Instant and permanent removal of pet urine stains is just a spray away with Woolite® Advantage Pet Urine Eliminator + Enzyme Action formula. It also works on other tough stains our furry friends leave behind, like feces, vomit and blood. But this formula doesn't just remove stains, it also eliminates odors using enzyme cleaning action and 25% more odor block technology*. The enzymes work continuously to destroy urine stains all the way to the backing** of carpet or upholstery while also preventing your pet from resoiling the area. It's safe to use on soft surfaces, like carpet, rugs and upholstery, as well as hard surfaces, like litter boxes, concrete, tile, and linoleum. Woolite® Advantage Pet Urine Eliminator + Enzyme Action is safe to use around kids and pets when used as directed and doesn't contain any phosphates, harsh chemicals or solvents.
