Designed for durability and optimal temperature retention, this 30 oz tumbler is suitable for a variety of beverages, keeping them cold, iced, or hot for extended periods.
Product Features
- Double-Wall Vacuum Insulation: Keeps beverages cold, iced, or hot for hours, reducing the need for frequent refills.
- Advanced FlowState Lid: Features a rotating cover with three positions: a straw opening with a splash-resistant seal, a direct drink opening, and a full-cover top for enhanced leak resistance.
- Ergonomic Comfort-Grip Handle: Designed for easy and comfortable carrying.
- Durable Construction: Made from 90% recycled, BPA-free stainless steel for long-lasting use and environmental responsibility.
- Dishwasher Safe: All components are safe for cleaning in a dishwasher.
- Car Cup Holder Compatible: The narrow base fits most car cup holders (excluding 64oz models).
- Reusable Straw Included: For convenient sipping.
Setup
- Unpack: Carefully remove all components from the packaging.
- Initial Cleaning: Before first use, wash the tumbler, lid, and straw thoroughly with warm, soapy water or place them in a dishwasher. Rinse completely and allow to air dry.
- Lid Assembly: Ensure the silicone gasket is properly seated within the lid. Insert the reusable straw into the straw opening if desired.
Operating Instructions
- Filling: Fill the tumbler with your desired beverage. Do not overfill; leave space for the lid.
- Securing the Lid: Place the FlowState lid onto the tumbler and twist clockwise until it is securely tightened.
- Lid Positions: The rotating cover on the lid offers three positions:
- Straw Opening: For use with the reusable straw. The seal helps resist splashes and holds the straw in place.
- Drink Opening: For direct sipping without the straw.
- Full-Cover Top: Rotate the cover to fully close both openings for maximum leak resistance during transport.
- Carrying: Use the ergonomic handle for convenient transport. The narrow base is designed to fit most standard car cup holders.
Maintenance and Care
- Dishwasher Cleaning: All components of the STANLEY Quencher H2.0 FlowState Tumbler are dishwasher safe. Place them on the top rack for best results.
- Hand Washing: For hand washing, use warm water and mild dish soap. A bottle brush may be helpful for cleaning the interior of the tumbler. Ensure all parts, especially the lid and straw, are thoroughly cleaned to prevent residue buildup.
- Drying: Allow all components to air dry completely before reassembly or storage to prevent odors and mildew.
- Avoid Abrasives: Do not use abrasive cleaners or scrubbers, as these can damage the finish of the tumbler.
Troubleshooting
- Liquid Not Staying Hot/Cold:
- Ensure the lid is securely tightened and the rotating cover is in the full-cover position when not actively drinking.
- Check that the silicone gasket in the lid is properly seated and free from damage or debris.
- Leaking:
- Verify the lid is fully tightened.
- Confirm the rotating cover is in the full-cover position for maximum leak resistance. Note that the straw opening is designed to resist splashes but may not be entirely leak-proof if inverted.
- Inspect the silicone gasket for proper placement and any signs of wear or damage.
- Difficulty Cleaning:
- For stubborn stains or odors, a mixture of baking soda and water can be used. Let it sit for a few hours before scrubbing and rinsing.
- Ensure all parts of the lid are cleaned, including under the rotating cover.
