Awesome stuff! We bought this as we have two puppies potty training, but have found many other clean-up uses for this product. A large potted plant was overwatered and leaked onto our tile and grout, leaving a huge area of dark stain. We tried everything to clean the grout to no avail. I saturated the area with My Pet Peed and just left it to dry. Within 48 hours, every trace of the stain had disappeared. Amazing product! Bonus, no scrubbing
