Title: Impossible to clean
Review: I thought I found the perfect travel mug, until I used it a few times and discovered that it will never be clean. The rim traps liquid then it drips back down later. I use milk in my coffee and this mug constantly smells like sour milk no matter how much I scour with a bottle brush and sponge, then rinse several times.After cleaning, it always releases a dirty liquid which is disgusting. It is so unsanitary I am throwing it away.If you do buy this, make sure to dry standing up.
