10 Best Coffee Descalers 2022

One of the biggest manufacturers of coffee machines in the world and this descaler can deal with the two most popular types of machine, too.

It is powerful to act against lime deposits in machines and dissolves calcium deposits up to three times more efficiently and faster than conventional decalcifiers, making it ideal for coffee machines.

The 500ml contents can completely clear a machine up to five times, so it is brilliant value and you will never run out before you have realised you need another bottle. Each measurement is measured out on the label so as long as you pour slow, you won’t use too little or too much.

Depending on the hardness of your water and your machine, one bottle should, therefore, last for around 6-12 months. It is much more cost-effective than the single-use sachets which De’Longhi offer and is a stronger solution than any of the non-branded options around.

It is suitable for all coffee machines but in particular the actual De’Longhi espresso and pod machines. The only downside is the lack of instructions on the actual bottle etc, but they have provided plenty of YouTube videos to guide you.

A descaler for the Lavazza A Modo Mia coffee machines, this is a single-use bottle which will fully remove any limescale deposits until the next time it is required.

Just tip the whole bottle into the water and follow instructions, and after a few flushes out, you should have a fully working machine again. Pod machines need a very specific water pressure to enable coffee to be forced out of the pod, so it is something which needs doing regularly.

Follow the instructions for your specific machine. While it is a bit pricey for a one-use bottle, it is a solution dedicated to pod machines so is the best stuff around.

Sage makes some of the best top-end coffee machines on the market, and if you invest in one of their models, you are going to want to make sure you keep on top of cleaning and that it lasts for its entire possible lifetime.

It will remove even the hardest limescale from their espresso and bean to cup machines, as well as their kettles. After it has been used, it will be like the machine is brand new again, and you will wonder how you ever coped with the slightly struggling water force.

You can also use it on other branded espresso machines, in case you want the absolute best for the one in the office. Other reviewers have commented that they only had to rinse the machine out once for there to be no taste and cleaning residue left over, which is a vast improvement on the usual three or four times which are required for poorer descalers.

It is a bit pricey in comparison to some other brands, but you’re paying for effectiveness, ease and power.

It is a brand known for its descalers, making products for dishwashers, kettles and irons.

So, when it comes to coffee machines, it is a safe pair of hands. It will work for all household machines and products, so buying a packet of three sachets will ensure everything in your home which touches water can be sparkling new.

It can work in just ten minutes, removing 100% of limescale. If used every three months, your products will always work as new. We think it would be best for pod machines and smaller filter machines, as it may not be powerful and dedicated enough to work on larger espresso or bean to cup models.

You could also use it on a gooseneck kettle if you have a pour-over method of coffee making.

Perfect if you have a professional-standard coffee machine, this cleaner is able to eliminate residue in heads, valves and lines, ensuring a really thorough service.

Whereas other cleaners may just go through the main parts of the system, this offers a full flush, prolonging the life of the machine. It is great if you have not been cleaning the machine as often as you should have been.

Because it is a professional standard cleaner, it is brilliant for commercial environments where you may not have much spare time to clean the machine through, but where the machine gets used hundreds of times per day.

Not only will there be no smell, but it will get your machine working faster and smoother if you have been noticing a bit of a lag.

Within the bottle is enough liquid for around six doses, which should give you around a year and a half worth of treatments. For ordinary machines and kettles, there is another HG Quick Descaler available.

It comes at a great price too, working out at an average of just £1 per use.

This cleaner is highly acidic, fighting through the toughest of build-ups.

It not only tackle these, but it can help to prevent future build-ups too, helping to maintain water pressure and consistent temperatures.

The cleaner is odourless, and it is suitable to treat all Keurig machines. It will also cope with most non-Keurig machines, of the single-cup brewers and automatic drip machines variety.

Every 420ml bottle will be able to deliver around 3 full cleans, so while it may be a little pricey, your machine will be clean for well up to a year.

One of the best big bottles, suitable for high-grade coffee machines and kettles.

It contains a special corrosion guard, so won’t only clear current calcium build-ups but will also protect against eventual wear of the unit and internal pipes. A measuring indicator is easy to follow on how much to use.

You can use the descaler up to six times overall. If it passes through the system and is still red, it can be reused, but if it is orange then all of the descaler power has been used up.

Just pour 125ml descaling liquid and 250ml water into the water tank, and let it run through. Repeat until there is no residue left. It has been designed to be gentle, so can be used in all variation of machine.
