Abstract
A car wash brush is constructed by sliding multi-layered, wheel-shaped foam plastic cartridges onto a hub with three keyways formed in the outer surfaces thereof. The cartridges use spacers interspersed with foam layers and adhesively bonded to the foam layers. The spacers have keys which fit into die hub keyways to prevent relative rotation while allowing, longitudinal sliding motion. Multiple cartridges are used to produce a brush of desired length. Old style hubs can be salvaged for use in this construction.
