So far I have about 4 generic atomizers that after trying to boil or using alcohol to clean them have VERY hard draws. So far that is the only way I've tried cleaning them. I am reluctant to go buy a steamer because I'm afraid it will not work like the other cleaning methods. Can anyone shed some light on this for me? Does the steaming method really work better than the other methods? These atomizers work but with difficulty. I even measured the atomizers with a multimeter and they all should work great but don't. Any tips?
