Good point.
So we're basically talking about cleaning out old dried up juice in the mesh that could be clogging things up?
If so, I have seen so many different cleaning methods and materials, each with groups of folks that swear by them.
Personally, I believe rinsing an atomizer out with very hot water works just as good as anything else.
I guess we'll probably never see anyone do a full blown test with pictures and everything for just cleaning out juice from the mesh.
In the absence of such a test, it looks like this debate will rage on forever.
