Question! Question! Question!! Okay, so I have a cartridge and a cartomizer both filled with some dk juice... I can't say it's some of my favorite juice. After the first cart I'm actually not trying to vape it at all. Does anyone have a tried and proven method (i.e. water/vinegar boiling, ultrasonic, supersonic
) to completely empty the carts or cartos without shmokin' em'?
