Information answering a few questions about fog and haze in stage lighting situations.
Do you need to use the same brand of fog fluid as your fog machine?
Simply put…no. Although some brand names might be better for your system, using non-brand names won’t necessarily “break” your fogger. The truly important quality of the fog fluid is the purity. If you want your fog machine to last its longest, use the purest quality fog fluid you can find. If you can find fog fluid that is 1.5 parts impurities per million or under you’ll probably do fine.
Can a fog machine be used to produce haze?
Yes. If you want a very light Haze, you can dilute your fog fluid with distilled water until you get the grade of haze desired. (Never use tap water.) When you achieve a light haze, you may not see much fog coming out of the machine, but the air will be full of tiny particles that your lights will be seen shining through. Don’t be surprised if you have to activate your fogger more often than usual. That’s how it works with haze.
Will scented fog fluid clog your machine faster?
Nope. The biggest thing that will clog your machine is accumulated dust or jugs of fluid that have been left open for a long time.
How often should you clean your machine?
A clogged fog machine is trash. There is no reasonable means of removing the burnt clog. To keep it from creating a build up of impurities, run half a cup of UNCLOGIT through it after every 40 hours of operation or no longer than 3 months. This will help prevent clogs from forming. After running the UNCLOGIT through it, you should run a little regular fog fluid through it to provide lubrication for the pump.
