My cleaning process is very, very simple...and just so everyone knows, I've NEVER lost an atty, after around 6 months of doing this(I've had m40* series, 510, J-118 and 901, all in OEM and generic forms)
1. Blow out all excess or "burnt" liquid. It will probably be pretty dark. Careful, this gets messy sometimes, and if you get enough on your hands you'll get a headrush
2. Go to you kitchen/bathroom sink; Run the water until it is pretty hot. Hold the atty under the stream until the "hair" under the atomizer bridge is clear, or (on m400 series attys) until you can blow through the end and pure water comes out.
3. This might be the most important step: after blowing all the water out of the atty, be sure to load it up with fresh fluid (not too much, now! there will be water left over in the atty most likely) and vape until you get a full hit- repeat as necessary to ensure ALL of the water is out. I think that is what saves my atomizers-I would never, ever soak them in anything for any length of time, nor would I use boiling water-the internals are too delicate. Also, if you do not get all of the water out right away, you could run into problems, or so I've heard. Hope this helps...And that I posted it in the right place.
