Bests & Worsts Reviews from Amazon

I've got a little dachshund that has here occasional accidents in the house and sometimes I don't find them until they been there too long and the pee had dried into the carpet. I can find these buy using a blacklight. I've used the product as directed and cleaned the carpet. And while to the naked eye, it may appear that the stain is gone, if you put it under black light, you can see it's not. The way the product is described as being enzyme based and will break it down, once cleaned, in my mind, there should be no evidence that it ever happened, but that's not the case. I tested other cleaners out there with the same results. I bought this because I thought it was special or different, but that's not the case. The remnants of the stain are still there and I don't think there is any product out there that will change that. Just my opinion. My review is based on whether I would buy the product again or recommend it to someone else, and the answer to that is no.
