Being able to make a good cup of espresso every single day is one of the best parts of waking up.

Cleaning the espresso machine from the inside is also called as descaling.
Descaling coffee machine aims to remove the lime scale deposits that build up on the espresso machine, particularly on the parts where the water flows.
Lime scale is the chalky, stony, off-white residue left behind by hard water on the metallic parts of water-operated machinery.
Mineral water and filtered water, which contains higher concentration of dissolved minerals like calcium and magnesium, are some samples of hard water.
When the lime scale builds up and hardens, this slows down the efficiency of your heating element.
Given the reduced efficiency, this will cause you higher electricity bill.
And if you overlooked the extensive lime scale build up, expect for higher maintenance cost of your espresso machine.
Since limestone build ups do not help, in any way, we should learn how to get rid of it.
I listed below helpful tips on how to descale espresso machine at home.
Citric Acid is often used in descaling because it is natural, easy to use, easy to find, odorless, relatively cheap, has lower pH level and doesn’t leave chemical residues.
Citric Acid Descaler Recipe:
First, just mix the Citric Acid and water thoroughly in a pouring cup. Then pour the citric acid descaler concentration on the water reservoir.
Run the water through the machine to get the boiler filled up with the acidic water. It’s as if you are brewing a fresh cup of coffee. And, don’t forget to run the water through the steam wand, too.
After running the citric acid descaling solution, you will notice the off-colored water coming out of your machine. It’s normal. That is the result of descaling. Discard the water.
Repeat the cycle until you run out of citric acid descaling solution.
Then, refill and run your machine with plain water. Discard the water again. Repeat procedure until the water becomes clear.
This will remove the taste of citric acid from your espresso machine.

Since baking soda is non acidic, some say this cannot help in descaling your coffee machine.
Plus, baking soda doesn’t completely dissolve in water. So, others do not consider using this.
While some say the opposite, others who tried baking soda say it is a wonderful cleaning tool for their coffee machine.
Fur sure, baking soda is a great cleaning agent for the exterior and removable parts of your espresso machine.
Baking soda is widely available, very cheap, and doesn’t leave foul smell on your coffee machine.
How often descaling depends on the type of your machine, how often you use your coffee machine, and how hard the water is in your area.
Each machine has a guide from its manufacturer. So, it is safe to follow the guidelines there.
And if the machine is still under warranty, have it checked before descaling on your own.
As a general guideline, if you use your coffee machine for personal consumption only, descaling once a year is fine. But, heavy users might need to descale twice a year.
However, if you live in an area with really hard water, you might need to do it on a monthly basis.
You just have to check your machine, and if there’s a limescale build up, that’s the time you need to descale.
To be able to have a consistent good quality coffee, and to protect the life span of the espresso machine, descaling is a must and you will really benefit by knowing how to clean espresso machine at home.
You may choose from citric acid, vinegar, lemon, or baking soda, if you’re planning to do all-natural homemade descaling solution.

Some aficionados prefer vinegar, since it is a tried and tested cleaning tool. But with the flip side that vinegar has very strong smell which might affect the aroma of the coffee.
