We recommend that you only put water in your flask to optimize its hygiene and facilitate its maintenance. Do not use abrasive products for cleaning. The silicone tip is completely removable and very easy to clean.

Flask maintenance advice: Wash in boiling water or in the dishwasher after each use. The flasks are consumables whose wear and tear will depend on your use. We advise you to renew them every year, depending on your frequency and mode of use. The silicone tip should be changed regularly.
