Maintenance
1. Daily Cleaning
After each use, empty any remaining liquid. Disassemble the lid and remove the silicone ring.

Rinse all parts well and allow them to air dry completely before reassembling or storing.

2. Descaling
Over time, mineral deposits may accumulate inside the heating plate. To descale, fill the container with a mixture of water and white vinegar (1:1 ratio) or a commercial descaling solution. Let it soak for 30 minutes to an hour, then heat the solution for a few minutes. Pour out the solution, rinse thoroughly several times with clean water, and wipe dry. Perform descaling regularly, depending on water hardness and frequency of use.
3. Storage
Store the bottle warmer in a clean, dry place away from direct sunlight and extreme temperatures. Ensure all parts are completely dry before storage to prevent mold or mildew growth.
