An adjustable brush for cleaning grout includes a group of brush mounting constructions slidably disposed on a rigid support track. Each mounting construction is movable, yet selectively held in place along the longitudinal axis of the support track. A brush assembly is removably attached to each brush mounting construction. Each brush assembly includes bristles secured within a bristle holding member, and the brush assemblies are selectively held in place during use.
