Setup, Compatibility & Care

To get the most out of your Micro Hydro, ensure the cap is tightened firmly after every fill to activate the leakproof seal. For optimal temperature retention, pre-heat the bottle with boiling water for hot drinks or pre-chill with cold water for iced beverages before filling. Since this model is dishwasher safe, it can be placed on either the top or bottom rack for a deep clean. We recommend removing the cap during the cleaning process to ensure all surfaces are reached. The durable exterior finish is designed to withstand daily use, but avoid using abrasive scrubbers that could scratch the surface.
