Delivery is very fast. I’m amazed at how well it removes pet stains. I was concerned about a strong odor after I sprayed the pee areas until I read how this product changes the pee to a gas. A well placed fan is very helpful for that. I have 3 Schnauzers who hate to go out if it’s raining and they are sneaky. Every rug I get they feel the need to pee on.
