Imo, Hydro Vasculum tuum lavare potes.
However, it’s important to note that we don’t recommend putting stickers on the flask and then washing it in a dishwasher or with abrasive cleaners. We also do not recommend using steel wool or scouring pads on any part of your Hydro Flask.
The best way to clean your Hydro Flask is by hand with warm water and mild soap, like Dr. Bronner’s Magic Soap! If you want to get rid of some stubborn stains (like coffee!), try soaking them in a mixture of baking soda and water overnight before rinsing thoroughly with cold water in the morning.
