Can you clean the atomizers with a solvent alcohol or acetone? 

I would say no but I may be wrong. I clean mine with hot water and pure white vinegar. I get my water to a boil, let it cool for a bit and add it to an equal amount of vinegar. From there I plop the unit in the mix and let it soak for a few minutes. I then use a clean spoon to take it out, blow in the bottom of the atomizer (not too hard but enough to clear out the mix). Then I shake it in the hot water alone, then put it back in the mix. I'll rinse and repeat a  few times and then when done, blow it out a bit, and air dry it on paper towel.

The first start up after the cleaning I "prime it" with a non nic ry4 type stuff. As clean a juice as I got.

This is what I do and it works great and the cleaning solutions are non toxic.

Don't use alc or acitone..  Don't forget that it is a electonic device.. Those are flamable liquids.. And not to say what it could do to your health..  Never.... USE  Water hot and if you want vinigar..

I soaked mine in rubbing alcohol, then rinsed it with water, blew thru it and dried it with toilet paper, being careful not to leave paper fibers on the wick.  Working good now, maybe I got lucky.

http://You will need 6% or 20 Volume [clear liquid] Hydrogen Peroxide (available at any Beauty Supply store), and a syringe.
______________________________________________________________________

For Pen Styles:

Place one finger over the hole [at the battery end]. Draw up the Peroxide solution into the syringe, and dispense enough into the atomizer chamber (or onto the atomizer) to cover it completely. Place another finger over the top (cartridge end) of the atomizer chamber (pen style), and shake. Keeping finger over the "battery" end, wait ~20 seconds. Empty the Peroxide out of the chamber over a drain. Carefully blow twice through the battery end, and shake out any excess. Invert the chamber (atomizer end down), and place it onto a dry tissue, overnight.

For Mini styles, you will need a small plastic jar:

Place atomizer into the bottom of the jar. Add 6% Clear Hydrogen Peroxide to cover the atomizer completely. Swish the solution solution through the atomizer several times and let sit for 5-15 minutes. Swish one last time before carefully pouring the solution out of the jar. Carefully remove the atomizer from the jar and carefully blow through the bottom hole twice. Invert (atomizer side down) on a dry tissue overnight, to dry completely.

I have tried all suggested methods (I have the time), and the peroxide cleaning method is by far the most effective and the easiest.

Great , I'm allways looking for new ways to clean then..

I just used the best way to clean them.. Useing club soda.. Take the atomizer and blow out the excess juice.. Then take it and put it in club soda. Let it sit for 2 hours. The acids will clean it well. I evey once and a while I take my long tweesers and shake then back and forth.. Then let them sit.. After the 2 hours take it and blow out the club soda.. Take the atomizer and put a batt on it. Let it get hot.. Really hot.. then rinse it with water and blow out. Stick a papper towel in it and let dry over nite.. The dripp a few drops in and you will see a big difference.. 

What is the "Prodigy" all about. I saw the vid clip and am still wondering, what is the benefit?

I have the same question about the USB pass through. What is the benefit? More vapor?

What kind of material is suitable for replacing the fibrous material inside a cartridge, and where would I find it?

Is there a reason for not using hot water? I've been doing it.......have I been doing something I shouldn't? So far I haven't noticed anything but I'm sure you know more than I do so please elaborate. Thanks!

 use hot water..  The way that WAS WORDED  was wrong..  The hot water helps break down the guuu   on the heating element...

Hey H3VAPER, thanks for answering questions. Now I've got another. As of right now (I don't have my 510 yet) I'm using an e-cigar. when I put a new cartridge in it it works great but then it slows down and when I check the cartridge there is a lot of juice left but it just isn't getting down to where it needs to be. Is there anything that can be done about this or is it just one of those things? I've never smoked an e-cigar dry yet. I'm saving the cartridges so I can reuse the juice later but I wish they would smoke till they are dry. I notice you answer most questions here which in turn answers most of my questions but I haven't seen this one yet. Thanks!
