I first used Renaissance Rug when I was moving, I thought it would be great to start with clean rugs in my new home. I was stunned at how inexpensive they were, I had used another rug cleaner previously and they did not measure to Renaissance. Recently a dog decided my very old oriental rug would be a nice soft place to relieve herself. Thank goodness for Renaissance, I knew right where to take the rug. These guys are top drawer (excellent).
