This Grout Cleaning Attachment has a mounted stone-like material that can be profiled for use in cleaning any width grout joint. The 2-3/4" long ‘blade’ edge works by abrading the top surface of the grout. The ‘blade’ edge can be sharpened using 40–60 grit sandpaper. After all grout joints have been cleaned, it is recommended the grout be sealed with the appropriate grout sealer from Gundlach.
