Those Stardusts are notorious for that. For what it's worth, I've vaped tons of cinnamon and citrus juices with the Kangar T3's with no negative impact on the tank. If you are determined to use clearos (and many people, including myself prefer those over everything else) and you want to vape cinnamon or citrus stuff, T3's are your best bet right now, or a vivi with a metal tank (as vivis have been known to cloud and crack on occasion as well.)
