Descaling removes the mineral scale that builds up inside an espresso machine as hot water runs through it. Scale slows flow, hurts heating and can shorten the life of the machine, so regular descaling matters, especially in hard water areas.
The six products below include liquid and powder descalers, some made for specific brands. We have not used these products ourselves, so confirm every detail on the current listing before you buy. Always follow your machine’s manual first, since some makers advise against certain acids or require their own descaler.

Espresso Machine Descaling Kits FAQ
How often should I descale?
It depends on water hardness and use. Check the manual, since many makers give a schedule.
Can I use vinegar?
Some makers say no because it can leave odors or harm seals. Follow the manual.
What if my machine has a water filter?
Filters reduce scale but do not stop it, so descaling is still useful. Follow the maker’s guidance for filter changes.
Is filtered water enough?
Filters help, but they do not remove all minerals, so descaling is still useful.
