Reuseable straw wash tool assembly

Abstract

Embodiments of apparatus for reusable drinking straw cleaning include a flexible central brush and a plurality of external brushes supported by a hand-held handle. The flexible central brush is passed into one end of a drinking straw and the drinking straw is drawn down into concentrically disposed external brushes. The drinking straw is withdrawn, reversed and the process is repeated. A handle or central bore provides external brush pressure onto the straw when it has been drawn into contact with the external brushes. After both ends of the reusable drinking straw are cleaned, the reusable drinking straw is withdrawn from the assembly and placed in a sterilizing solution or dishwasher, and dried. The flexible central brush is replaced without disassembly of the apparatus. Embodiments provide a support stand to receive and hold the assembly in a vertical position from the bottom of a wash sink.
