Heavy Mineral Buildup
If you regularly boil tap water, you may eventually notice a white or chalky layer inside the kettle.
This is usually limescale, a mineral deposit commonly associated with hard water.
Limescale isn’t automatically a sign that the kettle is dangerous, but heavy buildup can affect the appliance’s performance and make cleaning more difficult.
Depending on the manufacturer’s instructions, regular descaling can help keep the kettle working efficiently.
Don’t use aggressive cleaning chemicals unless the manufacturer specifically says they are appropriate.
