All you have to do is spray this on the stain, let is sit for 5–10 minutes, blot it up, then let it air dry. If you’re dealing with a deep odor problem, pour a generous amount on the area, let it stand for at least an hour, then lay a towel on top with a weighted object to absorb all the excess liquid.
Promising review: “I have an elderly dog who has occasional accidents and a cat with chronic bladder issues. Without this product, I’m pretty sure I would’ve burned down the house. On fresh accidents, it works with just one treatment. It removes the stains, and more importantly, it completely removes the odors. On older, setting stains, it completely removes stains and odors after several repeat treatments. I’ve tried so many products over the years. Hands-down, this is the best.” —SR Kelly
