How can you prevent white layers inside kettles?

To prevent white layers inside kettles:

- Descale regularly: Use a descaling solution made of white vinegar or citric acid water once a month to dissolve limescale buildup.

- Use filtered water: If your water is hard, use a water filter to remove impurities that contribute to scale formation.

- Wipe down the interior: After each use, wipe the inside of the kettle with a damp cloth to remove water droplets and prevent scale from forming.

- Rinse thoroughly: Rinse the kettle thoroughly after each use, especially if you live in a hard water area.

- Avoid boiling dry: Never allow the kettle to boil dry as this can cause the heating element to overheat and damage the kettle.

- Use a kettle filter: Some kettles come with a removable filter that collects minerals and prevents them from building up inside the kettle.
