Manufacturer's Recommendation: Always use the descaling product recommended by the manufacturer, especially if the machine has a descaling program. These programs have a fixed duration, and using the correct product ensures effective descaling.

Risks of Incorrect Products: Using a milder product might not be effective within the program’s duration, while a harsher product can damage the machine by causing corrosive damage to the plastic parts.

Alternative Descaling Method:

While vinegar is commonly recommended for descaling, it's not ideal for fully automatic machines as it can cause damage. Instead, use sulfamic acid, which is effective, gentle on seals and metal parts, and safe.

If you suspect mold in hard-to-reach areas, you'll need to open the machine. You'll find guides on how to do that in the subcategory of your model, here's one example: Saeco Minuto öffnen

Note for DeLonghi appliances: With these machines, the upper brewing piston should be descaled separately.
