Setup, Compatibility & Care
Proper care is essential to extending the life of your glass-lined vacuum flask.
- Initial Setup: Wash the interior with mild detergent and warm water before the first use. Rinse thoroughly and allow it to dry completely with the lid off.
- Cleaning: Use a bottle brush for the interior. Avoid using abrasive sponges or harsh chemicals that could scratch the glass or damage the silicone gasket. The lid should be washed by hand rather than in a dishwasher to maintain the integrity of the seal.
- Handling: Never drop the flask or strike it against hard surfaces. The internal glass bulb is delicate. Always avoid rapid temperature changes—do not pour boiling water immediately into a frozen flask, as this can cause the glass to crack.
