Dezcal Home Activated Limescale Remover, 4 servings per retail carton. Mineral scale in your hot water tank can clog the water flow and negatively affect the brewing temperature – resulting in an inconsistent brew. To prevent clogging and malfunction of the device, you should regularly descale the beverage device. Dezcal is a safe choice for removing scale deposits from your machine. Dezcal™ can be used on home coffee makers, espresso machines (both traditional and automatic), kettles and pod and pod coffee makers. NSF Certified for Metal Compatibility. Use quarterly for best results (water hardness in your area may
require more or less frequent descaling).
