How to Clean Blood With Bleach

Blood spills are cause for concern and panic.
That is because blood spills are considered a biohazard. There is a risk of obtaining a communicable disease, such as the Hepatitis B virus, from blood. Even just a small amount of blood can splatter and cover a deceptively large area. As the area that the blood has touched has to be decontaminated, diluted bleach is the recommended solution.

Step 1

Put on latex gloves. This is a requirement any time that there is the risk of contamination from blood. Before you put them on, examine them closely for rips or tears. After you put them on, bend your fingers to make sure that they fit and that they won’t rip or tear while you are cleaning up the blood.

Step 2

Protect your skin and eyes. If possible, put on glasses or goggles to protect your eyes. Also, protect your clothes and skin as much as possible. Most people do not have a biohazard suit handy to protect themselves. If possible, wear durable clothing in multiple layers. Cover every bit of skin.

Step 3

Mop up the blood with towels. The number of towels you should use depends on the amount of blood that needs to be cleaned up. Clean up as much as you can. There will still be some blood remaining.

Step 4

Put the blood-soaked towels in a large, sealed plastic bag. Label it as biohazard. Contact your local Hazardous Materials department. Schedule a time for the crew to pick it up.

Step 5

Create the cleaning solution. In a large bucket, combine 10 parts of warm water to 1 part bleach.

Step 6

Mop up the blood. Use a standard mop and the bleach solution and clean up the remainder of the blood. It’s integral that you clean up every single drop of the blood.

Step 7

Disinfect all tools used to clean up the blood. This includes the mop and bucket used. Use a mixture of 10 parts of warm water to 1 part bleach to disinfect them.
