If you've got pets, then the best way to use Hoover Oxy Pet Urine & Stain Eliminator is to treat the stain immediately with paper towels and water, then clean the whole area with your regular formula, then put this Oxy Pet formula in to spot clean. It really works great this way. I wouldn't use this to do a general full cleaning, so I do feel like a lot gets wasted, but it's a very effective product.
