Size: 32oz Spray Bottle Eco-88 permanently removes the toughest pet stains & odors plus it completely fragrance free. The only stain and odor treatments available to pet owners have been enzyme type products. It has been proven that enzymes work only in the most ideal of conditions. Eco-88 is not an enzyme or just another spot remover. With the utilization of oxygen, Eco-88 tears down the odor causing gas molecules to elemental compounds that have no odor, therefore, removing both stains and odors regardless of the condition.
