Thanks for the feedback, Kit. I guess if I'm going to treat them as disposable (which I am inclined to do), it wouldn't hurt anything to try some warm water and detergent, good rinse, maybe follow up with vinegar and drip dry. That seems safest to me. If it doesn't work, oh well....atomizers can be brought back to life but for how long varies..at the moment there made as disposable personal imo... i don't use any cleaning technique's any more... when the atomizer stops working i replace with a new one.
Cheers,
