Read the manufacturer’s instructions: Different coffee machines may have specific descaling instructions, so it is crucial to consult the user manual before proceeding.

Prepare the descaling solution: Follow the instructions on the descaler packaging to prepare the solution, whether it is a chemical descaler or a natural descaler.

Empty and clean the coffee machine: Remove any coffee grounds or filters from the machine and ensure it is empty and clean before starting the descaling process.

Run the descaling cycle: Depending on the coffee machine, there may be a specific descaling cycle or program. Follow the instructions to initiate the descaling process, allowing the solution to circulate through the machine.

Rinse the machine: After the descaling cycle is complete, thoroughly rinse the coffee machine to remove any residue or remaining descaler solution.

Perform a test brew: Before making your next cup of coffee, run a test brew to ensure that all traces of the descaler have been removed.

Frequency of Descaling

The frequency of descaling depends on various factors, including the hardness of the water used, the frequency of coffee machine usage, and the manufacturer’s recommendations. As a general guideline, it is recommended to descale your coffee machine every three to six months.

However, if you notice a decrease in performance or a change in the taste of your coffee, it may be necessary to descale more frequently.
