ULV Fogger Cleaning and Maintenance

Ultra-low volume (ULV) foggers need some cleaning and maintenance after each use to ensure that they keep working properly. Generally, every ULV fogger will come with an instruction manual where you’ll find all the cleaning and maintenance information for your particular product.

But if your fogger doesn’t have an instruction manual or if you want additional information about how to maintain your ULV fogger, you’ve come to the right place. We’ve gathered these storage, cleaning, and maintenance tips to help you keep your fogger in shape.

Before servicing your fogger, make sure to unplug it from the power outlet or you’ll risk getting an electric shock.

After Each Use

  • You need to clean your fogger after each use to ensure that it won’t be damaged in storage. This will also make sure that it’s ready for you the next time you need it.
  • When you’ve finished fogging, turn off the adjustment knob before turning off the power. Doing otherwise may damage some ULV foggers because the liquid can drip back through the hose and may damage the fogger’s motor.
  • After turning off the adjustment knob, you’ll need to unplug the fogger. You should only perform other services to the fogger after completing these two steps, for your safety and that of the machine.
  • Inspect the fogger for any damage. Check the key parts of the fogger such as the insecticide container, spray hose, and power cord. If you find damage anywhere on the fogger, repair it according to the instruction manual. Alternatively, you can take the fogger to a certified service station.
  • Remove the insecticide container and clean it. Never leave any insecticide or other liquid in the container for long periods. Clean the container with water until no fogging liquid or residue remains.
  • Clean the rest of the fogger. If your fogger has a detachable hose, remove it and rinse any fogging liquids it may have inside. When the hose is clean, reattach it to the fogger. Clean the liquid pump and its filters. You can find these in the insecticide container, accessing them by detaching the container. If the fogger has been stored for a long time, you’ll need to make sure that the pump isn’t clogged. Also, clean the outside of the fogger with a cloth. This will help you check for any signs of damage on the body of the fogger that may have happened during use. As mentioned above, always empty the insecticide container and rinse it to remove any fogging solution residue.
  • Make sure that you protect the nozzle of the fogger if storing the tool for a long time.

ULV Fogger Storage

As we said before, the fogger needs to be properly cleaned and fully dried before storing it for long periods of time.

You should, of course, remove any fogging solution from the container after each use. But, for long term storage, you MUST always empty the container of any leftover fogging solution. Any solution left in the tank could damage the container and the pumping mechanism, which would make the fogger unusable.

Then wash the empty container thoroughly to make sure it’s ready for storage. And remember to dry the container fully before storage to prevent any corrosion on the tank or on other parts of the fogger.

You should store your fogger in a cool, dry place. Avoid storing the fogger in places that reach very high or low temperatures. And if you’re storing the fogger for longer than eight months, you should fog a few times to make sure that the pump and the nozzle aren’t clogged. Some ULV foggers require you to fog with a special oil after 7 to 8 months of storage but this is usually indicated in the fogger’s instruction manual.

Cleaning Your ULV Fogger

  1. After fogging, remove the insecticide container. Keep the valve open fully and allow the fogger to work for one minute. This will blow out any solution remaining in the tubes.
  2. Flush any residual liquids from the machine. To do so, remove the insecticide container from the fogger, empty it and wash it with clean water. Then, refill the solution container with either water or kerosene, based on the type of fogger and the fogging chemicals you use. If you use water-based fogging solutions, fill the container with water. While if you use oil-based solutions, fill the container with kerosene. Put the container back on the fogger and let it operate for a few minutes. The water or kerosene will clear any leftover chemicals out of the tubes of the fogger. You can also immerse the nozzle of the fogger in the appropriate solvent to clean out any chemical deposits.
  3. After that, fill the container with soapy water and spray it a few times. This will clear out any liquids left in the tubes. Then rinse the container with clean water, spray the clean water out a few times to rinse the tubes, empty the container, and dry everything properly before storing the fogger.
  4. Lastly, remove the air filter. Wash it with water or as written in the fogger’s instruction manual. Then let the filter dry completely before putting it back in the machine.

ULV Fogger Maintenance

Always follow the operating instructions that came with your ULV fogger before using or servicing it.

Check for any signs of wear or damage to the fogger before and after each use. It’s important to look for cracks in fragile parts such as the fogger’s insecticide container and hose.

If you do find any broken or damaged parts, replace them immediately. And use only proper replacement parts that are recommended by the manufacturer.

Finally, remember to lubricate all moving parts regularly. This will prolong the lifespan of the fogger and help avoid corrosion.

Hi Karen,
Thanks for the instructions. What about the cloth filter? Any cleaning recommendations?
Thanks!

    To make sure your fogger performs at its best, you should always take care of the filter. It should be cleaned and dried after every use. Once it’s dry, you should put it back in the box so it won’t get damaged.
