Mineral scale buildup threatens the performance and durability of coffee and espresso machines. Mineral scale buildup can impact your machine's boiler, preventing the water from reaching its optimal brewing temperature. At insufficient temperatures, it's impossible to extract the full flavor of your coffee. Mineral scale buildup can also obstruct water flow and, if not removed, can prevent the machine from functioning. Descaling removes mineral scale buildup that forms on the heating element of all coffee equipment. Dezcal descaling powder is odorless and rinses thoroughly, unlike vinegar, which can be difficult to rinse, takes longer to be effective, and leaves an unpleasant odor and aftertaste that affects the aroma and taste of your coffee.
