Yesterday I boiled out both of my atomizers, and afterwards they both worked like new. I put a few drops of VG in one, got an awesome throat hit, but it quickly tapered off and the drag become harder. Now the aftertaste is a bit nasty, very reminiscent of my carto days. Does anybody have any really good cleaning tips? I feel like I tried most of what's out there - alcohol, boiling, rinsing, blowing, dry burning, etc..................
