Quick Answer
For fresh blood, blot away excess liquid and rinse the stain from the back with cold running water. Apply a small amount of enzyme-containing liquid laundry detergent or a blood-stain pretreatment that is safe for the fabric, allow the label-approved contact time, and wash according to the garment care label.
For dried blood, soak the garment in cool or lukewarm care-label-safe water with an enzyme product before washing. Air-dry and inspect the fabric before using a dryer because heat can make remaining protein residue considerably harder to remove.
Use disposable gloves when handling blood that is not your own or when skin contact is a concern. Avoid touching your face, wash your hands afterward, and never mix chlorine bleach with ammonia, vinegar, acids, peroxide products, or another cleaner.

Understand the issue
Why Blood Stains Become Harder to Remove
Blood is a protein-based stain containing cells, proteins, salts, and other material that can bind to fabric as it dries. Heat can change the protein structure and make the stain more difficult to release, which is why fresh blood is normally started with cold water rather than hot water.
The correct method depends on the age of the stain, whether the garment has already been washed or dried, and what the fabric can tolerate. Cotton and durable polyester often allow a more thorough pretreatment than wool, silk, acetate, structured garments, or dry-clean-only clothing.
The stain was allowed to dry
As moisture evaporates, blood residue settles more firmly between and around the fibers. A dried stain usually needs soaking and repeated gentle treatment rather than a quick rinse.
Hot water was used too early
High temperature can set protein-based stains. Once the stain has been heated, it may require several treatment cycles and may not disappear completely.
The garment went through a dryer
Dryer heat can make remaining stain residue harder to remove, even when the mark looked faint while the garment was wet.
The stain was rubbed or scrubbed outward
Hard rubbing can spread blood into a wider area, push it deeper into fabric, and roughen delicate fibers.
The wrong cleaner was used
Chlorine bleach, peroxide, enzymes, and stain removers are not safe for every fabric or dye. An unsuitable treatment can lighten color or weaken the material without fully removing the stain.
The stain contains more than blood
Makeup, ointment, body oil, soil, medicine, or another substance may be mixed into the mark and require a second treatment after the protein portion is removed.
Prepare first
What You Will Need
Gather these items before starting.
Cold running water
Fresh blood should normally be flushed with cold water before heat or strong treatment is introduced.
Enzyme-containing liquid laundry detergent
A compatible enzyme detergent can help break down protein-based residue on washable fabrics. Check restrictions for wool, silk, and other protein fibers.
White absorbent cloths or paper towels
Use them to blot excess liquid and monitor stain transfer without adding colored dye to the fabric.
Clean basin or bucket
Useful for soaking a dried stain in clean water and keeping it separate from other laundry.
Disposable or washable protective gloves
Wear gloves when handling someone else’s blood, open cuts, or a heavily contaminated item.
Optional oxygen-based laundry product
A compatible oxygen pretreatment may help with remaining discoloration on washable colorfast fabrics.
Optional 3% hydrogen peroxide
It may lift selected blood stains on suitable white or colorfast fabrics, but it can bleach color and must be patch-tested.
Safety and care
Before You Start
Wear gloves when handling blood that is not your own, avoid shaking the garment, and wash your hands after removing the gloves.
Begin fresh blood treatment with cold water. Do not start with hot water.
Do not tumble-dry, iron, or expose the garment to strong heat until the stain is gone.
Do not use enzyme detergent on wool or silk unless the product specifically says it is safe for those fibers.
Hydrogen peroxide can remove color. Test it on a hidden seam and allow the test area to dry before treating the visible stain.
Never mix chlorine bleach with ammonia, vinegar, acids, hydrogen peroxide, oxygen products, or another cleaner.
Dry-clean-only, structured, antique, valuable, heavily contaminated, or medically sensitive items may require professional handling.
Main method
Step-by-Step Instructions
Follow every step in order for a safer and more reliable result.
Step 1
Protect yourself and inspect the garment
Put on gloves when the blood belongs to another person, when you have broken skin, or when the item is heavily soiled. Keep the garment away from food-preparation areas and avoid shaking it.
Read the care label and identify the fiber, color, stain size, and stain age. Check whether the garment has already been washed, ironed, or tumble-dried.
Helpful Tip
Treat the stain before washing the rest of the load so you can confirm that the treatment is safe and effective.
Step 2
Blot away fresh excess without rubbing
Press a white absorbent cloth against a wet stain to lift excess blood. Move to a clean part of the cloth each time so the stain is not transferred back.
Do not scrub in circles or rub outward. Work gently from the outer edge toward the center when blotting is required.
Step 3
Rinse fresh blood from the back with cold water
Hold the wrong side of the fabric under cold running water so the water pushes the stain back out through the route it entered.
Continue until the water runs substantially clearer. Avoid high pressure on delicate fabric, loose knits, embroidery, or damaged seams.
Step 4
Pretreat the remaining mark
Apply a small amount of enzyme-containing liquid laundry detergent or a blood-stain product that is compatible with the fabric. Spread it across the stained fibers with fingers, a soft cloth, or a very soft brush.
Allow only the contact time stated on the product label. Do not allow concentrated detergent or stain remover to dry on the garment.
Step 5
Soak dried blood before washing
For a dried stain, place the garment in cool or lukewarm care-label-safe water with a compatible enzyme detergent or pretreatment. Ensure the stained section remains submerged.
Check the stain periodically and replace heavily discolored water. A stubborn dried mark may need more than one soak, but delicate or unstable dyes should not be left for an unapproved long soak.
Step 6
Gently work loosened residue from the fibers
After soaking, press the fabric together gently or use a soft brush on durable material. Work from the outer edge toward the center.
Avoid scraping dried blood with a sharp object because it can damage fibers and spread biological material.
Step 7
Wash according to the care label
Wash the garment using the cycle and warmest temperature allowed by its label after the cold-rinse and pretreatment stages are complete.
Use the correct measured detergent dose and avoid overloading the washer. Heavily contaminated items may need to be washed separately.
Step 8
Air-dry and inspect under good light
Remove the garment from the washer and inspect both sides of the stained area while it is damp. Then air-dry it in a suitable place.
A faint stain can become easier to see when fully dry. Do not use a tumble dryer until you are satisfied that the mark has been removed.
Step 9
Repeat treatment for washed or set-in blood
For a stain that has already been washed or dried, repeat the enzyme soak and pretreatment rather than immediately using a stronger chemical.
On compatible white or colorfast fabric, a patch-tested oxygen product or small amount of 3% hydrogen peroxide may help. Rinse thoroughly and stop if the fabric lightens, weakens, or changes texture.
Choose the right method
Instructions by Material or Surface
Use the instructions that match your item.
White cotton and linen
Best for: Sheets, shirts, towels, and durable washable whites
Rinse fresh blood with cold water, pretreat with compatible enzyme detergent, and wash using the care-label-safe cycle.
Remaining discoloration may be treated with a label-approved oxygen product or patch-tested hydrogen peroxide when the fabric and trims allow it.
A white garment may still contain colored stitching, elastic, prints, coatings, or spandex that can react differently.
Colored cotton and denim
Best for: Colorfast shirts, jeans, trousers, and casual clothes
Use cold rinsing and enzyme detergent after testing an inside seam. Treat the visible stain gradually and avoid chlorine bleach.
Dark denim can hide a wet stain, so air-dry and inspect it in natural light.
Peroxide and oxygen products may lighten unstable dye.
Polyester and washable blends
Best for: Uniforms, activewear, and synthetic everyday clothing
Rinse and pretreat promptly because synthetic fibers may hold onto body oils mixed with the blood.
Use a compatible enzyme detergent and avoid high dryer heat until the stain is fully removed.
Wool, silk, and protein-based fibers
Best for: Delicate garments with limited home-washing options
Follow the care label and use a detergent designed for the fiber. Blot and rinse only when the garment instructions allow it.
Avoid ordinary enzyme detergent, aggressive rubbing, peroxide, chlorine bleach, and temperature shock.
Valuable, lined, structured, or dry-clean-only garments should go to a professional cleaner promptly.
Acetate, rayon, and delicate construction
Best for: Garments sensitive to soaking, agitation, or solvent treatment
Use minimal handling and follow the exact label. Do not assume a method safe for cotton is safe for acetate, rayon, lining, adhesive, or decorative trim.
Provide the professional cleaner with information about what caused the stain and which treatments have already been attempted.
More options
Alternative Methods
Use these options only when they suit the material.
Color-safe oxygen pretreatment
Best for: Remaining discoloration on compatible washable fabric
Patch-test the product, follow the dilution and contact-time instructions, and rinse thoroughly before laundering.
Do not combine the oxygen product with chlorine bleach or another stain treatment.
Patch-tested 3% hydrogen peroxide
Best for: Selected white or colorfast washable fabrics
Place a white towel under the stain, apply a small amount, blot the released stain, and rinse thoroughly. Repeat only if the fabric remains unchanged.
Peroxide may bleach colors and should not be treated as universally fabric-safe.
Professional cleaning
Best for: Dry-clean-only clothing, delicate fabrics, large stains, or failed home treatment
Tell the cleaner that the stain is blood, how old it is, and whether heat, detergent, peroxide, bleach, or another product has already been used.
Protect your item
Common Mistakes to Avoid
Starting with hot water.
Rubbing fresh blood across a larger area.
Putting the garment in a dryer before inspection.
Using enzyme detergent on wool or silk without product approval.
Applying peroxide to colored fabric without a hidden-area test.
Pouring chlorine bleach directly onto the stain.
Mixing bleach with peroxide, vinegar, ammonia, acids, or another cleaner.
Shaking heavily contaminated clothing or handling someone else’s blood with bare hands.
Assuming a heat-set stain will disappear after one treatment.

Common questions
Frequently Asked Questions
Should blood stains be washed in hot or cold water?
Start fresh blood with cold water because heat can set protein stains. After pretreatment, wash using the temperature permitted by the garment care label and treatment instructions.
How do I remove dried blood from clothes?
Soak the stain in cool or lukewarm care-label-safe water with a compatible enzyme detergent, gently work the loosened residue, wash, and air-dry. A dried stain may require several treatment cycles.
Can hydrogen peroxide remove blood stains?
A small amount of 3% hydrogen peroxide may lift blood from selected white or colorfast fabrics, but it can bleach dye. Test a hidden area, use it separately from other cleaners, rinse thoroughly, and follow the care label.
Can I remove a blood stain after the clothes were dried?
Sometimes, although dryer heat makes removal harder. Repeat an enzyme soak and pretreatment, air-dry, and inspect. Permanent discoloration may remain after repeated heat exposure.
Can I use bleach on a blood stain?
Only use a bleach product when both the garment label and product directions permit it. Chlorine bleach can damage color, spandex, wool, silk, and some finishes. Never mix it with another cleaner.
Is blood a protein stain?
Yes. That is why cool initial rinsing and compatible enzyme pretreatment are commonly used, while early heat is avoided.
Should I wear gloves when cleaning blood from clothes?
Wear gloves when the blood is not your own, when you have cuts or irritated skin, or when the item is heavily contaminated. Avoid touching your face and wash your hands after removing the gloves.
