Hi Vall, Thank you for sharing your feedback on the Bentgo® Stainless Steel Insulated Food Container. To prolong the life of the product and preserve the leak-proof seal, we highly recommend hand washing with warm water and soap rather than placing it in the dishwasher. Please also note that this container is not microwave safe. Due to condensation, it’s possible for water to become trapped inside the lid. To remove the trapped water, you can try pressing the valve on the lid and giving the container a gentle shake. Your purchase is also backed by our 2-year warranty, and we’d love to assist further if needed. Please reach out to us at help@bentgo.com or 714-668-0300 so our team can help. Thank you, Jessica Bentgo Customer Service
