I had one of these in the past. I loved it, it brewed great tea. But after a while, the tea started tasting a bit off. So I ran vinegar through it because i was told it would take away the bitter taste of my tea. Well, that didnt work. I even tried bleach. I ended up having to throw it out. I'm thinking of purchasing another one. Like i said, I loved the taste of the tea it produced. Have any of you ever had one or currently own one? If so, how do you clean it?
