The Advanced Stain and Odor Eliminator spray is designed to remove odors and stains left by cats. It cleans all types of biological fluids, including blood, urine, saliva, mucus, vomit, and more. This stain and odor remover is safe for carpets, hard floors, furniture, fabrics, and other surfaces when used as directed. It leaves a light, fresh scent. For hard surfaces, spray directly onto the stains, wipe with a clean cloth after 15 minutes, and let it dry for 24 hours. For carpets or fabrics with deep-set, old, or stubborn stains (such as feces or vomit/hairballs), gently scrub the stain with a soft brush for 1 minute, then allow it to dry for 24 hours. Do not use on hardwood, leather, velvet, silk, or special wool fabrics. The odor will disappear once the spray dries. Complete odor elimination occurs only if all odor sources are removed. If strong, old, or persistent odors remain on carpets or fabrics, dampen a towel with water and cover the affected area for 1–2 hours. This will allow bacterial enzyme activity to break down and eliminate unpleasant odors. 946 ml
