Hey all, I have read lots of stuff about putting cinnamon flavored juice into clearos, etc. Well, I forgot what I read and put some cinnamon juice in my Stardust yesterday. It didn't break apart, but, it looks like it etched the inside of the Stardust. Does anyone know if it's still ok to use? Or should I just toss it? So, if this is a common issue, why is cinnamon juice even made?
