I got a few of these clearomizers: Vision CE5 eGo Clearomizer (Clear) [VISCE5EGOCLEAR] - $5.99 : and i'm very pleased with the performance. great vapor production, decent taste, always a good throat hit (sometimes depending on the juice). Down to my real question: how to clean and maintain this item. I have tried soaking in coke, then washing in water, and then dry burning. I saw a youtube video that said soaking in coke was a great way to clean atomizers, however after doing the previously mentioned process, my vapor production has gone wayyyyyyyyyyyyy down. Did I ruin my clearomizer? Or is there hope for me yet.
