How to Clean Blood from Carpet

It is easiest to remove blood when it is still wet. Dried blood stains are notoriously harder to remove. Also be sure throughout the process to blot the stain, not rub it, as this will only push the stain further into the carpet fibers. Use the following steps along with the appropriate cleaning solution for your carpet type.

You Will Need:

• Cleaning solution
• Wool: 1 teaspoon mild, non-alkali detergent with 1 cup cold water
• Synthetics: 2 tablespoons household ammonia with 1 cup cold water
• Oriental: 1 part white vinegar with 2 parts cold water
• Clean white towels
• Spray bottle (for cleaning solution)
• Rinsing Solution:
  • 2-6 drops mild, non-alkali dish detergent with 1 cup cold water
• Water bottle

1. Begin by blotting with a clean cloth to remove as much of the blood as possible. It’s very important to BLOT throughout this entire process DO NOT SCRUB.

13. Remove weights and cloths and let area air dry.
14. When spot has dried completely, vacuum thoroughly to restore carpet texture and pick up any remaining cleaning solution residue.
15. If the spot turns brown when it dries, mix 1 part vinegar with 2 parts water. Apply the solution on the dried spot and blot to dry. This can be repeated ONE time.
