Abstract: A motor vehicle washing apparatus having a brush assembly and curtain assembly for prolonging the life of the brush assembly and the curtain assembly by adjusting the length of elements of each when wear occurs. The brush assembly includes a plurality of brush elements mounted on a rotatable drum by connectors which are removably received in channels on the outer surface of the drum. The connectors engage selected slots of a plurality of slots in the brush elements to allow for selectively and incrementally adjusting the position of a free end of each brush element. In a similar fashion, the curtain assembly has a plurality of curtain elements mounted on a support rod or on an oscillating semicircular drum. The curtain elements each have a plurality of slots therein for accommodating self-orienting removable locking fasteners permitting selective and incremental adjusting of the position of a free end of each curtain element.
