5.1. For Hot Beverages
- Pre-heat (Optional): For best results, pre-heat the flask by filling it with hot water for 5-10 minutes. Empty the water before adding your beverage.
- Fill: Pour your hot beverage into the flask. Do not overfill; leave some space at the top for the lid.
- Secure Lid: Tightly screw on the cap to ensure a leak-proof seal and optimal temperature retention.
5.2. For Cold Beverages
- Pre-chill (Optional): For best results, pre-chill the flask by filling it with cold water or ice for 5-10 minutes. Empty before adding your beverage.
- Fill: Pour your cold beverage into the flask. Do not overfill.
- Secure Lid: Tightly screw on the cap to ensure a leak-proof seal and optimal temperature retention.
6. Maintenance and Care
- Cleaning: The flask is dishwasher safe. For hand washing, use warm water and mild detergent. Use a bottle brush for thorough cleaning if needed.
- Drying: Always ensure the flask is completely dry before storing to prevent odors or mildew.
- Storage: Store with the lid off or slightly ajar to allow air circulation.
- Avoid Harsh Cleaners: Do not use abrasive cleaners, bleach, or chlorine-based products, as these can damage the flask's material and finish.
- Temperature Extremes: Avoid exposing the flask to extreme temperatures (e.g., freezing or direct flame) beyond its intended use.
7. Troubleshooting
- Leakage: Ensure the lid is screwed on tightly and correctly aligned. Check the lid's seal for any damage or debris.
- Poor Temperature Retention: Ensure the lid is securely closed. Pre-heating or pre-chilling the flask before use can significantly improve temperature retention.
- Odor Retention: Thoroughly wash and dry the flask after each use. For persistent odors, a mixture of baking soda and water can be used for soaking, followed by rinsing.
