How to clean the range hood?
Fog makers can be a great source of entertainment for parties, concerts, and haunted houses. But sometimes they need extra care to keep them working properly. Avoid over-cleaning your machine, but use vinegar and other nozzle cleaning methods to keep your fogger working properly.
Rinse the tank with vinegar and water
Exit the fog machine.
Vinegar mixtures can be smelly and have a strong odor, especially when used indoors. To avoid embarrassment, take the smoke generator outside when it needs cleaning. It’s better for you and everyone around you. 
Try cleaning the smoke machine in your backyard, which has access to the outside. If you can’t find a suitable spot, consider cleaning with the garage door open.
Empty the water tank.
Remove the water tank from the machine. Open the lid and pour the remaining mist liquid into the sink. Make sure it’s completely empty.
Don’t worry about flushing the tank after dumping it. A vinegar solution will help you when cleaning your aquarium.
Make a mixture of water and vinegar.
Using distilled water and distilled white vinegar, prepare a cleaning solution consisting of equal parts of each ingredient — half vinegar and half distilled water.
Make sure to only use distilled water, not tap water. Tap water contains minerals that can leave deposits in your car that can build up over time and cause problems later.
Pour the vinegar mixture into the smoker.
Put the reservoir back in the smoker and pour the vinegar and distilled water mixture into the hole. It has to go into the same container that normally fills the nebulizer liquid.
To thoroughly clean the machine, you need a lot of ingredients. The tank should be almost full. For most foggers, this is about half a liter of cleaning fluid.
Turn on the machine and let it run with the vinegar and water mixture.
Rinse with distilled water.
After starting the vinegar and water mixture, add some distilled water to the smoker (don’t mix it with anything) and let it run once. The water will help remove the vinegar smell from the car and clean it up a bit. 
After completing this procedure, allow the machine to air dry.
Clean other parts
Clean your mouthpiece.
Unplug the machine and let it cool completely. Check the outlet nozzle (where the mist steam comes out) for deposits or debris. If you see something, clean the mouthpiece opening with your fingernail or something sturdy.
Alternatively, you can try using a pin (or small needle) to remove any remaining dirt. Insert it into the nozzle holder and remove it from the nozzle holder to remove excess deposits.
Use a damp cloth to clean the outside of the fogger. Make sure to get into every nook and cranny of the machine from time to time to remove dust or debris.
Performing this type of regular maintenance will avoid frequent power cleaning of the machine. It can also extend the life of your fog machine.
