Accidents happen, as every dog owner knows. Nature's Miracle Stain & Odor Remover Foam enzymatic formula produces enzymes when it comes into contact with a food source - pet urine, feces, vomit and other bio-based messes. The enzymatic cleaner will continue working as long as the food source is present. When used and stored as directed, the foam penetrates down into carpet to power out tough messes. This spot remover is tough on dog urine, feces, vomit, drool and other organic stains and odors, while freshening with a light citrus scent. This product is safe for your pets and home, when used and stored as directed. Trust Nature's Miracle products when finding solutions for a clean home and a happy, healthy pet.
