This video is a tutorial on how to remove blood stains on the carpet. The first step is to mix 1 teaspoon of dish detergent with a cup of water in a spray bottle. Spray your mixture on the stain and blot gently with a rag. Be careful not to soak the stain so it doesn't go through to the other side of the carpet. The second step is to mix 1 teaspoon of ammonia with a cup of water in a spray bottle. Once again, spray onto the stain and blot gently until the stain is gone. The third step is to use water to rinse off the chemicals.
