Setup, Compatibility & Care

To begin using your Micro Hydro, simply wash the bottle with warm, soapy water before the first use. While the product is dishwasher safe, hand washing can help maintain the exterior finish over time. Ensure the cap is screwed on completely to engage the leakproof seal. For maximum temperature retention, pre-heat or pre-chill the interior by rinsing with hot or cold water before filling. The bottle is compatible with most standard backpack side pockets and cup holders due to its slim, compact dimensions. Avoid using harsh abrasive cleaners or steel wool on the powder-coated exterior to prevent scratching.
