We recommend that you only put water in your flask in order to optimize its hygiene and facilitate its maintenance. Avoid any abrasive products for cleaning. The silicone tip is completely removable and very easy to clean.

Flasks care advice: Go to boiling water or dishwasher after each use. Flashes are consumables whose wear will depend on your use. We recommend that you renew them every year, depending on how often and how often you use them. The silicone tip must be changed regularly.
