I have been using Wolverine Carpet Cleaning for about ten years now and they just do a fantastic job. I have a white carpet that is about twenty years old. They have been taking care of it for a long time and it looks great. They come on time and they're just terrific. I had a couple of other cleaners come in and then I realized that Wolverine was the one doing a great job. Their customer service is also great. They're responsive, prompt and just perfect.
