Scotch-Brite™ Ultra Fine Scuff Sponge is a great hand-held cleaning agent designed to help with intermediate scuffing applications. Under a microscope, an ultra-fine grade reveals tiny, small, densely-packed mineral that counters the more aggressive cut of a denser grade abrasive. The fine grade produces a finer finish that will not compromise the geometry of the part by gouging or marring it. An Alternative to Steel Wool Unlike fine steel wool, Scotch-Brite™ Ultra Fine Scuff Sponge will not rust after use or leave fine metal splinters. The durable open-web construction is load resistant, offers long life and consistent abrasive action for cleaning and scuffing with no need to adjust, turnover or continue the same project with a new sponge. The sponge gets into corners and works detailed surfaces without altering the dimensions of the base material. Designed to run cleaner and longer than steel wool, this versatile sponge is a useful item for any workshop. It can help reduce surface prep time on a variety of applications including paint and primer preparation on airplanes, cars, trucks and other motor vehicles, scuff sanding of sealer coatings on cabinetry and furniture, refine finishes on stainless steel appliances, food processing, pharmaceutical and surgical equipment. Designed for Comfort Our Scotch-Brite™ Ultra Fine Scuff Sponge was designed with comfort and conformability in mind. The contours in the center of the sponge may help operators achieve a firmer grip, so they might apply more uniform pressure to the substrate. It comes in white, grey and maroon colors to indicate the sponge's grade. The sponge's material works great with water or other solvents. The Many Benefits of Open Web Abrasives Overall, our nonwoven technology makes Scotch-Brite™ industrial abrasives unique. A combination of fiber strands, resin, and abrasive mineral forms a thick, open web. The spring-like nature of the fibers responds to contours and effectively removes unwanted burrs, soils, and contaminants while maintaining the geometry of the workpiece, which in turn reduces rework and boosts productivity. Gaps in the web allow swarf to escape, so debris does not clog the mineral. Fibers in the web continually break down with use to reveal fresh mineral for exceptional consistency, superior cut performance, and extremely long service life. Scotch-Brite products not only enhance productivity, but also increase operator safety by reducing the need for cleaning chemicals and pastes, and replacing wire brushes that can break off and cause injury.Scotch-Brite abrasives work fast and deliver consistent results, part after part.
