To descale a traditional coffee machine (like Rancilio Silvia, Gaggia Classic, La Pavoni Europiccola etc.), carefully follow the instructions described in the user manual. In many cases, a common operation consists in completely emptying the water and residues left over after use (coffee pods or coffee grounds). To proceed with descaling it is therefore necessary to use a diluent mixture to add to the water in the tray. At this point it is mandatory to follow the instructions of the coffee machine model. These products are diluted with water, the mixture is poured into the basin, then the ignition is activated and the liquid is made to flow out until the water is exhausted. In some cases it is necessary to repeat the descaling cycle 3-4 times. Naturally it is necessary to put a large container instead of the cup. At the end of the descaling process it is a good rule to repeat the procedure using only water, to rinse off any residues of the mixture.
