Nature's Miracle Advanced Stain & Odor Remover combines the best cleaning technologies to create the most effective, pet-safe formula available. This advanced oxygen infused, bio-enzymatic formula deeply penetrates to eliminate tough pet stains and odors including pet urine, vomit, feces, and blood, discouraging the spread of unsanitary pet waste. The dual-action Pet-Block system removes pheremones (attractant scents released by pets), and destroys odors on contact to prevent resoiling. Faster drying formula helps minimize tracking. Safe for use around children and pets!
