The Duŝo's vandal resistant head is designed for easy cleaning. The spray nozzle array is composed of flexible silicon rubber to aid cleaning. For cleaning in-situ take a damp cloth & wipe around the spray plate, flexing the rubber nozzles to remove any debris. If a more thorough clean is required remove the sprayplate with the hex key & multi-tool then clean under running water. Replace the spray plate & screw into place.
