- Distilled white water
- Distilled vinegar
- Fog fluid
A fog machine takes fog fluid and produces vapor fog by pumping the fog fluid through a heating element. Sometimes the tubes that carry the fog fluid through the system become clogged. Clogging is more frequent with the use of low-grade fluids, or those with added fragrances or color. When the machine becomes clogged, it will not function properly and may destroy the heating element if you fail to clean it right away. Cleaning the fog machine is a simple task that will save your machine from the trash heap.
Take the fog machine to a well-ventilated area. Drain all fluid from the reservoir.
Fill the reservoir halfway with the distilled water, then add distilled vinegar until you fill the reservoir. The vinegar will dissolve whatever is clogging the machine, and the water will flush it out.
Plug in the fog machine, let the heating element warm up and turn on the fog machine. Let the the machine run until the normal fog flow is restored.
Unplug the machine, and drain the excess water-vinegar mixture from the reservoir. Fill the reservoir with the manufacturer's recommended fog fluid.
Plug in the fog machine, and let the heating element warm up. Turn the machine on, and let it run until it produces fog.
Never run the fog machine when it is empty, which can destroy the pump.
Do not use 100 percent vinegar when unclogging the machine, which could destroy the heating element.
Never clean or drain a fog machine before storing it, or you risk it not working the next time you try to use it.
