How do I remove discoloration on the inside of my Thermos product?
If you see discoloration, it’s almost always a coffee/tea build-up in your container. Coffee pot cleaner or denture tablets usually work the best for getting out stubborn stains and odors. Put two denture tablets in your product with hot water and let it soak overnight then wash with soap and water and rinse well, and if applicable, allow to dry, prior to use. Lemon juice can also be used for removing odors.
