Tip from Susan from Michigan

To clean the atomizer, “spin” the ends of a cotton swab (Q-tip), around
between your thumb and pointer finger so there are no loose cotton
particles. Dip in rubbing alcohol and swab well around the inside of you
atomizer. The dry end of the swab may be used to remove any excess debris or
alcohol remaining. Rubbing alcohol dries very quickly so there will probably
be no need to dry, but if desired a hairdryer on cool setting may be used.
Atomizer “buzzes” like new!
