Removing blood stains from concrete seems to be a daunting task. Concrete is porous and stain would tend to soak into it on contact. That is why stain removal for concrete is really tough and needs special treatment. For effectively removing blood stains from concrete, the chemical method should be used. This involves the application of water or specific chemicals. The chemicals dissolve the stain so that it can be blotted up from the surface of the concrete. This article shows the steps used in the chemical method.

  3. Do this very carefully and make sure you do not breath any of the peroxide dust nor let it come in contact with your skin. Sodium Peroxide is highly toxic. [3]
  4. There are 2 ways to do this.
    • Sprinkle the layer with mist of water. You can use a spray bottle for this. Remember to do this carefully. Sodium peroxide is toxic.
    • Apply a bandage saturated with water on the layer. [4]
  5. It is very important that you do this thoroughly. If not, the acid used for the blood stain removal can still continue to etch through the concrete if it remains on the surface. [5]

    You can try using a mixture of dish soap and warm water as a starting point. Scrub it well and add a sprinkle of baking soda to lift off the grime and dirt. If the stain is still holding on, pour a little white vinegar over the baking soda and let the bubbling reaction work on the stain for about five minutes. After that, scrub the area again and rinse it with clean water. If tough spots still exist, a second round of application with this mixture should do the trick!

      • Instead of sodium peroxide, you can use hydrogen peroxide or trisodium phosphate instead. But they may not work be as effective as sodium peroxide. If you use hydrogen peroxide, vinegar neutralization is not longer necessary.
