How to Change the Nozzle on a Fogger Sprayer

It's essential to clean and change nozzles on fogger sprayers frequently, at least once every eight hours of operation, to avoid clots and residue buildup. With the right instructions, you can easily change the nozzle on your sprayer to keep it running smoothly.
