- Descaling: Mineral deposits (limescale) can build up over time, especially with hard water. Descale the warmer regularly (e.g., once a week or every few days depending on water hardness).
- Mix 50ml of white vinegar with 100ml of water.
- Pour the solution into the heating chamber.
- Let it stand for 30 minutes to 1 hour (or longer for heavy buildup).
- Empty the solution and rinse the chamber thoroughly with clean water.
- Run a sterilization cycle with clean water to remove any residual vinegar smell.
- Storage: Store the clean and dry warmer in a cool, dry place.
