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.

    Wear clothing that will protect your skin from getting in contact with the chemicals. [1]

    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]

    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]

    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]
