4. Operating Instructions
4.1 Filling Your Flask
- Unscrew the desired lid from the flask.
- Pour your chosen beverage into the wide mouth opening. Do not overfill; leave some space at the top to accommodate the lid and prevent spills.
- Securely screw the lid back onto the flask until it is hand-tight.
4.2 Using the Lids
- Carabiner Straw Lid: Flip up the straw mouthpiece to drink. The integrated carabiner allows for easy attachment to bags or gear.
- Flip Lid: Press the button or lift the tab to open the drinking spout. Close firmly to seal.
- Stainless Steel Lid: This lid provides a tight seal for maximum temperature retention. Unscrew completely to drink.
4.3 Temperature Retention
The double-wall vacuum insulation is designed to keep cold liquids cold for up to 24 hours and hot liquids hot for up to 12 hours. For best results:
- For cold drinks, pre-chill the flask with ice water for a few minutes before filling.
- For hot drinks, pre-heat the flask with hot water for a few minutes before filling.
5. Maintenance and Care
Proper care will extend the life and performance of your IRON °FLASK.
- Hand Wash Only: The flask and all lids should be hand washed with warm, soapy water. Do NOT use a dishwasher, as this can damage the insulation and exterior finish.
- Cleaning Straws: Use the provided straw brush to clean the inside of the straws thoroughly.
- Drying: Allow all components to air dry completely before reassembling or storing to prevent odor and mildew.
- Storage: Store the flask with the lid off to allow for air circulation.
- Avoid Abrasives: Do not use abrasive cleaners or scrubbers, as they can scratch the finish.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Flask is leaking. | Lid not properly secured or seal is dislodged/damaged. | Ensure lid is screwed on tightly. Check the silicone gasket/seal inside the lid and around the mouth of the bottle for proper placement and any damage. Replace if necessary. |
| Beverage not staying cold/hot. | Lid not sealed, extreme external temperatures, or flask not pre-chilled/pre-heated. | Verify the lid is tightly sealed. Avoid leaving the flask in direct sunlight or extreme cold for extended periods. Pre-chill or pre-heat the flask before filling. |
| Metallic taste in drink. | Improper cleaning or residue from previous use. | Thoroughly hand wash the flask and lids with warm, soapy water. Ensure all residue is removed. The 18/8 stainless steel is designed not to impart taste, so ensure it's clean. |
