Griot's Garage 15548 Pad Conditioning Brush
This uniquely shaped brush makes cleaning your foam polishing pads a breeze. You can use it while your pad is on your machine orbital. Set the speed to the slowest setting, rotate the pad and gently brush the surface clean. Quick, easy and effective. The bristles are made of flexible nylon. I've found it also makes a nice brush for cleaning carpet or hard surfaces. The angled design makes it ergonomically comfortable to use. Not for use on wax pads.
