This Whirling Spray also allows you to use it as a Rectal Syringe by removing the Whirling Nozzle as well as the rubber cap at the foot of the nozzle. Cleaning: Should be cleaned after every use using warm soapy water. Insert the nozzle into the water, press the bulb to expel the air and allow the water to be sucked into the bulb. Repeat with clean water. If you wish you can remove the nozzle from the bulb for easier drying.
