Because of the extremely small size of openings, some misting nozzles may eventually clog up. If this should occur, the nozzle should be removed and soaked in the Mist Nozzle Cleaner solution (See the bottle label for specific cleaning instructions). If the nozzle is not completely plugged, but simply sprays improperly, the entire mist line can be flushed with the nozzle cleaner for a preventative nozzle cleaning. The nozzle cleaner is nontoxic and completely biodegradable. See the cleaner label for technical information. Recommended for use with all misting systems.
