What is a descaler?

A descaler is a chemical solution or device that is used to remove limescale buildup from appliances or plumbing fixtures. Limescale is a hard, white mineral deposit that can accumulate on surfaces that come into contact with hard water. This buildup can cause appliances to work less efficiently and can also lead to damage or corrosion over time. Descalers typically work by chemically breaking down the limescale so that it can be easily removed. Some descalers come in liquid or powder form and can be added to water or directly applied to affected surfaces. There are also descaling devices, such as electric descalers or magnetic descalers, which use electronic or magnetic fields to prevent limescale buildup. Descalers are commonly used on appliances such as coffee makers, washing machines, and dishwashers, as well as on plumbing fixtures such as faucets and showerheads.
