Step 1: Decide the Solution you Are Going to Use

Already we have discussed four products that you can use to clean a coffee maker. Lemon juice, vinegar, and citric acid are all-natural. The commercial descaling products that are usually in powder, tablet, or liquid form may contain some chemicals and so you need to make sure that its all-natural when shopping.

If you decide to use vinegar, dilute it with water. Most of the commercial products come with specific instructions and steps on how to prepare the solution so check the package for these instructions.

They say rules are made to be broken, while this mantra may be true for some appliances, you cannot afford to experiment with your most treasured and valued kitchen appliance.

Step 3: Coffee Machine Descaler Rinse

Different Espresso machines have different features and capabilities, but the process of descaling is the same across board. Fill the reservoir with the cleaning solution that you prepared in Step 2 – the same way you add ingredients when making coffee.

Allow the solution to flow through the boiler and steam wand and finally out of the machine. As it flows through your espresso machine, all the gunk and other remnants from water will be dislodged, dissolved and washed away.

For example, if you regularly use hard water to make coffee, the minerals in the water will accumulate in the inner components thereby affecting the brewing temperature, reducing brewing flow, compromising the taste of the espresso as well as the power of the espresso machine.

If you have been using hard water, it is recommended to do the descaling process twice to be sure that all the gunk and other unwanted particles have been dissolved.

Step 4: Rinsing

Once you are satisfied that the descaling rinse process is complete, fill the reservoir again but this only with water. This step is very important as it ensures that all the vinegar, citric, or commercial descaling product you used is flushed out of the system. You definitely don’t want your morning cup of espresso before you leave for work to taste like citric acid.

Step 5: Smell the Water

To be sure that all the solution is out of the machine, sniff the water and if you even get a slight smell of the descaling solution, rinse it again. You can also use baking soda to test if the rinse water contains acids.
