The WoldoClean descaling tabs for fully automatic coffee machines are a simple and effective solution for removing limescale deposits in the machine. They are an efficient alternative to conventional liquid descaler. These tablets dissolve in warm water and reliably remove limescale inside the machine. The amount of descaling tablets required for a coffee machine depends on the amount of limescale and the size of the fully automatic machine. Many manufacturers recommend using one to two descaling tablets per 500 ml of water. Precise instructions on how to use the tablets can be found in the original operating instructions of the respective brands such as Siemens, Jura or Delonghi. These descaling tablets are also suitable for descaling other appliances, such as kettles, coffee machines or similar.
