if you leave a clear liquid in a tank with a gunked up coil, the stuff on the coil and the wick will leech into the juice turning it dark.Hey gang. Wanted to see if anyone ordered the fruit delight from derall. I left some in the tank as it had gunked a coil fairly quick, maybe a two hours or so, but after sitting in the GS Air for a few days, it turned from a light clear color to almost black. Anyone else experience that with any of the other derall juices?
