We've had a Bonavita 1900 for years. I've cleaned it with vinegar, but noticed lately that it was taking 20 minutes to brew 8 cups of coffee. I read about descalers and bought this product. You'll get two bottles in one order and each bottle is good for two cleanings. Followed the directions and cleaned my Bonavita twice. Our coffee maker is now making coffee in about 9 minutes, so a dramatic improvement! Unfortunately I can't get a Moccamaster now, but I'm happy that we'll get more use from the Bonavita.
