To enjoy your purchase for a long time, please adhere to the following guidelines for using your LEIFHEIT thermos:
1. The push-button allows for easy one-handed use.
2. Rinse thoroughly and clean with lukewarm water before use. Do not wash in a dishwasher.
3. To open the thermos, turn the top counterclockwise.
4. For better heat or cold insulation, rinse the thermos with hot water before pouring hot drinks and cold water before pouring cold drinks. Never use a microwave or oven to heat the thermos.
5. Better insulation is achieved when the thermos is filled with liquids. For instance, hot coffee stays warm for around 20 hours under these conditions. The thermos should not be utilized for keeping warm dairy products, baby food, or carbonated beverages.
6. Cleaning the thermos:
Outside: Rinse with clean water, using a liquid cleaner if necessary.
Inside: Only rinse with clean water. Tea and coffee residues can be easily cleaned with denture cleaner. Rinse thoroughly after cleaning. Never immerse the thermos completely in water.
7. A better seal between the glass thermos and the surrounding shell can be obtained by tightening the screw at the bottom of the thermos. This should be checked periodically.
8. The thermos must not be used for ice storage. Do not drink directly from the thermos.
9. Avoid large temperature fluctuations inside the thermos.
10. LEIFHEIT provides a 3-year warranty for this thermos.
