Setup, Compatibility & Care
To begin, rinse the bottle and straw assembly with warm, soapy water before your first use. The bottle is designed to be fully dishwasher safe, making long-term maintenance straightforward. When placing in a dishwasher, it is recommended to put the bottle on the top rack and ensure the straw components are secure. Avoid using abrasive scrubbers or bleach on the exterior powder coat, as this can degrade the finish over time. While the bottle is compatible with standard cup holders, always ensure the cap is fully tightened to maintain its leakproof seal before tossing it into a backpack.
