Setup, Compatibility & Care
Setup:
The Stanley Classic Legendary Thermal Flask requires no complex setup. Before first use, it is recommended to wash the flask and lid with warm, soapy water. To maximize temperature retention, pre-heat the flask with boiling water for 10 minutes before filling it with hot beverages, or pre-chill it with cold water for 10 minutes before filling with cold beverages. Ensure the lid is securely tightened to prevent leaks.
Compatibility:
This flask is designed for beverages only. It is compatible with both hot and cold liquids, including water, coffee, tea, soup, and juices. It is not designed for carbonated beverages or for use with enzymes or strong oxidizing agents. The wide mouth is compatible with standard ice cubes.
Care:
Cleaning is straightforward as all parts of the stainless steel vacuum bottle are dishwasher safe. For manual cleaning, use warm, soapy water and a soft bottle brush. Avoid using abrasive cleaners, steel wool, or harsh chemicals, as they can damage the finish and insulation. Ensure the flask is completely dry before storing to prevent odors or mold. Store with the lid off to allow air circulation.
