Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Beverage not staying hot/cold for 24 hours | Bottle not pre-conditioned; stopper not sealed properly; damaged vacuum seal. | Pre-condition the bottle with hot/cold water before use. Ensure the stopper is twisted tightly. If the issue persists, the vacuum insulation may be compromised. |
| Leaking | Stopper not sealed properly; damaged gasket/seal. | Ensure the twist and pour stopper is fully closed. Check the silicone gaskets for wear or damage and replace if necessary. |
| Unpleasant odor/taste | Inadequate cleaning; residue buildup. | Clean all parts thoroughly with warm, soapy water and rinse well. For stubborn odors, a mixture of baking soda and water can be used, followed by thorough rinsing. |
