*Contigo's marine fungi growing system It will get you sick! Care and use guide never tells you how to take apart and clean the auto-seal button mechanism. What happens when you are drinking, is the fluid get trapped inside the auto-seal button and ... stays there. According to the use and care manual, you only have to rinse with warm water while pressing down the auto-seal button. But there will be still water, unless you keep on pressing the button to dry the mechanism. So better way is, you need to take apart the auto-seal mechanism, which is really hard to take apart and put them back. Also, there are very very small parts and you will lose them while you are washing them. I washed mine in a strainer and one of the small parts (small rubber o-ring) floated out the strainer before I knew it! I found this out when I opened the Contigo to refill my water, I noticed floating pink objects... Which was water fungus... YUK
