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.

Watch out
Don'tNever use hot water on blood. Heat cooks the protein into the fibers and makes the stain permanent.
WarningDo not put the garment in the dryer or iron it until the stain is completely invisible. Heat from drying or ironing will set any remaining blood.
TipHydrogen peroxide can bleach dark or brightly colored cotton. Always test on an inside seam or hem before treating a visible area.
Do this
Rinse with cold water immediately
Hold the stained area under cold running water from the coldest tap setting (under 70 °F), letting the stream push blood out through the back of the fabric. Keep rinsing until the water runs clear or the stain stops fading.
Cotton is tough—you can stretch the fabric taut over a bowl and pour cold water through the stain from a height to help flush it out.
Apply enzyme stain soap
Rub about 1 tsp of enzyme stain soap directly into the damp stain, working it in with your fingers or a soft brush. Let it sit for 10 minutes so the enzymes can break down the protein.
Scrub gently and rinse
Use a soft brush or old toothbrush to scrub the soaped area in small circles, then rinse thoroughly with cold water. Check that the stain is completely gone before moving to the next step.
Treat stubborn residue with hydrogen peroxide
If a shadow remains, pour 1 tbsp of hydrogen peroxide 3 % directly onto the stain and let it fizz for 2–3 minutes. Rinse with cold water and repeat if needed.
Peroxide is safe for white and colorfast cotton, but test on a hidden seam first if the fabric is dyed or printed.
Wash in cold water
Once the stain is invisible, wash the garment in the machine on a cold cycle with your regular detergent. Air-dry or tumble-dry only after you confirm the stain is gone—heat will lock in any remaining traces.
Common questions
Can I remove old dried blood from cotton?+
Yes, but it takes longer. Soak the fabric in cold water for 30 minutes to rehydrate the stain, then apply enzyme stain soap and scrub with a brush. Repeat the soap treatment and let it sit for up to an hour if needed before rinsing and washing.
What if I don't have enzyme stain soap?+
Use liquid laundry detergent that lists enzymes or protease on the label—most standard detergents contain them. Rub it into the damp stain and let it sit for 10 minutes before scrubbing and rinsing.
Is it safe to use bleach on white cotton with blood stains?+
Not as a first step. Bleach can react with blood and make the stain harder to remove. Treat with cold water and enzyme soap first, then use oxygen bleach or hydrogen peroxide if a shadow remains.
Why does the stain turn brown after I wash it?+
You used warm or hot water, or the garment went into the dryer before the stain was fully gone. The heat cooked the protein, turning it brown and setting it permanently. Always rinse and treat in cold water, and air-dry until you're certain the stain is invisible.

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.

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.
BloodLinen
Blood on Linen — How to Get It Out
Blood stains on a linen shirt come out cleanly if you act quickly and use cold water—never hot, which sets the protein permanently. Linen is strong and absorbent, so the stain may look dramatic at first, but the fiber responds well to enzyme treatment and patient rinsing. Follow these steps to lift the stain without damaging the weave.

Blueberry Stain on Cotton — How to Get It Out
Blueberry stains on cotton come out reliably if you treat them with cold water and enzyme soap before washing hot.

How to Get Chocolate Out of Cotton
Chocolate stains on cotton respond well to cold water and enzyme treatment because cotton can handle vigorous scrubbing and hot washing once the stain is pretreated. The key is to lift the cocoa butter and sugar without letting heat set the protein and fat before you've broken them down. Cotton's durability means you can be more aggressive than you would with delicate fabrics.
CoffeeCotton
Coffee on cotton — how to get it out
Coffee stains on cotton come out reliably if you rinse them cold first, treat with enzyme soap, and then wash hot. Cotton is tough enough to handle aggressive stain removal, so you can use hot water and scrubbing without worry once the tannins are broken down. Fresh spills lift in minutes; older stains need a soak.

Coffee on Cotton Tablecloth — How to Get It Out
Coffee stains on a cotton tablecloth come out easily if you act quickly, because cotton is durable and can handle both vigorous scrubbing and hot water after pretreatment.
