Is there any good way to "flush" a flavor from the tank? I'm using an Alien kit with a Baby Beast. I recently tried a candy cane juice, which I really like, but now when I try using any other juice, the leftover minty-ness lingers and affects the flavor of other juices. I tried rinsing it in water and blotting it with a paper towel, to no avail. Any ideas, or is it just a matter of using it until it finally disburses?
