As I have used probably everything on the market to remove pet stains purchasing from pet stores, etc., I was very skeptical.

The carpet in my den was ruined (I thought) since there was dog pee everywhere which has been there for years. When I used My Pet Peed the area started improving immediately.

I will say though that when I used the spray setting, it did not work as well as the stream setting. This may be because the stains were so old and set in.

This product did what it said so I would definitely recommend it.
