Abstract

A washing device for a vehicle accessory that includes a washer housing with a ring portion and a fluid source attachment. The ring portion has a main opening for receiving a portion of the vehicle accessory, an attachment side configured for mounting the washer housing, a washing side configured to frame the vehicle accessory, and a transition portion between the ring portion and the fluid source attachment. A nozzle end of the fluid source attachment has at least one fluid channel defined by a nozzle protrusion on the nozzle end. The fluid channel is configured to discharge the fluid to the washing side for cleaning the vehicle accessory by creating a plurality of fluid flow pathways of the fluid between the nozzle end and the transition portion, wherein the plurality fluid flow pathways interact with one another to form at least one vortex in the flow of the fluid.
