DO NOT PUT SCENTS IN YOUR FOG MACHINE!!!!!! it will sooner or later screw up your machine, it has been proven!!! do not put anything else through the fog machine either!!! it will also screw it up! this is coming from a guy with experiance!! and most fog juices don't smell to bad either, so adding scents just makes it more obvious!! soryy to yell, but if do do any of those things, you will find that your fog machine will have a short life!
