Clean Abrasive with Carpet

What happens here

With the carpet in place, take your power sander (if using sanding discs) or sanding block. While the sander is running (for power sanders), or by hand (for sanding blocks), gently but firmly tap or rub the loaded abrasive surface against the indoor/outdoor carpet. The coarse fibers of the carpet will effectively dislodge the embedded paint, wood dust, or coating particles from the abrasive surface. This method works for both coated abrasives (like sandpaper discs) and foam abrasives (like sanding sponges).
