Mix 1 cup hydrogen peroxide, 1/4 teaspoon of dish soap, and 1 tablespoon of baking soda in your favorite spray bottle. Spray the solution onto the area of the odor and let dry. Vacuum up the leftover baking soda. This works great on pet urine and vomit. The hydrogen peroxide kills any odor causing bacteria and the baking soda soaks up any other odors like the ammonia smell left from urine. Hydrogen peroxide can fad some fabrics so test first.
