Before You Start

Prepare a clean workspace and gather your tools. Empty the bottle and remove the lid. Use warm, not boiling, water to avoid warping or damaging finishes. Avoid harsh chemical cleaners, which can affect taste and safety. Allow time for air drying to prevent residual moisture buildup.

For narrow-mouth bottles, a dedicated bottle brush helps reach the interior walls. For dark or stubborn odors, consider a short soak with the cleaning tablets, following product directions carefully.

Step-By-Step: How To Clean Hydro Flask

Rinse the bottle with warm water to remove loose debris and residue.
Disassemble the lid and brush components to reach all crevices.
Use the Hydro Flask bottle cleaning brush set to scrub the interior walls in a vertical motion.
Scrub the mouth and thread area thoroughly to remove mineral buildup.
Fill the bottle with warm water and add a cleaning tablet bottle as directed; let it sit for the recommended time.
Rinse the interior multiple times until the water runs clear and free of tablet residue.
Use the Hydro Flask lid cleaning brush to scrub the lid, threads, and seal area; rinse well.
Rinse all components one final time and place on a rack to air dry completely.
Reassemble once dry and inspect for any missed spots or lingering odors.
For difficult odors, repeat with a fresh cleaning tablet or swap to warm water and mild soap as needed.
Store with the cap off to improve airflow and prevent moisture entrapment.
Establish a regular cleaning routine, especially after beverages with strong colors or scents.
