Urnex Dezcal Home Activated Descaler Urnex Dezcal Descaling Powder The build-up of mineral scale is a threat to the performance and durability of coffee and espresso machines. Mineral scale build-up can impact your machine’s boiler, preventing water from reaching its optimal brewing temperature. At insufficient temperatures, it is impossible to extract the full flavor from your coffee beans. Mineral scale build-up can also clog water flow, and if not removed, can cause a machine to stop working. Descaling removes the mineral scale build-up that forms on the heating element of all coffee equipment. Dezcal Descaling Powder is odor free and rinses away thoroughly, unlike vinegar which can be difficult to rinse, takes longer to be effective and leaves behind an unpleasant odor and aftertaste that affects the aroma and taste of your coffee. Safe - Non-toxic, biodegradable descaling powder Effective - For fast and effective descaling of boilers and heating elements, removes limescale Multi-Use - For use with home coffee brewers, espresso machines, pod machines, capsule machines, kettles, garmet steamers, and domestic irons No Vinegar Smell - Removes limescale from heating element without the vinegar smell For Complex Maintenance - For complete maintenance use with Urnex Coffee Machine Cleaning Powder Instructions for Use: Dissolve 1 packet (28 g) of Dezcal Descaling Powder per 32oz (1L) of lukewarm water. Pour solution into water reservoir. Brew full reservoir. Discard solution. Rinse all parts and repeat with clean water 3 times. Note: Be sure to use caution on countertops as this acid formula can have a similar effect as that of lemon juice. For best results, use quarterly (water hardness in your area may require more or less frequent descaling).
