I have a girl that has peed on my area rug to the point it couldn't be saved and I had to buy a new rug. A month or so ago, she peed twice on the new rug and I tried baking soda, enzyme spray, everything you can think of and my friend suggested a product called Furry Freshness so I tried it and it worked! It is a little costly but I have gone through a couple rugs and not being able to get the urine smell out and this stuff was like magic and saved me from having to buy yet another new rug. I had to use several applications but there is no lingering urine smell whatsoever and I highly recommend this product!
