FAQs

Is the Hydro Flask 12 oz Mug truly leak-proof?

The lid is designed to be closeable and splash-resistant, helping to prevent minor spills during transit. However, it is not guaranteed to be completely leak-proof if tipped over or submerged.

Can I put boiling water in the mug?

Yes, you can put boiling water in the mug. The TempShield™ insulation is designed to maintain high temperatures. However, exercise caution when handling extremely hot liquids.

How long does the mug keep beverages hot?

Hydro Flask states that their TempShield™ insulation keeps hot drinks hot for up to 6 hours and cold drinks cold for up to 24 hours, though actual performance may vary based on ambient temperature and usage.

Is the lid BPA-free?

Hydro Flask products are made with BPA-free materials. Specific details about the lid's material composition can usually be found on the product packaging or the manufacturer's website.

Can I use this mug with carbonated beverages?

This mug is generally not recommended for carbonated beverages as the pressure build-up can be hazardous and may cause the lid to pop off unexpectedly or lead to leaks.

Does the exterior of the mug get hot?

The double-wall vacuum insulation is designed to prevent the exterior from becoming excessively hot or cold to the touch, even with very hot or cold beverages inside.

What is the warranty for this product?

Hydro Flask typically offers a limited lifetime warranty against manufacturing defects for their products. Please refer to the official Hydro Flask warranty information for complete details.

Troubleshooting

Mug is not keeping drinks hot/cold as expected.

Ensure the lid is securely fastened. Check for any damage to the lid seal. For optimal performance, pre-heat or pre-chill the mug with hot or cold water for a few minutes before filling with your beverage.

Lid is difficult to put on or take off.

Ensure the rim of the mug is clean and dry. Try rotating the lid slightly as you push or pull. If the lid is stuck, try soaking the lid area in warm water for a few minutes.

Difficulty cleaning the lid.

Disassemble the lid if possible (refer to specific lid instructions if available). Hand wash all parts with warm, soapy water and a small brush. Ensure all components are completely dry before reassembly.

Minor leaks from the lid.

Verify the lid is properly seated and fully closed. Ensure there are no obstructions or debris on the rim of the mug or the lid's sealing surface. Note that this lid is splash-resistant, not entirely leak-proof.

Discoloration or staining inside the mug.

Clean the mug promptly after use, especially with dark beverages like coffee or tea. Use a baking soda paste or a specialized stainless steel cleaner for persistent stains. Avoid leaving liquids in the mug for extended periods.
