Title: I like it but......
Review: I received this as a gift and thought it was the best travel coffee mug ever made. Until, that is, I gave it a "thorough" cleaning. Although I'd clean the mug and lid after each use with liquid detergent, I discovered that the lid required a much more extensive cleaning. I was so grossed out to discover how much black gunk collects inside the lid. Cleaning the lid is really difficult/time consuming. I became concerned about the health ramifications. I added dilluted bleach to the lid and let it sit overnight. However, the bleach smell lingered and I found myself not wanting to drink from it. The bleach odor eventually aired out. I currently use baking soda with white vinegar. The two ingredients foam when combined. I still used a long bristled brush to ensure that everything is removed.
