atty clean that works for me: half an empty film cannister of vodka or pga....drop in the dirty atty, cap off and shake well. Blow out any excess from both ends and dry burn until no vapor. repeat cannister soak/shake. Blow out any excess. Add 5-7 drops of juice and vape away. I found if I did not rinse after the dry burn that flavor is not as good so now do not do a second dry burn just add a little juice to the damp (not wet) atty after the final rinse.
