4.2 Descaling

Over time, mineral deposits (limescale) may build up in the heating chamber, especially if using hard water. To descale:

1. Mix a solution of white vinegar and water (1:1 ratio) or use a commercial descaling agent suitable for baby products.
2. Pour the solution into the heating chamber, ensuring it covers any mineral deposits.
3. Let it soak for 30 minutes to an hour, or as recommended by the descaling agent. For stubborn deposits, you may gently heat the solution for a few minutes (do not boil).
