The water softener can improve the cleaning power when used in combination with soap nuts for a high or very high degree of water hardness. Soap nuts require soft water to achieve optimum results. Limescale deposits attach to textiles and washing machines, leaving behind a greasy film.

Dosage:

• Water hardness 3 (hard): 20 ml (2 tablespoons)
• Water hardness 4 (very hard): 30 ml (3 tablespoons)
