How many tablets to descale a coffee machine?

The number of descaling tablets needed for a coffee machine typically depends on the brand, model, and capacity of the machine, as well as the severity of limescale buildup. However, a general guideline is to use one descaling tablet for every 500ml of water tank capacity.

For example, if your coffee machine has a water tank capacity of 1 liter (1000ml), you may need to use 2 descaling tablets. It's always a good idea to consult the manufacturer's instructions or user manual for your specific coffee machine to get the most accurate recommendation.

Some coffee machines may come with their own proprietary descaling solution or tablets. In such cases, it's important to use the recommended product to ensure the safety and effectiveness of the descaling process. Avoid using generic descaling tablets or household cleaners unless they are specifically approved by the manufacturer.
