How do I use the Café du Jour descaling powder correctly?

Dissolve 50 grams of the descaling powder in one litre of water. Pour this mixture into the water reservoir of your coffee machine. Allow it to work for 10 minutes, then let half of the liquid run through, switch off the machine for another 10 minutes, and then complete the cycle. Afterwards, rinse your machine at least three times with clean water to prevent any residual tastes. Always consult your machine’s manual for specific instructions.
