Yeah, this method is the best to clean an atty, a Joye510 or a 306 will last forever with this process. I just wanted to share something, I don't know if it has been covered before on the forum but...
I've been trying different atomizers or systems (DCT, Vision, Vivi Nova. I know, I'm too late to the party) but the thing is that my 510 attys haven't seen so much activity because of that. So, what I've noticed is that if you leave a used atty lying arround, the juice that is inside is going to oxydize and turn brown, so when you want to use it again you get a very weak performance, even if you add new juice to it.
Don't think that your atomizer is dead, you just have to remove the old juice and clean it with a nice rinse-dry burn process and your atty will be just like new!!
