Our guy has gotten older and we went through several periods where he peed in the kitchen in the middle if the night. The pee would sit for hours, soaking into the wood at the base of our cabinets. Although we were able to deal with the visible problems, every time we ran the dishwasher the entire house smelled of hot, rank dog pee. Gross. I got the 32oz bottle and over the course of several applications, the smell is gone. I poured the product around the base of the cabinets and let it soak in. Yes, the smell was initially A LOT WORSE, but patience was rewarded! I was seriously considering replacing my base cabinets, flooring, and dishwasher. This was much cheaper!!!!
