Espresso machines use high heat and pressure to produce a delicious beverage. Hard water is a fairly common phenomenon in the home. Calcium and other minerals can accumulate in the fine tubing of espresso machines. Descaling the espresso machine ensures good extraction and proper operation of the machine. Cleaning the inside of the espresso machine removes hard water deposits, oil, and coffee grounds buildup.

How Espresso Machines Work
Understanding how an espresso machine works can help diagnose what is wrong when it is not functioning as it should According to Clive Coffee, an espresso machine is generally composed of four parts. These are the water source, pump, boiler, and steam wand, which can also be called the head of the group.
The water source is usually supplied by a tank for household equipment and a plentiful supply from a leaded source for commercial equipment. With a water tank, you can choose higher quality water, such as distilled or filtered water. On the other hand, espresso machines that use water from a main source are more prone to hard water problems.
Espresso machines make coffee from ground packets by forcing water under pressure to boil. The pump must work with a force as strong as about 130 psi to pass the water through the finely ground coffee bag. After coming into contact with the boiler and heater, the water rolls toward the head of the extraction unit and is poured into a waiting cup.

What is descaling? And why do you descale espresso machines?
The purpose of coffee machine descaling is to remove the calcareous deposits that form in the water flowing parts of the espresso machine.
Lime blooms are the off-white, calcareous residues that hard water deposits on the metal parts of the hydroelectric machine.
Mineral water or filtered water that contains high levels of dissolved minerals such as calcium and magnesium is a type of hard water.
The lime content builds up and hardens, making the heater less efficient.
This will limit the life and best performance of your espresso machine. Efficiency is reduced, resulting in higher electricity costs.
In addition, overlooked lime flower buildup can lead to espresso machine problems and increased maintenance costs.
Descaling Solution vs. Vinegar
If your espresso machine produces crackling water or no coffee, a clog could be the cause According to Espresso Parts, many pipes and small jets in espresso machines can become clogged with sediment. Scaling the espresso machine can remove the hard water deposits common in the network of pipes and parts of specialty coffee makers.
Cleaning espresso machines with vinegar is a safe and effective way to remove the natural oils and dyes that contaminate the surface. Descaling coffee machines with vinegar is easy and affordable. Mix 3 vinegar to 1 water and run the machine. Always check the manual to make sure the vinegar is a strong solution and will not damage the espresso machine. If you are unsure, reduce the vinegar to water solution to 1:1.
Commercial descaling solutions are effective for more complex machines and may be suitable for smaller household types. Home Ground recommends using a 100% natural, commercial machine descaling solution and always following the manufacturer’s recommendations.
Citric acid and lemon juice
It is also effective to descale espresso machines with citric acid. Concentrated citric acid in powder form, such as a sachet of unsweetened lemonade, is more effective than lemon juice. Mix the citric acid powder with water before running it through the machine. For initial cleaning, a mixture of 1 teaspoon of citric acid to 1 cup of hot water works well.
Caring for your espresso machine at home
It’s time to remove the lime scale, as there is no way to get rid of it once it builds up. To descale your espresso machine, use a specific product or read Listed below are some useful tips on how to descale an espresso machine at home using.
- Citric acid
- Sodium bicarbonate
Citric acid: natural and easy to use
Citric acid is used for descaling because it is natural, easy to use, readily available, odorless, inexpensive, has a low pH, and leaves no chemical residue.
Rather than using lemon juice, we recommend using concentrated citric acid in powdered form, such as unsweetened lemonade packets sold in supermarkets. In most cases, you will get better results than with pure lemon juice, and you will save yourself the trouble of squeezing the lemons yourself.
If your espresso machine’s boiler is made of aluminum, it may tend to stick to the inner walls. In this case, flush with plenty of water and use a different cleaning solution.
Cleaning Instructions :
-2 tablespoons food-grade citric acid
-1 liter of water (room temperature)
Mix citric acid and water in a pouring cup. Then pour the descaler for the concentration into the water tank.
Run the water through the machine so that the boiler is filled with acidic water. It is like making a new cup of coffee. Don’t forget to run the water through the steam nozzle.
You will notice that the color of the water coming out of the machine changes as you run the descaling solution. This is normal. This is the result of descaling. Discard the water.
Repeat this cycle until the citric acid descaling solution is gone. Fill the machine with plain water and run it. Discard the water. Repeat this procedure until the water runs clear. This will remove the citric acid taste from the espresso machine.
Once all steps are completed, your espresso machine is ready to brew your favorite espresso.

Recipe for Descaling Coffee Machines with Vinegar
Standard white vinegar, that’s all you need.
The difference between the recipe for coffee machine descaling using vinegar and the recipe for descaling using citric acid is that the vinegar is used directly.
There is no need to dilute it with hot water.
The procedure for descaling with vinegar is simple. Add vinegar to the water tank as you would prepare an espresso. Use a sufficient amount of vinegar as if you were making four or five cups of espresso.
This way, you can spread the vinegar throughout the entire espresso machine. Depending on the frequency of the descaling, the water that comes out may be brownish. Don’t forget to put the steam nozzle in the machine and clean it thoroughly, even down to the milk scum.
Next, you may want to fill the machine with fresh water and run it until the vinegar is no longer discernible. It may take several times until the vinegar is completely gone.
Lemons: effective and easy to obtain
If you don’t like the strong smell of vinegar, lemon is another option.
Lemons, like vinegar, have a cleaning effect. It is easy to obtain and has an extremely high level of acidity.
And if squeezing lemons is too much trouble, lemon juice sold in supermarkets is also effective enough.
Lemon Juice Descaler Recipe

What happens if I do not descale my espresso machine?
If an espresso machine is not descaled, hard water deposits can clog heating elements and water passages. This results in reduced water flow and temperature, poor extraction, and poor taste. Insufficient cooling can also damage internal components.
How do I clean the steam wand?
Wipe the steam wand with hot water and a sponge after each use and dry with a clean paper towel or napkin. You may also want to run a little steam through the wand to prevent milk from clogging the nozzle. The steam nozzle works best when the unit is filled with descaling solution.
Why clean the coffeemaker?
A coffeemaker that runs several times a week or even several times a day should be cleaned from the inside out about once a month. Impurities in tap or bottled water can accumulate and form deposits that eventually affect the function of the coffeemaker. Ground coffee beans contain natural oils that adhere to the walls of the carafe or filter basket after each brew.
In wet areas, bacteria and mold can adhere to the water tank and the pipes that carry water into the beans. Hot water will not kill the bacteria, nor will acidic coffee. To remove these stains and impurities from coffee makers and decanters, you need a good, natural, mildly acidic cleaner.
