- 1). Wipe blood stains up immediately whenever possible. Use a clean, damp sponge to blot the blood from the floor. If the wood is sealed, you have a good chance of avoiding a stain this way. The longer the blood is in contact with the floor, the more likely it is to leave a stain.
- 2). Apply straight ammonia to a clean rag then wipe the floor to kill germs once the blood is removed. The room must be well-ventilated during this step, and rubber gloves and eye protection are recommended. After a few minutes, wipe the floor with a damp rag to remove the ammonia.
- 3). Use a damp cotton swab to soak up blood that has seeped into cracks or joints. You may need to repeat this process several times to remove a larger amount of blood. Dip a clean swab in ammonia and dab it at joints or cracks to kill any germs left behind.
- 4). Clean dried blood stains with a piece of 000 steel wool. This very fine steel wool may be just enough to remove dried blood without damaging the floor. Scrape very lightly at the stain with the steel wool. You may be able to do this while leaving the floor finish intact. Wipe the floor with a damp sponge, then dry it. Apply a bit of wood flooring wax to blend this area into the rest of the surface.
- 5). Tackle stubborn stains with bleach. Dip a clean cloth in straight bleach, then place it on the blood stain. Let it sit like this for an hour, then remove the rag. Clean the area with a damp sponge, then dry it. This will likely affect your floor finish, so try using a small artist's brush to paint matching stain onto the area. Rub floor wax into the wood once the stain is dried to help blend this section in with the surrounding wood.
