Urnex Tabz Coffee Equipment Cleaning Tablets are specifically designed to provide one-step cleaning functionality for coffee brewers and servers. By running a brew cycle with a Tabz tablet in the basket, users can simultaneously clean both the brew basket and the server beneath. Additional Tabz may be used directly in servers to quickly clean systems with multiple vessels. As an added safety feature, Tabz tablets contain a blue dye that helps ensure proper rinsing.
