Blood is a messy substance to clean up and can leave stains that are hard to remove no matter how much you scrub. You may know the rules for cleaning blood out of fabric, but when an accident leaves a stain on your hardwood floor or wooden kitchen table, you obviously can't throw those materials into the washing machine. It is possible to remove blood stains from wood and make it look good as new again.
Things You'll Need
Soak up as much of the blood as possible with a paper towel.
Dip a washcloth in cold water and ring it out. It should be wet but not soaked. Too much water can run, taking the blood with it and contaminating other areas of the wood.
Dab at the blood stains with the wet washcloth and gently scrub back and forth. Use a dry washcloth to dab the areas dry after you have scrubbed away as much as you can. Do not let the water sit on the wood or it will stain it.
Dip the washcloth into hydrogen peroxide if the cold water did not remove all of the stain. Repeat the procedure of dabbing and lightly scrubbing the stain with the peroxide. Rinse the cloth and wood with cold water. Use a second washcloth to dry the area.
Repeat this process with bleach on lighter wood. If you have darker wood, only use bleach if it is worth staining the wood to remove the stain. It can leave a lighter spot that is less noticeable on light-colored wood.
Clean the stain up immediately. Always test cleaning products on a small, inconspicuous area first to see if the product removes the finish.
