Wolverine Carpet Cleaning does a great job of cleaning my carpet. I have been using them for four years. I keep using them because my carpet comes out so clean. They have also done upholstery for me and it always turns out great. The servicemen are courteous and pleasant; they really know what they are doing. I wouldn't use anyone else. If you want clean carpet and upholstery; give Wolverine Carpet Cleaning a call, and you won't be disappointed.
