Hey vapernation…have had this atty for a year. probably used it 14 or 15 times. i clean it every time im done with it…when i clean it i put the plug and condom on the battery side and fill the cartridge about 1/3 to 1/2 full with baking soda and use a dropper to drop white vinegar in with the baking soda , place my thumb over the top to retain the chemical reaction in the cartridge…repeat putting drops of vinegar in until all the baking soda is used up and there is no more bubbling …then i remove the condom and plug and rinse the cartridge in hot runnung tap water and use a q-tip to gently rub awat the residue on the cartridge sidewalls and the mesh…place cartridge on a towel in the dish drainer to dry over night and most of the next day(while im at work). the atty just died on me….soooooo. did it meet expectations and die a natural death or can or should i do something different to get more life/use out of it ???? Thanks in advance..
