Well, someone is selling what they claim to be "Atomizer Flush". Michael of DigitalCiggz and I suspect from his findings that this is nothing more than PG and ethyl maltol. Not exactly a cleaner, but the excessive amount of EM may mute whatever flavor is in an atty/carto by layering a flavor of cotton candy over the top.
That's not really dealing with the problem.
I've found to date that only a solvent, in the form of drinking alcohol, will actually loosen up any gunk in things and do a more adequate job of "flushing out" any funk that may be in the mechanics. The higher the proof, the better. I don't suspect that people can get their hands on anything like we use, a 200 proof grain alcohol that we need a business license to acquire, but something in the 151 range, i.e. Everclear or Bacardi 151 would certainly do the trick.
I use a small dish, add the attys, booze and let it soak for a few hours, agitating it a few times during the course, draining, blowing out and drying them out for a good 24 hours before attempting to use them.
Cartos, just flush them out a few times, blow them out and let them dry overnight.
DO NOT use something that has a sugary/sweet quality to it, you'd just be ruining the atty/carto by adding sugar to the problem, and that will kill your mechanics.
