A surface treatment tool formed from a thin sheet of flexible material, typically a polymer, shaped to store and dispense fluid, scrub, abrade, scrape off and retain debris, including particulates from treated surfaces, and including an array of closely spaced hollow mushroom-shaped protrusions that store (after a bottom sheet which is not shown is added), and then release fluids during rubbing via perforated faces, and upstanding mushroom shapes carrying soft rubbing faces which have harder scraper edges constituting operable faces with gaps between faces leading into a sunken labyrinth into which loosened debris is scraped up and retained. |
