Dear Jim,
We greatly appreciate your feedback and are sorry to hear of the issues that your misting fan is experiencing.
Most of our customers that experience nozzle clogs have hard water that has a high amount of dissolved minerals, which may not affect your faucets but would be a big issue for smaller openings like showerheads and-you guessed it-our misting fan nozzles.
Our recommendation is to equip a garden hose water softener for your XPOWER misting fan so that you can tackle the issue from the roots. Cleaning the nozzle attachments will not prevent rapid mineral buildup due to such a small opening for water, unfortunately. Also, replacement nozzles and different opening sizes of nozzles are available to purchase as well.
Hope this helps!
