Remove blood from light-colored carpet by brushing away dried blood, applying a dish detergent solution, blotting the stain, applying an ammonia solution, and blotting again. Continue wetting and blotting until the stain disappears.
- Brush away the dried blood
Use a stiff, dry brush to loosen and remove any dried blood from the surface of the carpet fibers. Do not add liquid at this time, as it is likely to dissolve the blood and move it deeper into the fibers. Vacuum to remove any dried blood you have loosened.
- Wet the stain with dish detergent
Mix a squirt of liquid dish soap in a pint of cold water. Apply the solution to the carpet using a white rag. Use a clean towel to blot the moisture from the rug. Wet and blot the stain repeatedly until you are unable to remove any more of the bloodstain from the carpet.
- Clean the area with ammonia
Mix a tablespoon of ammonia in 1/2 cup of cold water. Use a clean sponge to apply the ammonia to the carpet. Dry the rug by blotting with a clean, dry towel. Repeat this process if necessary. Once the blood is gone, apply plain water, and blot the area dry to remove any detergent or ammonia residue.
