Nuck is the coil in that photo???? that's all the wicking mesh isn't it??
The core the coil wrapped around is that black piece that looks like a rabbit turd.

OK, it took me a while since I don't have any of the smaller tools that would have made this easier.
This is a 2.5 month old atomizer that has been hit daily with (usually pure VG/nic and flavor). I have hit it will all manners of flavors (the majority of them Lorann) and have used quite a few of the bad ones(thick and dark such as coffee, etc).
The mesh received 2 baths in 30% phosphoric acid during it's long illustrious life.
Sorry the pic isn't better, it was the best I could do with a web cam. Here are my observations:
The atomizer itself was very clean. The mesh looks almost new and I could not see any wear in the material.
The wire was clean without any noticeable buildup on the wire.
The core the wire wraps around had a thin hard black layer of what I assume is carbon buildup. I was actually surprised with that since it is very hard to get a good look when the unit is intact.
Pete, I have no idea how you do what you do to your atomizers

Edit: Strange..it wouldn't let me embed the image. Maybe it was too big.

I'd also like to thank you guys for the effort you have put into analysing what's going on.
Here are some atomiser pictures that clearly show the gunk - especially the ones by Trog:

Nuck - did you say already, what device was this? Just the usual voltage? Used with external power pack or usb? Did the 'cleaning cycle' take place recently ?
Thanks for those pics Kate, particularly intereested in the
German forum ones.
Just how many forums (fora ?) do you visit ?
The point of all this of course, is that I don't see VG causing any more buildup than PG. I would run side by side tests but I don't tolerate PG well enough to do a long sustained test. I saw previous mention of tests but didn't find the results. Are they in yet?
I have no agenda and not trying to prove anything. Long ago, I suggested testing only VG+water and only PG+water, particularly with regard to deposit formation and the 'bad smell', as the science suggested that VG decomposition could partly account these.
If you heat VG+distilled water, a deposit is formed. A chemistry book tells that VG starts to decompose at just below the boiling point. So acrolein is a likely intermediary in the formation of the deposit (there are other mechanisms but this is the most likely one).
I just can't understand why Nucks is so clean.....perhaps I should get a 401.
Pete - I agree Nuck's atty is in pretty good shape for 2 1/2 months use. Perhaps the battery is on the powerful side of aveage or something; maybe i will look again through those atty life report threads to find the average for 401s.
ps: Pete, you are invaluable to the forum and contributed so many ideas I dare not begin to list them for fear of leaving any out.
Pete - maybe it's the climate up there in Yorkshire ;
Seriously, perhaps because of the extra dampness of the air (clutching at straws?).
btw, you keep your juices air-tight and out of sunlight, and didn't add tap water ?
I'm in Yorkshire Kin and my atomisers last three to four weeks.
I can see your house from my attic window Pete
