2. Daily Cleaning:

   • After each use, wash the flask using warm water and mild dish soap.

   • Use a bottle brush to reach inside the flask and clean thoroughly.

3. For Deep Cleaning or Odor Removal:

   • Fill the flask with a solution of 1 tablespoon of baking soda and hot water.

   • Let it sit for a few hours or overnight, then scrub gently with a bottle brush and rinse well.

   • You can also use a vinegar and hot water solution for stubborn stains or odors.

4. Exterior Care:

Care Instructions:

• To maximize heat retention, pre-warm or pre-chill the flask with hot or cold water for a few minutes before filling.
