I always run a cycle of filtered water in between pots, and also only make my brews with filtered water - as I live in a hard water area. In Italy we never use anything but water to clean coffee pots and makers.
If you prefer, here at Gevalia website, they sell a pot cleaner stuff called Cleancaf® Coffeemaker Cleaner. Click on Gifts and Accessories at the brown bar at the top of the page. Then "Accessories" from the drop down menu.
