How do you use a natural descaler to remove limescale from a coffee machine, kettle or any other household appliance that uses water? Household appliances are often faced with problems linked to water, such as limescale. Most of the time, limescale deposits are very hard to remove. They build up in places that are hard to reach or even totally inaccessible (inside household appliances). It is recommended to prevent limescale building up by using the right descaling products and, if possible, natural descalers. When deposits build up and a natural descaler is not enough to remove the limescale, Laco also has a range of anti-limescale products to tackle more serious issues.
