Glad to see you got your cleaning schedule worked out JD, most people wouldn't even consider cleaning their atomizers at all never mind once a day.
A dirty atomizer performs like poo, the wicking gets clogged, the air flow is not optimum, the coil heats unevenly, and could start to leak. If its under performing, clean it, no matter how much time has gone by from your last cleaning, this holds true for any atomizer. If it's cleaned often enough ( use and juice dependent) a quick soak and blow out is all it needs, if you let it go to far it will get to the point were cleaning wont help. If the carbon build up on the coil gets to heavy, you went beyond the point of no return and it will work like crap and probably go cold.
