We understand that the taste of plastic can be really unpleasant when drinking from your bottle. Rest assured that the bottle is made of materials that are 100% free of BPA and BPS, so the taste you’re experiencing isn’t a sign of harmful chemicals. To get rid of the taste, we recommend filling 3/4 the way of warm water and a tablespoon of baking soda, and letting the contents sit for approximately 40 minutes to one hour. Once you rinse it out, your bottle should be taste-free and good to go.
