Abrasive Grit Bristle

Liberty Abrasive Grit Brushes are powerful and convenient replacements for scrubbing pads, lasting more than 100 times longer. As the grit number increases, the brush gets softer. 46-Grit brushes replace black pads and are as powerful as coarse sandpaper. 500-Grit brushes replace white pads and are as soft as polishing powder.
