HG Brill Descaler 500ml HG Hagesan Quick Descaler is a super concentrated, fast working product. HG Descaler will remove scale from the electric elements of kettles, coffee-makers, washing machines and hot drink dispensers. If allowed to build up, limescale and other deposits will make heater elements use more energy, meaning that it runs less efficiently and will wear out more quickly. Furthermore, in coffee makers, scale does nothing to improve the taste of the coffee. One bottle of HG Descaler is sufficient to descale an electric kettle up to 10 times. 500ml
