I have been microwaving water and soaking tanks, cartomizers, atomizers, drip tips etc and then letting air dry. Today I noticed ( on my less used items ) there was still an odor of efluid on them so I heated Vodka in the microwave ( bad use of good Russian Vodka ) and let soak, then emptied and let the items dry. Would straight Grain Alcohol be more of an efficient means, with no after taste left over on the cartomizers/atomizers and tanks? I was thinking generic Everclear at the liquor store might be a good product for this. Plus it will evaporate quickly with hopefully no residue.
