What is Water Scale?
Water scale is created when the mineral deposits in your water builds up. After the water boils away, the mineral deposits accumulate and create small hard deposits that can clog up your espresso maker and affects its performance.
Now you might be saying, “Well, why don’t I just use distilled water to make my coffee?” Using distilled water can help you avoid water scale buildup, but it also makes flat coffee because all the minerals have been removed.
Here’s the funny thing: the best water to use to making coffee is plain tap water! As long as you live somewhere with potable tap water, it’s perfectly safe and even cost-effective to use tap water for making your coffee.

When Should You Descale Your Espresso Machine?
The schedule that you should use to descale your espresso machine depends on the type of water that you use and the frequency that you use your espresso machine.
