Lots of folks
vape directly from the atomizer for various reasons, but cleaning is not one of the reasons I am familiar with. I assume you have spare atomizers on hand. If so, you can use the one that is not producing much vapor and try the dozens of revival methods in the various
threads on the forum. Since no one has found an ideal solution, all you can do is try several.
One idea that sounds very interesting comes from a vaper in Germany who uses the steam valve on an espresso machine to clean atomizers. If I still had my espresso machine, I certainly would try it first.
