Knowing how to get blood out of clothes is a practical life skill that can save your favorite outfits from permanent damage. Blood stains are protein-based, which means they behave differently from common food or dirt stains. If treated incorrectly—especially with heat—they can set deeply into fabric fibers and become extremely difficult to remove.
This detailed guide explains how to get blood out of clothes quickly, whether the stain is fresh, dried, or even already washed and set. Drawing from textile science, professional laundry practices, and real-world experience, this article walks you through safe, fabric-friendly methods using common household items like hydrogen peroxide, baking soda, and salt.
By understanding why blood stains bond to fabric and how different cleaning agents interact with those proteins, you can remove stains effectively without damaging your clothing.
How to Get Blood Out of Clothes Quickly (Fresh Stains)
Fresh blood stains are the easiest to remove because the proteins have not yet bonded tightly with the fabric fibers. Acting fast significantly improves success rates.
● Use Cold Water Immediately
Cold water prevents blood proteins from coagulating. Running the stained area under cold water from the back side pushes blood out rather than deeper into the fibers, which is critical for quick removal.
● Avoid Hot Water Completely
Heat causes blood proteins to bind permanently to fabric. Even warm water can set a stain, making it much harder to remove later.
● Blot, Don’t Rub
Blotting lifts blood out gently without spreading it. Rubbing forces blood deeper into the weave, enlarging the stain and weakening fibers.
● Soak Before Drying
Allowing fabric to air-dry with blood still present can set the stain. Always ensure the stain is fully gone before drying.
● Check Fabric Type First
Cotton, polyester, and blends respond well to cold-water flushing, while delicate fabrics require gentler handling.
● Repeat If Necessary
Fresh blood may not lift completely on the first attempt. Repeating the cold-water process is safe and effective.

How to Get Blood Out of Clothes with Hydrogen Peroxide
Hydrogen peroxide is one of the most effective treatments for blood stains because it breaks down proteins through oxidation.
● Understand How Peroxide Works
Hydrogen peroxide releases oxygen bubbles that lift blood particles from fabric fibers, making it especially effective on light-colored clothing.
● Test for Colorfastness
Peroxide can bleach dyed fabrics. Always test on a hidden seam before applying it to visible areas.
● Apply Directly to the Stain
Pour a small amount directly onto the stain and let it bubble. This reaction indicates the stain is breaking down.
● Blot After Bubbling Stops
Once bubbling subsides, blot with a clean cloth to lift loosened blood from the fabric.
● Rinse with Cold Water
Rinsing removes residue and prevents chemical damage to fibers.
● Repeat Carefully if Needed
Multiple light applications are safer than one heavy dose, especially on delicate fabrics.

How to Get Blood Out of Clothes with Peroxide (Fabric-Specific Tips)
Different fabrics respond differently to hydrogen peroxide, making fabric awareness essential.
● Cotton and Polyester Respond Best
These fabrics tolerate peroxide well and show fast stain removal results.
● Denim Requires Caution
Peroxide can lighten denim unevenly, so diluted solutions are safer.
● Silk and Wool Are High Risk
Natural protein fibers react poorly to peroxide and should be treated professionally.
● Synthetic Blends Need Spot Testing
Blended fabrics may react unpredictably due to mixed fiber content.
● Avoid Excess Saturation
Too much peroxide weakens fibers over time and can leave marks.
● Neutralize After Treatment
A cold-water rinse fully stops the oxidation process, preserving fabric integrity.

How to Get Blood Out of Clothes with Baking Soda
Baking soda is a gentle yet effective option for lifting blood stains, especially for sensitive fabrics.
● Create a Thick Paste
Mix baking soda with cold water to form a paste that clings to fabric without spreading.
● Apply Evenly Over the Stain
Cover the stain completely to ensure even absorption of blood particles.
● Let It Dry Naturally
As the paste dries, it pulls blood out of the fibers through absorption.
● Brush Off Residue Gently
Once dry, brush off the paste without scrubbing to avoid fiber damage.
● Rinse with Cold Water
Cold rinsing removes remaining particles without setting the stain.
● Repeat for Older Stains
Baking soda works gradually and may need multiple applications for darker stains.

How to Get Blood Out of Clothes with Salt
Salt works as a natural absorbent and mild abrasive, especially for fresh stains.
● Dissolve Salt in Cold Water
Saltwater prevents blood from binding to fabric fibers during soaking.
● Soak the Stained Area
Extended soaking allows salt to draw blood out gently.
● Use Fine Salt for Better Absorption
Fine grains penetrate fibers more effectively than coarse salt.
● Avoid Hot Water at All Costs
Heat neutralizes salt’s effectiveness and sets blood stains permanently.
● Rinse Thoroughly After Soaking
Salt residue can stiffen fabric if not rinsed out fully.
● Best for Lightweight Fabrics
Salt is ideal for shirts, underwear, and cotton blends.

How to Get Blood Out of Clothes After Washing
Washed-and-dried blood stains are more challenging but not impossible to remove.
● Identify Heat-Set Stains
Dryer heat locks blood into fibers, requiring stronger treatments.
● Rehydrate the Stain First
Soaking in cold water loosens dried proteins before treatment.
● Use Peroxide or Enzyme Cleaners
Enzymes break protein bonds that normal detergents can’t.
● Avoid Rewashing Before Treatment
Repeated washing without stain removal makes stains worse.
● Air-Dry Between Attempts
Heat will permanently set any remaining stain.
● Know When to Stop
Excessive treatment can damage fabric beyond recovery.

Conclusion
Learning how to get blood out of clothes empowers you to act quickly and confidently when accidents happen. Whether you’re dealing with a fresh stain or a dried, washed one, the right method—cold water, hydrogen peroxide, baking soda, or salt—can restore your clothing safely. By understanding the science behind blood stains and using fabric-appropriate techniques, you can prevent permanent damage and extend the life of your garments.
FAQs
Q: Can hot water ever remove blood stains?
No. Hot water sets blood stains permanently.
Q: What works best on old blood stains?
Hydrogen peroxide or enzyme-based cleaners offer the highest success.
Q: Is hydrogen peroxide safe for colored clothes?
Only after spot testing, as it may bleach fabric.
