Your morning coffee loses all its appeal when the machine that makes it is dirty. Limescale, oily coffee residue and moisture build up little by little and end up affecting the flavour and even the working life of the appliance. In this guide we explain how to clean a coffee machine step by step, how to descale a coffee machine with things you already have at home, and what care each type needs, from the stovetop moka pot to capsule machines.
Why cleaning your coffee machine matters so much
With every coffee, small traces of oils and grounds are left inside the circuit, along with the limescale from the water. That mixture gradually sticks to the internal walls and to the heating element. The result is a more bitter coffee, a machine that takes longer to heat up and, in time, breakdowns that could have been avoided. Regular cleaning extends the life of the appliance and keeps the coffee tasting the way it should.
How often to do it
Not all cleaning is the same. It helps to separate daily upkeep from a thorough descale:
- Every day: rinse the parts that have been in contact with coffee and dry them well.
- Every week: wash the tank, the jug and the portafilter thoroughly with soap and water.
- Every one or two months: descale the inside to remove built-up limescale. If the water where you live is very hard, do it more often.
How to descale a coffee machine with vinegar
The best known and cheapest trick is white vinegar. Follow these steps:
- Mix one part vinegar to two parts water and fill the tank.
- Start the machine as if you were making coffee, without a capsule or ground coffee.
- Let half the liquid run through, switch it off and wait around fifteen minutes so it can work on the limescale.
- Finish the cycle and then run two or three tanks of clean water through it so no vinegar taste is left.
If you would rather not use vinegar, citric acid dissolved in water works just as well and leaves less of a smell.
How to clean a moka pot
The classic Italian moka pot asks for slightly different care. After each use, wait for it to cool and wash it with warm water only, without soap or metal scourers, which damage the aluminium and leave odd flavours behind. Check the rubber gasket and the filter now and then and replace them if they look dry or worn. If limescale appears, boil a mix of water and vinegar inside it and rinse well.

Capsule and automatic machines
Capsule machines and bean-to-cup models usually have their own descaling programme; it is worth following it. Empty and rinse the water tank daily, take out the used capsule drawer and clean the drip tray, where residue and moisture collect. Once a month, run the descaling cycle with the recommended product or with the water and citric acid mix.
Mistakes to avoid
With the best of intentions, we sometimes damage the machine. Take note:
- Don't put electrical parts in the dishwasher unless the manufacturer says you can.
- Don't use metal scourers or abrasive products: they scratch the surfaces.
- Don't leave standing water in the tank overnight, as it encourages limescale and bad smells.
- Don't skip the final rinse: a trace of vinegar can ruin the next coffee.
With these habits, cleaning the coffee machine stops being a chore and becomes a quick gesture you appreciate with every cup. A well-kept appliance lasts longer and makes far tastier coffee.
