  1. The instructions that come with foger does not mention a screen that needs to be claimed or how you would clean it. also instructions say to give 3 to 5 puff of smoke and not one.Also does mention any cleaner that needs to be used

  2. I have this fog er and have used or previously. Today, I cannot get it to vaporize the liquid – it is getting hot enough but the distilled water I am using to test it will not vaporize.

  3. What acetic solution do you use? I take the best care of my fogger and constantly have issues with clogging. I filter my oxalic acid, flush with distilled water when done, and run rubbing alcohol through. It is as though my pump never worked from the beginning.

  4. This has turned out to be a very expensive squirt gun. No combination of solution volume with heat level produces just fog. Always a squirt of liquid accompanied by some fog. Glowing red heat chamber doesn’t vaporize it all. Tried mineral oil, 91% isopropyl, water
    Both plain and distilled. Not impressed. Sorry
