Step-by-Step Instructions
💡 Pro Tips:
Removing Fresh Blood Stains
The faster you act, the easier it will be.
Rinse immediately from the reverse side under cold running water.
Soak in cold water for 30 minutes.
Apply gall soap or enzyme-based laundry detergent directly onto the stain, let it sit for 10 minutes.
Wash in the washing machine at a maximum of 30 °C.
Important: Do not rub, dab instead. Rubbing enlarges the stain and damages the fibers.
Removing Dried Blood Stains
Dried blood requires more time and stronger remedies, but it is resolvable.
Method 1 — Salt Solution: Dissolve 2 tbsp of salt in 1 liter of cold water, soak the stain for several hours, rinse out. Repeat if necessary.
Method 2 — Baking Soda Paste: Mix baking soda with cold water to form a paste, apply to the stain, let it sit overnight, rinse off. Especially good for light-colored textiles.
Method 3 — Aspirin: Dissolve 2–3 aspirin tablets in 1 liter of cold water, soak the stain for one hour, gently work it in, rinse out. Effective for older stains on white fabric.
Method 4 — Gall Soap: Rub directly onto the moistened stain, let it sit for 15 minutes, rinse out with cold water. The most reliable all-rounder for protein-based stains.
Method 5 — Hydrogen Peroxide (3%): Only for white textiles, apply with a cotton ball, let it sit briefly, rinse thoroughly. Test on an inconspicuous area first.
Removing Washed Blood Stains
If the stain has already gone through the washing machine, heat has set it, but giving up is not worth it.
Glycerin: Mix 1:1 with cold water, apply, let it sit for an hour, rinse out, and wash normally.
Vinegar Water: Mix white vinegar and water in a 1:3 ratio, dab onto the stain, let it sit for 20 minutes, rinse thoroughly.
For particularly stubborn cases, combine methods and repeat the treatment multiple times.
Removing Blood Stains from a Mattress
Mattresses cannot be washed, so proceed spot by spot:
Carefully dab away excess blood with a cold cloth.
Apply salt solution (2 tbsp of salt to 250 ml of water) with a sponge, let it sit for 20 minutes, dab off.
Apply baking soda paste, let it dry, vacuum off.
Allow the mattress to air dry completely before using it again.
Removing Blood Stains from a Carpet Here too, the rule is: never scrub, always dab.
Dab fresh blood immediately with cold water and a clean cloth.
Apply salt solution or baking soda paste, let it sit.
Dabbed, never rubbed, until the stain is gone.
Rinse with clear cold water, allow to dry well.

Frequently Asked Questions About Removing Blood Stains
Hot water causes the protein components in the blood to coagulate and permanently sets the stain into the fibers. This makes removal significantly more difficult or even impossible. Instead, always use cold water to avoid setting the proteins and to allow the stain to be dissolved more easily.
With delicate materials such as silk or wool, you should proceed with extra care. First, soak the stain in cold water and then use mild cleaning agents like diluted vinegar or special delicate detergents. Gently dab the stain instead of rubbing it, and let the garment dry flat to prevent reshaping.
Bleach can be effective on white, chlorine-resistant textiles, but it should be used with caution. Always dilute the bleach according to the manufacturer’s instructions and test it on an inconspicuous area first. For colored or delicate fabrics, you should avoid bleach and use gentler alternatives instead, such as lemon juice or enzymatic stain removers.
If a blood stain is still visible after washing, try using a combination of methods. Soak the stain in cold water again and then treat it with a mixture of hydrogen peroxide and dish soap. Let this sit, rinse thoroughly, and wash the garment again. For stubborn stains, repeated treatment with enzymatic stain removers or professional dry cleaning can also help.
To remove blood stains from mattresses without getting them too wet, use a paste made of baking soda and cold water. Apply it to the stain, let it dry completely, and vacuum off the residue. Alternatively, you can carefully dab on a solution of salt and cold water, then wipe it down with a clean, damp cloth. Use as little liquid as possible and allow the mattress to air dry thoroughly afterward.
Yes, even if washed blood stains already seem set in the fabric, they can often be dissolved using gall soap, baking soda, or special enzyme cleaners. It is important to soak the stain in cold water again and under no circumstances treat it with heat, otherwise the protein will permanently crust over.
For carpets, cold mineral water or a paste made of baking soda and water helps. Carefully dab the stain from the outside in to avoid rubbing it further into the fibers.
Dried stains should first be soaked in cold salt water. After that, household remedies like citric acid, aspirin tablets (dissolved in water), or classic gall soap help.
