I had Naturewise Chem-Dry out a few months back to clean my carpeting. I thought the technician who came out was great, and I was pretty happy with the work he did. He was able to remove most of the pet odor, but it wasn't one-hundred percent gone. I was told I could call them back out to do another pass, but my dog ended up urinating on the carpet, so I worried they wouldn't honor it thanks to my dog. But other than that it was a good first experience, and I would use them again.
