Care Guide

How to Clean Your Hydro Flask Properly

Use the bottle brush weekly to scrub the interior of tall Wide Mouth bottles — its head design reaches the bottom where residue hides — and the straw brush to clear Flex Straw lids and gaskets. For deep cleaning, sanitize with baking soda and vinegar, rinse thoroughly and air dry. Many Hydro Flask bottles and Flex Caps are dishwasher safe, but straw lids last longer hand-washed with the brush set. Regular cleaning prevents mold in the silicone gasket and keeps cold water tasting clean — the cheapest way to extend a bottle's life.
