It’s time to get that concrete looking pristine again ๐Ÿ‘‡

Materials you will need:

  • Cold water
  • Baking soda
  • Hydrogen peroxide or white vinegar (we prefer cleaning vinegar vs. distilled)
  • Stiff-bristled brush or scrub brush
  • Protective rubber gloves (always wear these before coming into contact with blood)
  • Absorbent materials (paper towels, cloth, or absorbent powder. We favor paper towels)

How to Clean Fresh Blood Stains From Concrete With Eco-Friendly Chemicals

how to clean Fresh Blood From Concrete
Attack fresh blood stains quickly
If the blood is fresh, start by blotting the area with absorbent materials like paper towels or an old throw-away cloth to soak up as much blood as possible. Avoid rubbing, as it may spread the stain. The trick here is to minimize the time the blood has to soak into the concrete.
Rinse the stained area with cold water as soon as possible
Use a hose or a bucket of cold water to thoroughly rinse the concrete surface and further dilute the blood.
Apply baking soda paste
Make a paste by mixing baking soda with a small amount of cold water. Apply the paste directly onto the stained area. Baking soda can help absorb and lift the blood stain. The paste should be thick – similar to the consistency used when we cleaned stinky slides.
Gentle scrubbing
Use a stiff-bristled brush or scrub brush to gently scrub the baking soda paste into the stain. Work in circular motions to help lift the blood from the concrete surface.
Apply hydrogen peroxide / white cleaning vinegar
For stubborn or dried blood stains, you can apply hydrogen peroxide or white cleaning vinegar directly to the affected area. Let it sit for a few minutes to help break down the stain. We opted for 6% concentrate.
Scrub again
After applying the natural cleaner, gently scrub the stained area with the brush to further loosen the blood stain.
Rinse and repeat
Rinse the concrete thoroughly with cold water. Check the stain and repeat the process if necessary, especially for persistent stains.
Leave to dry
Allow the cleaned area to air dry completely.

FAQs

Can I use warm water instead of cold water for rinsing the stained area?

While cold water is recommended, warm water can also be used. However, cold water is generally preferred as it helps prevent the blood from setting into the concrete

Can I substitute other cleaning agents for hydrogen peroxide or white cleaning vinegar?

While hydrogen peroxide and white cleaning vinegar are effective, you can experiment with mild dish soap or an enzyme-based cleaner. Always test a small area first to ensure compatibility and effectiveness.

How can I prevent future blood stains on concrete surfaces?

To prevent future blood stains, address spills promptly, and consider applying a concrete sealer to create a protective barrier. Regular cleaning and maintenance can also help minimize the risk of stubborn stains.


What About Dried Blood Stains?

Cleaning dried blood from concrete can be a little bit trickier as the blood has had time to set into the porous surface. You will need a stronger brush and a bit more elbow grease!

Materials you will need:

  • Protective gloves
  • Cold Water
  • Baking soda or hydrogen peroxide
  • Dish soap or liquid detergent (we opt for natural, eco-friendly detergent of course!)
  • Scrub brush or wire brush (tougher bristles needed vs. when cleaning fresh blood stains)
  • White Cleaning Vinegar (optional)
  • Safety goggles (if using hydrogen peroxide)
  1. Safety First: Put on protective gloves and, if using hydrogen peroxide, wear safety goggles to protect your eyes.
  2. Soak and Blot: Dampen the bloodstained area with water. Using a cloth, blot and absorb as much dried blood as possible without spreading it further. Avoid scrubbing at this stage to prevent the stain from setting deeper.
  3. Baking Soda or Hydrogen Peroxide: For small stains, make a paste of baking soda and water, applying it directly to the stain. Let it sit for a few minutes to lift the blood. Alternatively, if using hydrogen peroxide, pour it directly on the stain and let it sit for a few minutes to foam and lift the dried blood. Be cautious with hydrogen peroxide as it may cause discoloration on some surfaces.
  4. Scrubbing: Use a scrub brush or wire brush to gently scrub the stained area. Start with circular motions, gradually increasing pressure if needed to lift the stain. For tougher stains, add a small amount of dish soap or liquid detergent to the brush.
  5. Rinse and Repeat: Rinse the area thoroughly with water. Repeat the process if needed, especially for older or more stubborn stains. For an added touch, consider applying vinegar to the area and letting it sit for a few minutes before rinsing again.
  6. Dry the Area: Pat the cleaned area dry with a cloth or allow it to air dry completely.

Always test any cleaning solution on a small, inconspicuous area first to ensure it doesn’t cause damage or discoloration to the concrete.
