mattress.
