A number of incidents can lead to blood stains on the walls. These stains are not very pleasant to look at, and you have to spend a lot of effort to wash them off. However, with the right preparation and a couple of detergents, the walls will be clean again.

Steps

Method 1 of 3: Removing blood from any surface

1. 1 Start cleaning the blood stains as soon as possible. Blood stains eventually penetrate deeper layers of walls, making them more difficult to clean. Try to remove blood stains as they appear.
2. 2 Wipe off as much blood as possible before cleaning the walls. If the blood hasn't dried yet, blot it with a rag or paper towel. If the blood has dried, try scrubbing it off the walls gently with a plastic spatula or similar. Be very careful not to scratch the surface of the wall.
   • Dampen old stains gently with water.
3. 3 Start cleaning with the mildest product possible. Use a soft cloth or paper towels instead of an abrasive sponge. First, try rinsing the stain off with water. If all else fails, use a cleaner or special stain remover.
   • Try wiping off the blood with saliva.
   • Before cleaning the entire surface, test the effect of the cleaning agent on an inconspicuous area.
4. 4 Take special precautions if blood may contain pathogens. Put on gloves and use a disinfectant. Take extra care when cleaning up blood stains or spills of unknown origin. Although the likelihood of catching a disease while cleaning blood stains (especially old ones) is extremely small, it is still better to play it safe.
   • Use freshly diluted bleach or specialty disinfectant that is labeled to kill bloodborne pathogens such as HIV, hepatitis B and C.
   • If blood is spilled in a public facility, such as a school, prison, or hospital, follow that facility's regulations regarding the disposal of bodily fluids.

Method 2 of 3: Removing Blood Stains from Painted and Papered Walls

1. 1 Be very careful with the wallpaper. Although vinyl wallpaper is easier to clean, it will still start to peel off the walls if you oversaturate it or rub it too hard. If possible, try not to clean at the seam joints.
2. 2 Prepare a solution by mixing a liter of room temperature water and half a teaspoon (2.5 ml) of dishwashing liquid. Add a tablespoon (15 ml) of ammonia to make the solution stronger.
3. 3 Take an unnecessary terrycloth towel, rag, or soft sponge and dip it in the soapy water. Squeeze out excess water to keep the cloth from getting wet. Then gently wipe the stain. If necessary, dip the cloth back into the solution and wring it out.
4. 4 Make a paste with baking soda and water. Rub the paste gently into the stain. Rinse off the paste with clean water and wipe dry with a soft cloth.
5. 5 Spray the stain with peroxide. Leave the solution on for a while, wiping up any spills. Wipe the stain very gently and then wash it off with plain water.
6. 6 Use an enzyme. This product contains enzymes that are designed to digest food and other body fluids that contain protein. Follow the directions on the bottle. Take precautions and test on an inconspicuous area of ​​the wall before using the product.
7. 7 Wipe the stain dry with a clean cloth and wait until it is completely dry. Do not leave any cleaner on the wall. Even if this attempt fails, be sure to dry the stain thoroughly so as not to ruin the paint or wallpaper.
8. 8 Repaint the wall. If you are having trouble removing a blood stain from a painted wall, try painting over it. If you've painted a wall recently, paint over only the stained area. If a long time has passed, you will have to repaint the entire wall. Remember to apply a primer to the stain first. Some primers are specifically designed to cover stains. Read the bottle label to find the most suitable primer.
9. 9 Cover the stained wallpaper with pieces of wallpaper. Cut a piece of wallpaper large enough to cover the stain and glue it to the wall. In this case, see that the picture matches.Cut through both layers of paper with a utility knife and a ruler. Peel off the layer and set it aside, then carefully remove the stained paper underneath and the wallpaper particles. Insert a new piece according to the instructions. Align the patch to match the picture and smooth it out with a damp sponge.

Method 3 of 3: Cleaning blood stains from tiles

1. 1 Use a non-abrasive household degreaser. Use a sponge to wipe the stain. A regular sponge is soft enough not to scratch the tiles, but it's better to play it safe and check its effect on an inconspicuous part of the wall. When done, wash off all traces of degreaser with clean water.
   • Make your own tile and mortar cleaner by mixing 1/2 cup (120 g) baking soda, 1/3 cup (80 ml) ammonia, ¼ cup (60 ml) white vinegar, and seven cups (1.7 L) water. Mix it all in a spray bottle, stir well and spray on the stained area. Then wipe it off and rinse with water.
2. 2 Apply hydrogen peroxide, diluted bleach, or white vinegar to the stained seam. Scrub it gently with a sponge. Rinse the joint with clean water and then remove any remaining cleaning agent.
3. 3 Use a commercially available tile cleaner. Follow the directions on the bottle carefully, as these products can be toxic.
4. 4 Cover the stain with a paper towel. Blot a towel with dish soap and a little water. Leave the mixture on the stain for half an hour, then rinse the stain and wipe it dry.

Warnings

• Never mix ammonia with chlorine bleach, as the mixture produces poisonous gas.
