Abrasive base pads (nylon fiber pads with bonded abrasive particles) are excellent for general base cleaning, buffing out wax, defuzzing bases (removing micro-hairs on ski and snowboard bases), blending in base repairs, cleaning irons and other tools (Useful to keep scrapers, tools, files, diamonds & stones clean and working at their best.), even de-burring edges. Also useful for finding burrs while protecting hands & fingers. (A trick: Flatten 3/8" of both ends by heating with iron to fit in palm sander for faster smoothing.)
I believe that there are various grades of the pads found at hardware stores, etc, some do 'fray' more than others and degrade faster (less durable), leaving more 'fines'. 3M Scotchbright is one decent brand.
