Hello Rebecca! We're sorry to hear that you find the Oasis difficult to clean. We recommend thoroughly washing and drying your tumbler after each use. The Oasis lid can also be sanitized on the top rack of your dishwasher. Additionally, you can clean the tumbler and lid by shaking a mixture of ice and salt inside of the tumbler, then rinsing well. For storage, we always suggest to keep your tumbler unsealed when not in use to minimize moisture buildup. If you find that you are still experiencing an issue with mold, please reach out to our support team at support@elloproducts.com and our support team can help get a replacement lid sent out to you.
