First unthread the Micro Spray from the Stake Assembly or Riser. Then take either a small paper clip, sowing needle, or thin stick pin and insert it into the opening at the bottom of the threads all the way up till you see the pin come through the orifice. Run the pin up and down a few times to make sure you dislodged the material clogging the orifice, then thread the Mister back in. That's it!
BTW (by the way) we also offer a Punch Tool MLA-TOOL that has a removable Cleaning Tool that simply clips in and out of the Tool for easy storage. This Cleaning Tool has a pin perfect for cleaning all our Micro Sprays!
