I would recommend anyone who finds in the oral irrigator that the water pressure when brushing shower after leaves, the Water Jet spare nozzle with a new interchanges. Thus, it does not even come to recommend to completely clean the dental water jet with a detergent. In course of time the nozzles contaminate with limescale. It is best when the water jet nozzle flushed with the cleaning agent on a monthly basis. After replacing the Water Jet nozzle showering with the water jet nozzle was again 100% strength in order.
