A cleaning accessory tool for wiping ceiling or wall tile support grids which includes a elongate, flexible wiping element movably mounted between releasably fixed positions over a wiping element support surface carried by an elongate handle. In a preferred embodiment, the wiping element is in the form of a relatively long endless belt of a flexible, absorbent material which is selectively advanced over the support surface after a given wiping stroke to expose a clean, unused portion of the wiping element for the next wiping and cleaning stroke. Also disclosed are modified configurations which increase the effective length and usable surface area of the wiping element to effectively clean the grid structure.
