then placing a small amount of rubbing alcohol 70% into the pod, shake it up and let it soak awhile and then turn the filling hole upside down to drain and then letting it sit awhile so all alcohol dries out.
Been a long time away from any factory coils or pods, but don't use rubbing alcohol. You really don't want to be inhaling the residue from that. Use vodka or Everclear, both are potable. Rubbing alcohol isn't.
Whether or not that works, well, maybe. But an rta or rda would be a better choice.
