I've been vaping for 5 months now, but I haven't had any luck cleaning and drying cartomizers. I wash them out by soaking in vodka for 15/30 min (with my attys) and then dry them on a paper towel over night. The cartos always end up water-logged ..... When I fill them with juice, it's so diluted that it doesn't produce any vapor. Any thoughts on what I'm doing wrong? I can dry burn my atty to make sure I get all the water out, but I don't want to do that with my cartos - worried I will scorch them. Help!
