Blood on Wool — How to Get It Out
Blood on wool needs cold water and enzyme treatment to lift the protein stain without felting or setting it. Hot water will cook the blood into the fiber and shrink wool, so every rinse must stay cold. Work gently—wool is fragile when wet and will felt if you scrub or wring it.

Watch out
Don'tNever use hot or even warm water on blood stains in wool. Heat will both set the stain permanently and cause wool to shrink and felt.
WarningDo not wring, twist, or scrub wet wool. The fibers are weak when wet and will mat together into felt if handled roughly.
TipTest enzyme soap on an inside seam first if the wool is dyed a dark or bright color, as some dyes can bleed.
Do this
Blot fresh blood immediately
Press a clean dry cloth onto the stain to lift as much blood as possible. Do not rub—blotting keeps the stain from spreading deeper into the wool fibers.
If the blood is still wet, blot from the outside edge toward the center to avoid enlarging the stain.
Rinse with cold water
Hold the stained area under cold running water from the coldest tap setting (under 70 °F), letting the water flow through the back of the fabric. Keep rinsing until the water runs clear or the stain lightens noticeably.
Apply enzyme stain soap
Dampen the stain again with cold water, then work about 1 tsp of enzyme stain soap gently into the fabric with your fingertips. Let it sit for 10 minutes so the enzymes can break down the protein.
Rinse and check
Rinse thoroughly with cold water until no soap remains. Check the stain—if a shadow lingers, repeat the enzyme soap step once more.
Lay flat to dry
Roll the wool in a clean towel to press out excess water without wringing. Lay the garment flat on a dry towel away from direct heat or sunlight and reshape it gently while damp.
Common questions
Can I use hydrogen peroxide on blood stains in wool?+
Hydrogen peroxide can bleach wool and weaken the fiber, especially on dark or colored yarn. Stick to cold water and enzyme soap, which are safe and effective for protein stains on wool.
What if the blood stain is old and dried?+
Soak the stained area in cold water for 30 minutes to rehydrate the blood, then apply enzyme soap and let it work for 15–20 minutes. You may need to repeat the treatment twice. Dried blood is harder to lift, but enzymes will still break it down if you give them time.
Can I machine-wash wool after treating a blood stain?+
Only if the care label says machine-washable and you use a wool or delicate cycle with cold water. Most wool should be hand-washed or laid flat to dry to prevent shrinking and felting.
Why does the stain look worse after it dries?+
Blood can leave a faint brown shadow even after the red color is gone. Treat the area again with enzyme soap while the wool is still damp. Once the stain dries completely, it becomes much harder to remove.

BloodCarpet
Blood on Carpet — How to Get It Out
Blood stains on carpet respond best to cold water and enzyme treatment, but you must work carefully to avoid pushing the stain deeper into the pile. Fresh blood lifts more easily than dried, so start as soon as you notice the spot. Never use hot water — it will cook the protein and set the stain permanently.
BloodCotton
Blood on Cotton — How to Get It Out
Blood stains come out of cotton easily if you act quickly and use cold water—hot water will set the protein permanently. Cotton is durable and can handle scrubbing, soaking, and repeated treatment, so even dried blood usually responds well to enzyme soap and patience.
BloodCotton
Blood on Cotton Shirt — How to Get It Out
Blood stains on a cotton shirt come out cleanly if you act quickly and keep the water cold—hot water will cook the protein and lock the stain into the fibers. Cotton is durable enough to handle enzyme soap, peroxide, and machine washing, but you must treat the stain before it dries. Follow these steps to lift fresh or dried blood without damaging the fabric.
BloodDenim
Blood on Denim — How to Get It Out
Blood stains come out of denim easily if you act fast and keep the water cold. Hot water cooks the protein in blood and locks it into the fabric, so always start with the coldest tap setting. Denim's tight weave and sturdy cotton fibers can handle scrubbing, which makes this job simpler than on delicate fabrics.
BloodLinen
Blood on Linen — How to Get It Out
Blood stains come out of linen easily if you act fast and keep the water cold—hot water will cook the protein and lock the stain into the fibers permanently. Linen is durable and can handle vigorous treatment, but you must start with cold water and work the stain from the back so you push it out rather than deeper into the weave.

GrassWool
Grass Stain on Wool — How to Get It Out
Grass stains on wool come out with cold water and enzyme stain soap, but you must work gently to avoid felting the fibers. Chlorophyll from grass is a stubborn pigment that binds to protein fibers like wool, so patience and the right technique matter more than scrubbing hard.
