Removing feces stains can be done by first scooping up any excess feces. You can do this with either an old spoon,spatula or even some old newspaper. Then you can create a mixture using 2 tablespoons of ammonia to one cup of water,then you would blot the stain to remove the leftover residue and rinse with cold water.
Repeat if all of the feces stain is not removed. To remove lingering carpet odors from pet feces, sprinkle baking soda on the stain. Let the baking soda sit overnight, and then vacuum.
