Guide to Descaling your Coffee Machine

Coffee machine descaling is part of routine maintenance that cannot be avoided. It may seem like a nuisance but with a high-quality descaling solution, it is a quick and easy task that will leave your espresso machine cleaner and ensure it continues to produce great tasting drinks for years to come.

This guide takes a look at what kind of descaler is best and why so you can easily pick a product that works for you.


The ingredients of the descaler are important as the cleaner needs to be strong enough to deal with mineral buildups and scale as well as odours and stains. Citric acid based solutions are great for scale caused by hard water. If you are using soft water then you may find a non-acidic descaling solution works well. Whatever type of scale you are dealing with, it’s best to avoid options that include harsh chemicals such as phosphorus.

Choose Products That Are Made For Espresso Machines

Keep in mind that some descaling agents are more effective than others, some acid can be corrosive which is why it is important to choose a product that has been made specifically for use with coffee machines.

It’s important to choose descalers that won’t damage or corrode your machine as the product is being used to clean internal parts of the machine that are integral. If these areas corrode or become damaged it will be difficult to know the true extent of the damage until it is too late and it will be even harder to fix or replace these parts at home.

A note on vinegar: Although vinegar is sometimes considered a cheap, DIY descaler, avoid it. It is not a good idea to select vinegar to descale your espresso machine as it is very acidic and the acid can cause damage to the internal elements of a coffee machine.

It’s best to go with a citric acid or lactic acid based descaler as other formulas such as those that use vinegar have a strong odour. The odour of vinegar can be difficult to wash out of the machine and this will not only cause problems in the coffee maker but will also impact the smell and taste of your drinks.

Go for products that are odourless and make sure you rinse the machine a few times before you make a coffee after using a machine descaler.

Type Of Descaler

Descaler comes in many forms including powder, tablets and liquid. They each do the same job but the easiest option is liquid as this doesn’t need to be dissolved in water before using.

This makes it quicker and easier to use but make sure you check the instructions as the liquid descaler sometimes needs to be diluted in water before use.

Although liquids are more convenient to use, tablets and powder descalers are much easier to store as they take up less space and often have a longer shelf life.

There is branded descaler available for most of the big brand coffee makers, the good thing about this option is that you know the solution will work effectively with your specific machine.

There is a wide range of universal descalers available too, just make sure they have been formulated for use with coffee machines.


Descaling solution is available in a range of sizes from single-use kits to descaler that can be used for the next 4+ times descaling is required.

If you get a lot of use from your espresso maker then it may be worth buying a descaler that has enough solution for the next few times you need to descale.

This tends to be more cost-effective and will save you time too.

Signs Your Espresso Machine Needs To Be Descaled

Some espresso machines have an alert that lets you know when descaling is required. If yours doesn’t then you may want to keep an eye out for signs of a limescale buildup, these include:

  • Increased brewing time
  • Weak/ off-tasting coffee
  • Tepid water temperature when it should be hot water
  • Slow water flow

Descaling Vs Cleaning

Descaling and cleaning are two very different things. Descaling involves using chemicals to remove built-up minerals, scale and residue while cleaning is dealing with dirt and grime that can be wiped away.

Some kits come with descaler and cleaning tablets, these are handy as they help you give your espresso machine a thorough clean handling both the scale and any residue or dirt that may be inside your machine’s system.

How To Avoid Limescale Buildup

Use filtered water – the quality of the water being used in the machine makes a big difference when it comes to the build-up of scale. Using a water filter is an easy way for you to improve the water you are using and prevent scale from forming.

Have a regular descaling routine – rather than waiting for the scale to build up before doing something about it have a routine of descaling your espresso machine to prevent it from being a problem at all. If you descale your espresso machine every 2-3 months this can help keep it in top condition and will handle any limescale quicker and more effectively.
