The Ultimate Guide on How to Remove Blood Stains

Blood stains can be a nightmare to deal with, especially if you’re unsure of the best way to tackle them. Whether it’s a small spot on your favorite shirt or a larger spill on your mattress, acting quickly and using the right techniques can make a world of difference. In this guide, we’ll walk you through step-by-step methods to effectively remove blood stains from various surfaces.

Understanding Blood Stains

Blood stains are protein-based stains, which means they require special treatment. The key to removing blood stains is to act fast and avoid using hot water, as heat can set the stain, making it much harder to remove.

Step-by-Step Methods to Remove Blood Stains

1. Removing Fresh Blood Stains from Fabric

Materials Needed:

– Cold water

– Liquid detergent

– Hydrogen peroxide (for stubborn stains)

– Baking soda


1. Rinse with Cold Water: Start by rinsing the stained fabric with cold water. Hold the fabric under running water to flush out as much of the blood as possible.

2. Apply Detergent: Gently rub a small amount of liquid detergent into the stain. Use your fingers to work the detergent into the fabric.

3. Soak: Soak the fabric in cold water for about 30 minutes. For tougher stains, you can add a tablespoon of baking soda to the water to enhance the cleaning process.

4. Rinse and Check: Rinse the fabric thoroughly with cold water and check the stain. If it’s still visible, apply a few drops of hydrogen peroxide directly onto the stain, let it sit for a few minutes, and then rinse again.

5. Launder: Wash the fabric as usual, but avoid using hot water until the stain is completely gone.

2. Removing Dried Blood Stains from Fabric

Materials Needed:

– Cold water

– Salt

– Dish soap

– Ammonia (for persistent stains)


1. Soak in Salt Water: Dissolve a tablespoon of salt in two cups of cold water. Soak the stained fabric in this solution for a couple of hours to loosen the dried blood.

2. Create a Paste: Mix a small amount of salt with cold water to create a paste. Apply this paste to the stain and gently rub it in.

3. Rinse and Apply Dish Soap: Rinse the fabric with cold water and apply a small amount of dish soap. Work the soap into the stain and rinse again.

4. Use Ammonia for Stubborn Stains: If the stain persists, mix one part ammonia with two parts water. Dab this mixture onto the stain with a clean cloth, then rinse thoroughly.

5. Launder: Wash the fabric as usual, ensuring the stain is fully removed before using hot water.

3. Removing Blood Stains from Upholstery and Carpets

Materials Needed:

– Cold water

– Dish soap

– Hydrogen peroxide (for stubborn stains)

– Clean cloths


1. Blot with Cold Water: Use a clean cloth to blot the stain with cold water. Avoid rubbing, as this can spread the stain.

2. Apply Dish Soap Solution: Mix a teaspoon of dish soap with two cups of cold water. Apply this solution to the stain using a clean cloth, and gently blot.

3. Rinse and Blot Dry: Dampen another cloth with cold water and blot the area to remove the soap solution. Continue blotting until the area is dry.

4. Hydrogen Peroxide for Stubborn Stains: For persistent stains, apply a small amount of hydrogen peroxide to the area. Let it sit for a few minutes, then blot with a clean, damp cloth.

5. Dry: Blot the area with a dry cloth to remove excess moisture and allow it to air dry completely.

Tips for Preventing Blood Stains

– Act Quickly: The faster you treat a blood stain, the easier it will be to remove.

– Avoid Heat: Always use cold water when treating blood stains to prevent setting the stain.

– Test First: If using hydrogen peroxide or ammonia, test on a small, hidden area first to ensure it doesn’t damage the fabric or material.
