Despite the popularity of coffee shops, brewing espresso at home is still the best way to make your favorite espresso drink. Espresso machines are widely available for purchase at a variety of stores and come in a wide range of prices, styles and brands. One of the more popular espresso machine brands is Krups. Like all espresso machines, Krups machines need to be properly cared for and will occasionally need to be decalcified. Calcification occurs when calcium deposits from water are left on the machine during normal use. Although these calcium deposits look difficult to remove, they can be easily removed in just a few steps.
Before decalcifying the espresso machine, fill the machine's reservoir with clean water and turn the machine on. Running plain water through the machine will remove any loose deposits from inside of the machine.
If using a commercial espresso machine cleaner, follow the manufacturer's instructions for mixing the solution with water. Add the solution to your machine and allow the machine to run one full brew cycle.
If you are not using a commercial espresso machine cleaner, a solution of vinegar and water can also be used. Mix 3 oz. of white vinegar with 20 oz. of clean water. Pour the solution into the machine's reservoir and allow the machine to run one full brew cycle.
After using either the espresso machine cleaner or vinegar solution, run the machine three or four times with clean water to remove any remaining residue. Finally, thoroughly wash and dry the espresso machine's carafe.
