This is the best way to clean blood off of shoes. A hospice nurse showed us this blood cleaning hack.
Ingredients
1TBSP% hydrogen peroxide
1cupCold water
1pieceClean cloth or cotton ball
Instructions
Preparation: If the blood is still wet, blot (do not rub) as much of it off with a clean cloth. If the blood has dried, scrape off any excess from the surface.
Spot Test: Apply a small amount of hydrogen peroxide to a less visible area of the shoe to check for color fastness.
Application: Dab a cloth or cotton ball in 3% hydrogen peroxide and gently pat it onto the stain. For textured surfaces like sneakers, you can use a soft brush to lightly apply the hydrogen peroxide.
Rinsing: Blot the area with a clean, damp cloth to remove the hydrogen peroxide and loosened blood. Repeat the application if necessary.
Drying: Let the shoe air dry away from direct sunlight.
