2. Setup
Initial Cleaning:
Before first use, wash all components of the tumbler (body, lid, and straw) with warm, soapy water or place them in the dishwasher. Rinse thoroughly and allow to air dry.
Lid Assembly:
- Ensure the silicone seal on the lid is properly seated.
- Align the lid with the tumbler opening and twist clockwise to secure it tightly.
- Insert the reusable straw into the designated straw opening on the FlowState lid.
3. Operating Instructions
Using the FlowState Lid:
The FlowState lid offers three positions for versatile use:
- Straw Opening: For sipping with the reusable straw. The seal helps hold the straw in place and resists splashes.
- Drink Opening: For direct sipping without the straw.
- Full-Cover Top: Rotate the silicone cover to fully close the lid for enhanced leak resistance during transport.

Temperature Retention:
The double-wall vacuum insulation maintains beverage temperature effectively. Cold drinks with ice can stay iced for up to 40 hours, and hot beverages remain hot for up to 9 hours (for the 30 oz model).

Car Cup Holder Compatibility:
The tumbler's narrow base is designed to fit most standard car cup holders, ensuring your hydration is always within reach while on the go.
4. Maintenance
Cleaning Instructions:
The STANLEY Quencher H2.0 FlowState Tumbler is dishwasher safe. For best results, place the tumbler body, lid, and straw on the top rack of your dishwasher. For hand washing, use warm water and mild dish soap. Ensure all components are thoroughly dried before reassembly or storage.
5. Troubleshooting
Lid Leakage:
While the FlowState lid is designed to resist splashes, it is not 100% leak-proof, especially if tipped over or inverted. Ensure the lid is securely twisted onto the tumbler and the rotating cover is in the full-cover position for maximum resistance against spills.
Straw Dislodgement:
The straw is designed to stay in place when the lid is properly assembled. If the tumbler is tipped, a small amount of liquid may escape, but the straw itself is unlikely to completely dislodge from the lid's seal.
