Blood stains come out most reliably when treated quickly with cold water, before heat can set them. This shows how to lift fresh and dried blood from fabric using simple household products.
What you'll need
- Cold water
- Bar or liquid soap
- Hydrogen peroxide
- Salt or baking soda
- Clean cloth
Step by step
- Rinse with cold waterHold the stained area under cold running water from the back of the fabric to push the blood out rather than through. Never use hot water, which sets blood.
- Blot, do not rubDab the stain with a clean cloth to lift blood away. Rubbing spreads it and works it deeper into the fibers.
- Apply soap or a pasteWork bar or liquid soap into the stain, or make a paste of salt or baking soda and cold water and let it sit for a few minutes.
- Treat stubborn stains with peroxideFor tougher or dried blood, dab a little hydrogen peroxide on the spot and let it bubble. Test a hidden area first, as it can lighten some fabrics.
- Rinse and repeat if neededRinse with cold water and check the stain. Repeat soaking and treating until the mark is gone before washing.
- Wash and air checkLaunder in cold water, then check before drying. Only put it in the dryer once the stain is fully gone, since heat locks it in.
Handy tips
- Act fast; fresh blood lifts out far more easily than a stain that has dried and set.
- For dried blood, soak in cold water first to rehydrate the stain before treating it.
- Always confirm the stain is gone before drying, because heat can make it permanent.
Heads up
- Hydrogen peroxide can bleach or fade colored and delicate fabrics, so test a hidden spot first.
- Do not use hot water or a hot dryer until the stain is fully removed, as heat sets blood permanently.
FAQ
Why does cold water work better than hot on blood?
Heat cooks the proteins in blood and bonds them to the fabric. Cold water keeps the stain loose so it can be rinsed and lifted out.
How do I get dried blood out of clothes?
Soak the item in cold water to loosen the stain, then treat with soap or hydrogen peroxide. Repeat as needed before washing in cold water.
Is hydrogen peroxide safe on all fabrics?
No. It can lighten colors and harm delicate materials, so always test a hidden area first and use it sparingly.
