How to descale a Nespresso machine in 2026

Scale is formed on the surface of a Nespresso when the water used to make coffee evaporates, leaving behind a buildup of heavy minerals.

These minerals are calcium carbonate deposits, which can impact the efficiency of a Nespresso machine by affecting the taste and texture of the beverage or causing the device to become clogged.

Descaling a Nespresso machine is essential for achieving an excellent flavor and prolonging the machine’s lifespan.

The following section offers an in-depth, step-by-step guide on seven effective ways to eliminate limescale in a Nespresso machine.

1. Use a specialized Nespresso Descaling Kit

Nespresso recommends using its Descaling Kit to descale your machine.

The kit comes with a Nespresso machine and includes two 100ml (3.38oz) descaling bags, made with citric acid, to dissolve scale without damaging machine components.

The descaling kit contains everything you need to descale the appliance and is suitable for removing limescale from various Nespresso machines.

You should take the following steps to descale your Nespresso machine when using a Nespresso Descaling Kit:

1. Disassemble the appliance and give it a thorough wash. Remove the Nespresso’s lid, drip tray, and capsule container, and wash them with warm water. This preliminary cleaning will help you eliminate some limescale and make the descaling process more effective.
2. Wipe down the body of the Nespresso machine and reassemble it. Clean the body of the Nespresso using a damp, soapy cloth, but only reassemble the components once they have completely dried.
3. Get your Nespresso Descaling Kit ready. Fill your machine’s water tank with 3.38oz (100ml) of Nespresso’s descaling liquid, then fill the remaining space with clean water.
4. Put your Nespresso machine in Descaling Mode. Putting your Nespresso in Descaling Mode is a simple process, but the method varies for different Nespresso devices. The latter part of this article provides clear instructions on how to activate the descaling mode for popular Nespresso machines.
5. Begin the descaling process. Press the button to start the descaling process and allow the descaling agent to work its way through the machine, filling your cup. Afterward, pour the cup’s contents back into the water tank to repeat the rinse cycle.
6. Repeat the descaling process using clean water. This process helps eliminate any residues of the descaling chemical, cleans the water tank, and cleans the inside of your machine. Go through this process at least three times to make sure the inside of your Nespresso machine is spotless.

Using a Nespresso kit to remove limescale is the easiest way to perform the descaling process.

You can get a Nespresso Descaling Kit if you've already used up the kit that came with your Nespresso machine.

The descaling liquid comes prepackaged and is specially formulated to prevent damage to your appliance.

2. Use a descaling fluid

Other descaling fluids on the market work well for all types of coffee-makers, including Nespresso machines.

Although some may not be as effective as Nespresso descaling agents, they can get the job done.

You should avoid harsh agents and refrain from using concentrated amounts of descaling fluids, as these can damage the Nespresso machine.

You should take the following steps to descale your Nespresso machine when using a descaling fluid:

1. Select a descaling fluid. There is a wide range of suitable descaling fluids online. The Impressa Coffee Machine Descaler is a good choice because it's gentle enough on Nespresso machines.
2. Fill the tank with the descaling solution. Add 17oz (500ml) of water to no more than 4oz (118ml) of descaling fluid.
3. Place a large bowl under the coffee outlet and select your Nespresso machine’s descaling mode. The descaling solution will pass through the appliance and into the bowl you previously put under the coffee outlet.
4. Refill the water tank with the contents of the bowl and repeat the descaling process. After the fluid has made this second cycle, you can dispose of it.
5. Finish the descaling process using clean water. This stage is the rinsing step, which will help clean the machine and remove any remaining chemicals and limescale. To thoroughly clean your Nespresso machine, repeat this rinsing process at least three times.

After you have finished descaling, exit Descaling Mode, reset your Nespresso machine, and it’ll be ready to use again.

Ensure that you mix the water and descaling fluid in the correct proportions.

The descaling process will be ineffective if you dilute the descaling solution too much.

However, making the solution too concentrated may cause severe damage to your Nespresso machine.

3. Descaling Nespresso with vinegar

Vinegar is one of the most popular homemade descaling solutions used in the United States.

Aside from being a cost-effective descaling fluid alternative, vinegar works as well as most commercial descaling fluids when used appropriately.

You should follow the procedures below to descale your Nespresso machine when using vinegar:

1. Fill the tank of your Nespresso machine with 4 cups of undiluted Vinegar. I recommend using natural vinegar, such as Heinz All-Natural Distilled White Vinegar, for the best results.
2. Allow the vinegar to stand for 30 minutes. Allowing the vinegar to stand is an integral part of the descaling process, as it allows the vinegar to work effectively.
3. Set the Nespresso machine to Descaling mode. You can begin the descaling process as with a normal descaling fluid.
4. Rinse the Nespresso machine by repeating the descaling process using clean water. Repeat the rinsing process as many times as possible or until the vinegar smell is gone. However, change the water each time to ensure the vinegar doesn't cycle back into the machine.

The only drawback to using vinegar to descale a Nespresso machine is the lingering smell it leaves behind.

However, if you rinse your machine thoroughly, you won't have a vinegary aroma in your next cup of coffee.

4. Use citric acid

Citric acid is one of the active ingredients used in descaling agents present in Nespresso Descaling Kits.

Citric acid’s pH is lower than that of vinegar, making it an excellent substitute for commercial descaling liquids and vinegar.

You can descale your Nespresso machine using citric acid by following this procedure:

1. Prepare the citric acid descaling solution. Add water and one tablespoon of citric acid powder to a bowl and stir the mixture well.
2. Pour the solution into the tank of your Nespresso machine. Make sure not to fill up the tank to the brim so it doesn't spill.
3. Start the descaling process. Remember to set your Nespresso machine to Descaling Mode. Throw out the fluid collected after the descaling process.
4. Fill the tank with clean water and restart the descaling process. Repeat this process until the tank is spotless.

Unlike vinegar, citric acid won't leave any strange odors in your Nespresso machine when used to descale it.

The Roots Circle All-Natural Citric Acid is a sensible choice of citric acid for general household cleaning and Nespresso descaling.

5. Use baking soda

Baking soda is a fantastic choice for DIY descaling remedies. It's cheap and leaves no aftertaste or residual scent.

Furthermore, baking soda will descale a wide variety of Nespresso machines.

You should follow the procedures below to descale your Nespresso machine when using baking soda:

1. Prepare the descaling solution. Fill a bowl halfway with water and dissolve ¼ cup (59.14 ml) of baking soda in it. Ensure that the baking soda has dissolved completely before pouring it into the machine.
2. Pour the baking soda solution into the tank of the Nespresso machine. Don't overfill the tank, as baking soda mixed with coffee residue can form bubbles.
3. Set your Nespresso machine to Descaling Mode and start the descaling process. Get rid of the used water after it’s expelled.
4. Fill the tank with clean water and rerun the descaling process. Repeat this process until the water in the Nespresso tank is completely clean.

Pure Organic Ingredients Sodium Bicarbonate is suitable for cleaning and descaling activities.

It's 100% pure food-grade baking soda, so you don't have to worry about any potential toxins.

6. Use a water softener

Limescale is caused by hard water, and using a water softener is a viable method to eliminate the deposited minerals in a Nespresso machine.

Morton Potassium Chloride Water Softener Pellets are excellent water softeners suitable for use with Nespresso machines.

When using a water softener to descale your Nespresso machine, follow the manufacturer’s recommended steps on the product packaging.

Some water softeners may not be suitable for Nespresso machines, so it is preferable to buy ones rated for home appliances.

Descaling using water softeners can be challenging because numerous types of chemicals are available.

Nespresso machines are especially vulnerable to certain water softeners since they can clog the small apertures in the appliance and prevent water from flowing. So, using a water softener should be your last resort.

7. Use lemon juice

Lemon juice is another cheap method of descaling Nespresso machines.

Lemon juice, although unconventional, is safe and eliminates the danger of clogging your device, which can't be said for baking soda and water softeners.

It also smells nothing like vinegar and is suitable for people who can't stand the nasty scent it leaves.

Here's how to descale your Nespresso machine using lemon juice:

1. Add a mix of water and lemon juice to a bowl. The descaling solution should be a mixture of equal parts water and lemon juice.
2. Fill the tank of the Nespresso machine with the lemon mixture. Use filter paper while pouring the fluid into the machine, but take care not to let the solution spill.
3. Allow the mixture to remain undisturbed for 25 minutes. Allowing the fluid to sit will enable the lemon juice to work as a descaling agent.
4. Activate Descaling Mode on your appliance. Run the descaling process as normal and empty the collected fluid.
5. Rerun the descaling process with clean water. Repeat this rinsing process until all traces of the solution are gone.

Natural lemon juice is best suited for descaling. The main disadvantage of this method is that you have to squeeze a lot of fresh lemon juice.

Thankfully, you can also use the bottled kind for descaling.
