A disposable cleaning pad having a grout cleaning brush includes a bristle attachment for use with a disposable pad. The bristle attachment is molded into a rectangular base piece forming a stand-alone removable brush that can be removably attached to a disposable pad. A top rectangular piece of similar dimensions to the base is connected to the end portion of the base by way of a hinge. The ends opposite the hinge have mating clasps that allow for the brush assembly to be securely yet removably fastened to an existing cleaning pad which is then mounted in the normal manner to the cleaning system. The brush assembly enjoys a longer life than that expected from a disposable cleaning pad thus the brush assembly may be reused many times before it needs to be replaced.
