I was unaware that my Silhouettes could be cleaned in place. I had tried a couple of cleaners and they said they could not do them. I called Hunter Douglas and was referred to a site that had Bayview On-Site listed. My questions were promptly answered and a service appointment was made and completed when promised. It is a pleasure to have found a company that offers a service and does a great job. I was getting tired of having to settle for sub-par service.
