While primarily designed for cold beverages, the vacuum insulation can help maintain the temperature of hot drinks for a period. However, focus is on cold retention.

Ensure the lid is fully sealed and the straw is properly inserted. Check if the double-wall vacuum insulation has been compromised (e.g., by dropping the tumbler). For optimal performance, pre-condition the tumbler by filling it with hot or cold water for a few minutes before adding your desired beverage.

Ensure the lid is aligned correctly. Sometimes, slight pressure or a gentle twist can help it seat properly. Make sure there is no debris obstructing the mechanism. If the straw is removed, ensure the opening is clear.

Wash the tumbler with warm, soapy water and a bottle brush. For stubborn stains or odors, try a mixture of baking soda and water, let it sit for a few hours, then rinse thoroughly. Ensure the tumbler is fully dry when storing.

This can occur with rough handling or exposure to abrasive materials. Avoid dropping the tumbler and refrain from using abrasive cleaning pads. While this affects the appearance, it typically does not impact the tumbler's insulation performance.
