Why Descaling Is Necessary

These deposits can accumulate, clogging the water channel and hindering the coffee’s extraction process. When water flow is restricted, it cannot adequately saturate the coffee grounds, resulting in a less flavorful brew. Descaling is the solution to this problem, as it effectively removes these hardened mineral deposits.

  • A descaling solution (commercial descaling solution, white vinegar, citric acid, baking soda, or lemon juice)
  • A clean, empty carafe
  • Water
  • Safety precautions, such as gloves and protective eyewear
