I like how the cup compresses and able to fit in my bag but the smell and taste of the silicone and rubber is making my coffee drinking unenjoyable. Unfortunately, after about 10 coffees, I am not using it any longer due to the smell. Otherwise, great idea
Hi Joe! We're sorry the smell and taste is making your coffee drinking unenjoyable -- no one, wants that! We do have a quick trick to help you out though before you give up for good.
For a super deep clean, you can make a paste using white vinegar and baking soda. Apply the paste to the inside of your cup or bottle, and add boiling water to soak overnight. In the morning, rinse thoroughly with fresh water and you're ready to go! Hope this helps!
