Clean and maintain your bean-to-cup coffee machine: Key steps and products

Today we are going to discuss the key steps for cleaning your coffee machine! A clean and healthy machine will guarantee you a good cup of coffee every time.

Indeed, limescale, old coffee deposits and other unwanted residues can alter coffee extraction and of course, the taste of your coffee. If your coffee starts to taste differently, almost stale, then it is time to take this matter into your hands and finally clean your coffee machine!

In addition to experiencing an awful taste with your coffee, these residues will eventually damage your coffee machine. To avoid this eventuality, there are a few key steps in order to maintain your coffee machine that I highly recommend. I’ll give you my expert technics and secrets (regularity!)

Here are the steps to maintain your bean-to-cup coffee machine:

  1. Cleaning your Coffee Machine with White Vinegar
  2. Filtration
  3. Descaling
  4. Cleaning the Group Head of your Coffee Machine
  5. Cleaning the Grinding Burrs
  6. Cleaning the Milk System

Cleaning your Coffee Machine with White Vinegar

We all want eco-friendly and cheap solutions when it comes to cleaning our ustensils. As a results, a lot of people are wondering if they can clean and maintain this way their bean to cup coffee machines with white vinegar.

This product is made from natural ingredients and I often praise this product as it is multipurpose and very efficient.

However, you have to be careful with it! This is not a good idea for your bean-to-cup coffee machine.

The acetic acid contained in white vinegar isn’t compatible with the joints and the pipes of your coffee machine. Thus, after using it for a while, you will end up with leaks because the acetic acid will eat the joints and the pipes. Notes that this is obviously a damage criteria in the machine’s warranty.

So what now? Well, I would advise you to use products containing lactic acid, which is less abrasive and just as efficient on limescale.




water filter cartridgeFirst of all, it is necessary to filter the water of your bean-to-cup coffee machine because limescale is the number 1 enemy of espresso machines.

There are several methods:

  • integrate a water softener to your set-up
  • use a manual filtration with a water filter jug
  • or you can use filter cartridges directly plugged into your bean-to-cup coffee machine

These filter cartridges will directly filter the water in your coffee machine. It will eliminate the limescale and the impurities found in the water to protect your coffee machine and avoid any deterioration of your machine. Note that there no universal cartridges. Each manufacturer offer their own cartridge specific to their bean to cup machine.



descaler and cleaning product for coffee machines

Even if the cartridge is going to filter limescale, you will have a small amount that might still accumulate little by little in the pipes of your espresso grinder which will cause:

  • the dripping to slow down
  • your machine to overheat due to an energy overconsumption

This is why I would highly recommend using a descaler/decalcification solution.  Use it at least once or twice a year (if you are already using a filtering cartridge) and up to once a month if your water is very hard (if you choose not to filter your water).

Most of the major brands of coffee machines will urge you to use their own product but note that there are many universal descalers out there which can adapt to all bean-to-cup machines.

You can find liquid descalers or descaling tablets. I don’t have any preferences! It’s up to you to determine what suits you best, depending on your habits and above all the procedure of your coffee machine.

Cleaning the Group Head of Your Coffee Machine

The more you use your coffee machine, the more ground coffee and coffee oil deposits will appear around the group head and pipes of your machine. These residues will turn the taste of your coffee stale as they will mix during the coffee extraction. To avoid this outcome, you need to clean your group head at least once a week!

Two solutions:

  • if you can extract the group head (which is the case for most machines) : all you need to do is rince the infuser with warm water once a week and let is dry completely before putting it back. For a deeper clean, you can clean your infuser with a descaling tablets you can put in the ground coffee reservoir.
  • if you can’t extract the group head, which is the case of Jura’s coffee machines, then you can use cleaning products directly in the ground coffee reservoir. It will clean your machine entirely and your coffee will be safe!

Cleaning the Grinding Burrs

If you want to maintain your bean-to-cup coffee machine properly, you cannot overlook your grinder. Indeed, it is the core of your machine. As you know, coffee releases oil when grinded. Coffee oil and coffee dust can accumulate around the grinding burrs whether it is made with stainless steel or ceramic.

It is therefore necessary to clean the grinding burrs in order to maintain your coffee machine and the taste of your coffee. You’ll only need to use SuperGrindz cleaner by Urnex which will clean out all grease and residues. This cleaner is also made with 100% natural ingredients and is gluten-free. See our video to find out more about how to use it.

Cleaning the Milk System

cleaning the milk system of your coffee machine

Your coffee machine allows you to prepare milk-based drinks? It is then very important to clean the milk system. Let’s keep it hygienic! No one wants to end up with a sour taste of milk in their cappuccino. So, in order to avoid bacterias in your coffee or worst case scenario food poisoning, let’s clean your milk system properly!

For this, you need a good cleaning product for your milk system. It will remove the milk residues and clogging from the system.

Indeed, milk can also clog in the pipes and especially in the milk frother which will affect the quality of the taste and texture of your milk foam. Some machines will automatically rince hot water in the milk system with the function “rinse milk system” to clean any milk residues. Note that this function only “rinces”. Consequently, I would highly recommend you using a cleaning product to make sure to remove 100% of the bacteria.

You now know all the key steps and products to maintain the quality and the life span of your bean-to-cup coffee machine! Nothing too difficult, just some regularity with the right product. See all our cleaning products to help you on MaxiCoffee.

    I completely disagree with this article – my italian flatmate who uses her granny’s expresso pot taught me that the years of brown residue made the coffee taste – rather than the bitter taste of cleaners and un-used metal pots. When I buy a new pot now I brew in it to achieve the patina

    I too was told the same by an Italian friend in Florence some years ago. And I think it right to some degree. But bear in mind this obviously concerns this particular type of espresso pot brew !
