Has anyone had any problems with darker colored juices causing coils to get burned / dirty faster then the lighter colored liquids? I was using Timmy's Double-Double a while ago with a Protank and was finding a coil replacement needed every 2-3 days, I even tried cleaning the coils but it didn't much help 
Anyone know if its the coloring used that's causing this?
Darker colored coffee flavored juices seem to really cause havoc with coils I have noticed.. I suspect its the coloring used but I could be wrong.
