1. Dishwasher Safe
The easiest way to clean your Hydro Flask bottles and tumblers is in the dishwasher. Separate straws, caps and lids, and place on the top rack.
Bottles (excluding the Trail Series bottles) and tumblers are dishwasher safe as long as they don’t have the trademark symbol next to the logo.
Avoid dishwashing cleansers with bleach or chlorine.
